88137-03INSPECTION GUIDANCE

03.01General Guidance.

a.The term “cable” includes all conductors such as fiber optics wires, cables, and busbars.  The term “termination” refers to all electric-conductor terminations such as lugs, splices, connectors, and terminal strips that directly contribute to the electrical continuity of the circuit.  Terminations also include potheads, bushing, stress cones, taping, compounds, and other devices or techniques that directly contribute to the continuity of the electrical insulation system.  This IP applies to all IROFS electric power, control and instrument cables, terminations, splices, fire barriers and seals.  

b.Determine specific licensee procedural and work-instruction commitments relative to construction and inspection (QC) requirements for electric cables and terminations.  The inspector should then utilize the above information during review of the licensee’s construction specifications, drawings, work, and inspection procedures to determine whether the licensing document requirements are adequately translated into the appropriate documents.

c.To be adequate, procedure control activities such as receipt, storage, installation, inspection, calibration and testing should contain sufficient detail to ensure that the specific work steps which affect the functioning of the installed equipment will be performed properly.  These work steps are to be identified and adequately controlled.  While reviewing procedures, be aware of, and look for, inadequacies that could lead to construction deficiencies and/or indicate an inadequate management-control system.

d.The inspector should remember that the procedures selected for detailed NRC review cover only a representative sample of the procedures involved.  Thus, substantive errors, or departure from requirements identified in NRC’s sample, raise the issue of whether the NRC inspector and/or the licensee should conduct additional examinations, to determine the extent of the identified problem.

e.Findings from this inspection activity should address each functional area 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 inspector should inform cognizant Regional Management.  The issue should be addressed also at the appropriate level of licensee management.

03.02Specific Guidance.

Note:  The numbering of the guidance below refers to specific subsections of 02, above.

a.Inspection Requirement 02.02.  For the purpose of this IP, the term “work procedures” includes construction specifications, drawings, and work instructions.  (Procedures describing methods of fabrication, construction, and/or installation are sometimes called construction procedures.)

b.Inspection Requirement 02.02.a.

1.Verify that requirements contained in the approved quality assurance program document, or other applicable licensing commitments, have been adequately translated into the licensee’s receipt inspection procedures, including provisions assuring that:

(a)Cable, busways (power, control, and data), and termination materials are in conformance with purchase specifications including special requirements. 

(b)Adequate marking and identification are provided.

(c)As-received cleanliness and protection are adequate.

(d)Receiving inspection reports are complete.

(e)Control and disposition of non-conforming items are adequate.

2.The licensee should identify and describe all safety-related cables and associated items that must operate in a hostile environment (e.g., high radiation, temperature, humidity) during or subsequent to an accident. Where environmental qualification testing or other qualification provisions are specified, the licensee shall establish means to ensure that the results of this testing are documented, reviewed, and determined to be acceptable.  This is a particularly significant area for NRC review. 

3.Inputs from other groups or other organizations (e.g., source inspection results or other required quality tests) to be used during receiving inspection activities are properly used.

4.Procurement requirements such as qualification tests, certificate of conformance, functional tests and other quality tests (material, physical, and chemical) have been successfully completed or status of how and when such requirements will be satisfied is documented and adequately controlled.  Fire barriers and cable-penetration seals may require qualification.  The tests and criteria can be found in the American Society of Testing and Materials (ASTM) E 814 and/or American National Standards Institute/Underwriters Laboratory Inc. (ANSI/UL 1479.)

5.Samples of received electric power, control, and data cable, termination material and related items are subjected to detailed dimensional checks or other inspection to ensure conformance with the purchase specification.

c.Inspection Requirement 02.02.b.

1.Special storage requirements are typically specified by the manufacturer or an industry standard, committed to by the licensee.  The requirements should include such things as taping or sealing cable ends, controlling material and cable or cable reel identification, maintaining proper ambient temperature, separation form nonconforming items, and placement on dunnage.

2.Cable and termination materials may be released for installation on the merits of certifications if the organization involved has established satisfactory program control and audit requirements in this area (ANSI N45.2.1.3).  However, certifications do not release the licensee from having other records for operation and for the life of the facility.

d.Inspection Requirements 02.02.c.  Appropriate and adequate construction specifications and other work instructions for a particular activity should be approved and available before that activity is started.

e.Inspection Requirement 02.02.c.1.(a).  The procedure should require QC acceptance of raceway installations before routing cable.

f.Inspection Requirement 02.02.c.1.(b).  Some method or procedure should be established