INSPECTION PROCEDURE 88143

PIPE SUPPORTS AND RESTRAINTS

PROGRAM APPLICABILITY: 2630

88143-01 INSPECTION OBJECTIVES

01.01 To determine whether the technical requirements detailed or referenced in the

facility Construction Authorization Request (CAR), associated with pipe supports and

restraints in Seismic Category I (SC-I) and SC-II systems, have been adequately

addressed in the construction specifications, drawings, and work procedures.

01.02 To determine whether requirements and commitments, in the approved Quality

Assurance (QA) Plan, have been addressed in QA plans, instructions, and procedures, for

pipe supports, and restraints, in SC-I and SC-II systems, and whether they have been

established and installed, in accordance with construction specifications, drawings, and

facility requirements.

01.03 To determine through direct observation and independent evaluation of work,

whether the licensee's work control system is functioning properly and whether the

installation of pipe supports and restraints in SC-I and SC-II systems are in compliance

with U.S. Nuclear Regulatory Commission (NRC) requirements, licensee commitments,

and applicable codes.

01.04 To determine whether: (1) the licensee is adequately implementing the QA

program associated with, pipe supports and restraints, including preparing, reviewing, and

maintaining a system of quality records; (2) the records reflect work accomplishment

consistent with NRC requirements, CAR commitments, and the QA Plan; and (3) the

records indicate any potential generic problems, management control inadequacies, or

other weaknesses that could have safety significance.

88143-02 INSPECTION REQUIREMENTS

Note: These requirements should be implemented so that each major contractor

constructing pipe supports and restraints in SC-I and SC-II systems is inspected. The

number of samples and attributes reviewed may be adjusted on management approval,

depending on the number of contractors and specific work being performed.

Approximately three-quarters of the samples reviewed should be in SC-I systems.

02.01 Review of QA Implementing Procedures. Review QA Manual and implementing

procedures associated specifically with pipe supports and restraints, to determine whether

the commitments in the approved QA Plan are being implemented as follows:
Issue Date: 07/25/07 88143 2

a. Adequate QA audit procedures have been established for this activity, in

accordance with, the approved QA Plan including: (1) scope and frequency of

audits; (2) audit criteria; (3) reporting requirements; (4) followup action; and (5)

resolution of findings by those audited.

b. Provisions have been made to ensure that those engaged in conducting audits are

qualified and have been adequately trained. Provisions must ensure that auditors

do not have direct responsibility in the areas being audited.

c. Means have been established to verify that technical requirements, including

material and component specifications (including traceability and marking

requirements for nuts, bolts and other fastener items), acceptance criteria, and

required documentation are specified in design and procurement documents.

d. Means have been established to verify that any significant design and field

changes from approved drawings are adequately controlled and processed

commensurate with the original design.

e. Provisions have been established to ensure that quality requirements are met

(including documentation that quality requirements of materials and components

are met before installation or use) and that deviations, nonconformances, and

defects are adequately documented and processed through to complete

resolution.

f. The licensee has established a program for ensuring that all craft, nondestructive

examination (NDE), and inspection personnel associated with the installation of

pipe supports and restraints have been trained, or otherwise qualified to the work

procedures involved. Specific attention should be directed toward those engaged

in the installation and testing of concrete expansion anchors, if these are used.

02.02 Review of Work Procedures.

a. Determine whether procedures and instructions (e.g., drawings, specifications,

manufacturers' instructions, etc.) pertaining to pipe supports and restraints have

been reviewed and approved. Make this determination by reviewing an

appropriate sample of work procedures.

The sample should include procedures and instructions for supports on varioussize piping, and instrumentation lines.

b. Determine whether work procedures incorporate the following:

1. Controls to ensure that the type and classification of pipe supports and

restraints comply with approved drawings and/or specifications and meet

licensee commitments.

2. Instruction and precautions to ensure that welding, cutting, forming, heat

treating, and machining are performed in a manner that will prevent the
Issue Date: 07/25/07 88143 3

impact properties of the material from being degraded below specified

values.

3. Provisions for ensuring that required pre-installation and in-process

inspections, as discussed in Section 02.03a, are performed at the

appropriate time.

4. Means to ensure that bolts, nuts, and washers (including lubricant, if used)

are of the proper type, size, and material, with required identificationmarkings; are correctly installed; and, where required, bolt pre-loading

(torquing), minimum bolt embedment, and thread engagement criteria are

imposed.

02.03 Observation of Work and Work Activities. By direct observation, interviews, and

independent evaluation of work performance, work in progress, and completed work,

determine whether activities regarding pipe support and restraint systems are being

accomplished, in accordance with NRC requirements, CAR commitments, and licensee

procedures.

a. Pre-installation Activities. Select three to five supports or shock suppressors and

confirm performance of the following:

1. Pre-installation checks are made to ensure hydraulic units are not installed

if there is evidence of excessive leakage of hydraulic fluid (possible damage

or deterioration of seals), physical damage, or corrosion of polished sliding

surfaces. (Not required if hydraulic snubbers are not used.)

2. Pre-installation check on variable type supports are performed for obvious

damage, rust, or other conditions that may interfere with their proper

operation.

3. Pre-installation checks are made to ensure that bolts, nuts and other

fastener items are available and are of the correct type, size, and material

with required identification markings.

4. Any pre-installation field repairs or adjustments to the units are performed in

accordance with the manufacturers' instructions and specifications, to ensure

that performance requirements are met.

5. Installation equipment such as torque wrenches and other testing and

measuring devices are properly controlled, calibrated, and adjusted at

specified periods.

6. Personnel engaged in the installation of pipe supports and restraints have

received adequate training to perform special processes contained in

relevant work performance and inspection procedures.
Issue Date: 07/25/07 88143 4

b. Installation Activities.

1. Witness portions of the installation activities of five to ten pipe supports to

verify the following:

(a) The latest issue (revision) of applicable drawings or procedures is

available to the installers.

(b) Appropriate personnel approve significant modifications to supports,

before implementation.

(c) The use of jacks or rigging to pull piping into position for hanger

installation or welding does not exceed cold-spring allowances for that

particular material, size, and length of pipe run.

(d) Clearances existing between the pipe and restraints are as specified.

2. Witness portions of the installation and testing of concrete anchor bolts for

five to ten component-support elements (of various types and pipe sizes), to

verify that anchor-bolt type, diameter, embedment length, shoulder-to-cone

measurements, and torque requirements meet installation requirements.

c. Dynamic Pipe Supports. Select a total of five to 10 installed restraints covering at

least three different load classifications and at various degrees (easy or difficult)

of accessibility; and determine, by visual examination, whether the following

conditions meet applicable requirements:

1. Components are free from corrosion or other signs of deterioration.

2. Support plates, extension rods, and connecting joints are not bent,

deformed, loose, or otherwise out of specification.

3. Bolts, nuts, washers, locking devices, and other fasteners are tight and

secure and are of the correct type, size, and material, with required

identification markings. Where required, bolt-tension specification

requirements have been met through the use of properly calibrated bolttorquing wrenches and torque multipliers.

4. Bleed holes are open and free from foreign material.

5. Lubricants and sealants are applied as specified and there does not appear

to be excessive leakage.

6. Seals are not deteriorated (if visually observable without dismantling).

7. Connecting joints, moving parts, piston shafts, seals, etc., are free from

foreign material such as concrete, dropped paint, excessive dust and dirt, or

other material that may obstruct proper operation.
Issue Date: 07/25/07 88143 5

d. Rigid, Constant, and Variable-Type Supports.

1. Select a total of five to 10 installed spring-hanger assemblies covering three

different load ratings and observe the following:

(a) Hanger rods for supporting (2-inch) pipe are not less than (3/8-inch)

diameter, and for (2-1/2-inch) pipe or larger, not less than (1/2-inch)

diameter.

(b) Spring hangers are provided with indicators to show the approximate

“hot” or “cold” position, as appropriate.

(c) Spring hangers enclosed in spaces that will be subjected to high

ambient temperatures during facility operation have suitable service

ratings to accommodate the expected operating-temperature range.

2. Select a total of five to 10 installed pipe supports of different sizes (load

rating) and at various degrees of accessibility. Determine, by visual

examination, whether the following conditions exist:

(a) No deformation or forced bending is evident.

(b) No deterioration or corrosion is evident.

(c) Where pipe clamps are used to support vertical lines, shear lugs are

welded to the pipe (if required by installation drawings) to prevent

slippage.

(d) Movements of pipe from vibration, thermal expansion, etc., will most

likely not cause contact with other pipes, supports, equipment, nor

components. (As best as can be determined after installation, but

before initial operation.)

(e) Sliding or rolling supports are provided with material and/or lubricants

suitable for the environment and compatible, sliding-contact surfaces.

3. Select at least four small-bore or instrumentation lines that have been

designed by a simplified seismic criterion. Determine, by visual examination,

whether the following conditions meet applicable requirements:

(a) The functional restraint direction is proper and in accordance with the

design drawings.

(b) The gaps between the piping and support appear adequate to allow

thermal axial expansion.

(c) The gaps between the piping and support are not excessive for

dynamic loads.
Issue Date: 07/25/07 88143 6

e. Component Supports. Select a total of five to 10 installed component supports,

including at least two multiple pipe supports, and ascertain, by visual examination,

whether the following conditions exist:

1. Component-support elements are located and installed as specified on the

drawings.

2. The surfaces of welds meet applicable Code requirements. Check weld

surfaces for grooves, abrupt ridges, valleys, undercuts, cracks,

discontinuities, or other detrimental indications that appear to exceed Code

limitations.

3. Materials used in the construction of the component supports have been

certified by reviewing material-test reports or a certificate of compliance.

4. Where special bolting materials are specified, check for compliance with

specifications including preload (torquing) requirements.

5. Support clearances are as specified.

f. As-Built Configuration.

1. Select three to seven as-built/final design-pipe-support structural drawings

and compare several selected supports with the actual installation.

Discrepancies observed may result from in-process changes, such as those

initiated in the field. If in-process changes are involved, determine whether

the licensee has properly controlled and documented these changes on a

current basis for engineering review, approval, and subsequent incorporation

into final as-built drawings.

2. Select a total of three to seven pipe-anchor locations on the as-built

drawings [piping (2-1/2 inches) in diameter and greater]. These anchor

locations are designed to restrict individual pipe movement in all directions.

Visually examine these anchors and compare them with the drawings, to

ensure agreement as to their location and function.

02.04 Review of Records.

a. Review licensee and contractor requirements covering the span of records for

piping supports and restraints. Determine the initiation point for those records

sampled and, importantly, the effectiveness of those responsible for reviewing the

records for accuracy and completeness and ensuring that the recorded information

meets documentation requirements. To determine the effectiveness of the

licensee or contractor system for documenting work in this area, review the records

for three dynamic pipe supports or restraints and three fixed pipe supports in the

following areas:

1. Type and classification of pipe support or restraint comply with appropriate
Issue Date: 07/25/07 88143 7

drawings and specifications.

2. Location, spacing, and critical clearances meet licensee’s specifications and

have been verified by licensee QA/quality control (QC) inspection.

3. The required scope of licensee QA/QC inspections was met.

4. Weld identification/location corresponds to respective weld card, drawing,

work order, or other welding documentation.

5. Welding material used corresponds to the material specified.

6. Welders were qualified to the welding procedures used and welding

procedures were qualified in accordance with Code requirements.

7. The records confirm that for welding activities where attachments are welded

directly to piping, the welding specifications used are the same or equivalent

to the ones used for pipe welding, including preheat, postweld-heat

treatment, and NDE examinations.

8. The examination records are complete and meet the inspection and/or NDE

procedure requirements.

b. Review the licensee/contractor system for reporting and disposition of nonconforming materials, parts, and components -- and process or installation

deficiencies, associated with pipe supports and restraints. Review approximately

five to 10 nonconformance/deviation reports to determine whether:

1. The records adequately document current status of nonconformances and

deviations.

2. The records are legible, complete, and indicate that reports are promptly

reviewed by qualified personnel for evaluation, disposition, and prioritization.

3. The records are routinely being processed through established channels for

resolution of the immediate problem, as well as for generic implications.

4. The records are being properly identified, stored, and can be retrieved in a

reasonable time.

5. Nonconformance reports include the status of corrective action or resolution.

6. Resolution of nonconformances is appropriate and demonstrates good

engineering practice.

c. To determine whether qualified licensee, contractor, craft, and inspection

personnel are being used on those special processes associated with pipe support

and restraint installation work, review a sampling of personnel qualification records

(four to six) covering several different disciplines as follows:
Issue Date: 07/25/07 88143 8

1. Determine whether a system of personnel qualification records, meeting

stated requirements, exists and is being maintained in current status.

2. Determine if the records are sufficient to reasonably support qualification in

terms of certification, experience, proficiency, training, testing, etc., as

applicable.

3. Review the action taken by responsible licensee/contractor organizations to

independently authenticate the employment, training, and qualification

history of newly hired personnel.

d. Review relevant portions of licensee and contractor audit reports concerning the

installation of pipe supports and restraints. Review two to four reports to

determine whether:

1. The required audits have been performed in accordance with schedule and

functional areas in established audit plans.

2. Audit findings have been reported in sufficient detail to permit a meaningful

assessment by those responsible for corrective action, final disposition, and

trending.

3. The licensee/contractor has taken proper follow-up action on those matters

in need of correction.

88143-03 INSPECTION GUIDANCE

General Guidance.

a. This procedure pertains to all pipe supports and restraints in SC-I and SC-II

systems. Pipe supports include pipe hangers, restraints, supports, shock and

sway suppressors, etc., that directly support the pipe. Pipe whip restraints, such

as structural steel or concrete barriers that do not normally contact the pipe, are

not covered by this procedure. Additionally, it should be noted that some welding

inspections are included in this inspection procedure (IP). Assistance to the

inspectors in this area may be required. This matter should be considered during

inspection preparation.
Issue Date: 07/25/07 88143 9

b. Applicable portions of the CAR and Quality Assurance Plan (QAP) should be

reviewed, to determine licensee commitments, regarding construction and

inspection requirements, before performing this inspection. The inspectors should

then use these CAR and QAP sections during the review of the licensee’s

implementing construction specifications, drawings, work procedures, and QA

implementing procedures. Most of this review can be completed during inspection

preparation, after these procedures have been obtained from the site. The NRC

inspectors also should review applicable portions of the applicable Code.

c. It is recognized that the construction installation work associated with this IP may

be carried out over an extended period of time, which may require a series of

inspections to fully complete this procedure. Additionally, some licensee

contracting arrangements may be such that several different contractors will be

involved in the installation work. If this is the case, selected parts of this procedure

may have to be repeated, to adequately cover the total effort. Regional

evaluations and appropriate adjustments to this procedure are necessary to

ensure inspection continuity, during the extended period of time involved, and to

accommodate the various contracting arrangements encountered.

d. Considerable impact on the development and structure of this IP has resulted from

a series of problems NRC has encountered at nuclear power plants in the area of

pipe supports and restraints. These problems and concerns are best summarized

in Inspection and Enforcement (IE) bulletins, circulars, and information notices that

have been issued over the years. These documents are listed in the reference

section below. Information contained in these issuances may be beneficial to the

inspectors during implementation of this IP.

e. Findings from this inspection activity should address each element as being

satisfactory, being unresolved and requiring resolution, or being in violation and

requiring correction. When significant inadequacies are identified, indicating

weakness within the responsible organization, the inspectors should inform

cognizant Regional supervision. The issue should be addressed also at the

appropriate level of licensee management.

f. Particular attention should be given to the traceability of material and equipment,

to prevent the use of incorrect or defective materials, parts, and components. The

inspectors should review 10 CFR Part 50, Appendix B, Criterion VIII, “Identification

and Control of Materials, Parts and Components,” and applicable codes and

specifications. The inspectors should verify that the licensee has established

measures for the identification and control of materials, parts, and components,

and for traceability to the approved design basis and to the source. The inspectors

should assure that required identification of the item is maintained by heat number,

part number, serial number, or other appropriate means, either on the item or on

records traceable to the item, as required, and that required markings are on the

item.
Issue Date: 07/25/07 88143 10

The inspectors should note markings on material and equipment and verify that

the markings represent material and equipment as specified by the design

drawings and specifications. In the case of fasteners, compliance with the

applicable material specification [e.g., (American Society for Testing and Materials

or American Society of Mechanical Engineers(ASME)), material and grade] should

be verified by required markings on bolts and nuts and certified material test

reports or certificates of conformance, as required by the applicable procurement

drawings and specifications, and/or by the applicable codes and specifications.

In the case of vendor-supplied equipment assemblies containing fasteners,

samples should be inspected to verify compliance with approved vendor drawings

and specifications, and other information, such as materials used for equipment

qualification tests and/or analyses. Caution should be exercised to ensure that the

required markings on material and equipment, including fasteners, not only exist,

but that the markings indicate the correct material and grade, as specified.

03.01 Specific Guidance.

a. Inspection Requirements 02.01a and b. Audit procedures and/or checklists for

pipe supports and restraints systems should provide for checks of each type of

system used and should, if possible, include representative samples from all

suppliers of components. Audit procedures or criteria should address the

qualifications needed by those performing the audits.

b. Inspection Requirement 02.01f. The inspectors should determine specific steps

the licensee has taken, or plans to take, to ensure that only qualified personnel are

permitted to perform work associated with the installation of pipe supports and

restraints. This effort may tie in with the review of the licensee’s audit plans

specific to this area of work.

c. Inspection Requirement 02.02b2. Most of the welding, cutting, and forming

operations covered by this procedure pertain to component-support structures,

support members, and brackets, and do not require pre-heat-treatment nor

postweld heat treatment. However, those pipe supports, support flanges, or

support brackets that are directly welded to Quality Level (QL-1) pipe may be

subject to preheat and/or postheat treatment. Applicable heat-treatment

procedures are necessary for this type of installation. Records of heat treatment

(time, temperature) must be generated and reviewed for Code compliance.

d. Inspection Requirement 02.03b2. Refer to IE Bulletin No. 79-02 (and revisions),

“Pipe Support Base Plate Designs Using Concrete Expansion Anchor Bolts,” for

general information.

e. Inspection Requirement 02.03e3. The material certificate and identification should

meet the requirements of the applicable Code/Standard.
Issue Date: 07/25/07 88143 11

f. Inspection Requirement 02.03f. The intent is to determine whether pipe supports

and restraints are being installed according to properly approved drawings -- either

the original design drawings or properly approved revisions -- and, if revisions are

in process, that these changes are properly handled in accordance with

established procedures.

Appropriate standards can be used as a guide in this area. For example, ASME

NQA-1 requires that where changes to previously verified designs have been

made, design verification shall be required for the changes, including evaluation

of the effects of those changes on the overall design.

Further, ASME NQA-1 states that records that correctly identify the as-built

condition of items in the nuclear facility shall be maintained and stored for the life

of the particular item, while it is installed in the facility. Additionally, 10 CFR Part

50, Appendix B, Criterion III, states in part, that design and field changes shall be

subject to the same design-control procedures as the original design.

Changes may be made to these supports, during construction, that are different

from the original CAR design. Such changes will result in the accumulation of

various types of design-change documents and/or marked-up drawings. Since

these changes reflect as-built conditions, they should be adequately controlled so

they will be readily available for use with affected original design documents,

during future evaluation on the effect other design changes have on the overall

design. Additionally, the as-built process should result in proper and timely

updating of the original/master drawings and specifications to incorporate such

changes.

g. Inspection Requirement 02.04. The inspectors should bear in mind that NRC’s

inspection sample covers only a very small portion of the records involved. Thus,

substantive errors, or departure from requirements identified in NRC’s sample,

raise the issue of whether the licensee is adequately controlling the process. In

this connection, particular attention should be given to reviewing the adequacy of

those records dealing with the qualification of personnel and QA audits. Problems

noted in these two areas should be viewed as prime indicators of the licensee’s

involvement in the work and the effectiveness with which the licensee maintains

control over the work in progress.

03.02 Prevalent Errors and Concerns. This section is included to provide background on

past problems of a generic nature, that have been identified at nuclear power facilities. This

section is for information only.

a. Welders not properly qualified to applicable Code, and records not properly

maintained.

b. Personnel-qualification records, including indoctrination, training, examinations,

and certifications, either not being maintained, invalid, or nonexistent for some

employees.
Issue Date: 07/25/07 88143 12

c. Field-design work (redesign, modifications) not being processed through

appropriate review and approval route.

d. Nonconformance reports not being processed fully in accordance with established

procedures.

e. Personnel assigned to licensee audit function not appropriately trained in the

assigned audit areas nor independent from areas audited.

f. Licensees and contractors conduct some audits on schedule, but may postpone

or omit others entirely. Although audits are carried out to some extent and may be

adequately performed, in many instances the audit findings and recommendations

are ignored or are filed without appropriate consideration or follow-up action.

g. Refer to Appendix A of IE Bulletin 79-14, for additional problem areas. Other IE

bulletins, circulars, and information notices listed below in the reference section of

this IP contain additional information about problem areas.

03.03 Definitions.

Dynamic Pipe Supports. A pipe-support assembly or restraint, with a hydraulic or

mechanical control unit-designed to prevent unrestrained pipe motion during an earthquake

-- or vibratory pipe movements brought on by the actuation of a water hammer, steam

hammer, pump/start/stop, or safety and relief valve. Thermal expansion of piping is not

restrained by dynamic supports (snubbers, shock suppressors, etc.).

Rigid, Constant, and Variable Type Supports. Pipe support assemblies used for mounting

pipes without hydraulic or mechanical control units (hangers, base supports, saddle

supports, spring hangers, sliding and rolling supports, etc.).

Component Supports. Metal elements that transmit loads between plant components and

the building structure and whose function includes carrying the weight of components or

providing them with structural stability.

Component Standard Supports. Pipe-support assemblies consisting of one or more units

usually referred to as catalog items and generally mass-produced (anchors, guides,

restraints, rolling or sliding supports, spring hangers, snubbers, sway braces, vibration

dampeners, clamps, etc.).

88143-04 RESOURCE ESTIMATE

This IP is expected to take, on the average, 32 to 64 hours of inspection effort per major

contractor. The construction installation work associated with this procedure may be

carried out over an extended period of time, which may require a series of inspections, to

fully complete this procedure. Additionally, some licensee contracting-arrangements may

be such that several different contractors will be involved in the installation work. If this is

the case, this procedure may have to be repeated, in order to adequately cover the total

effort.
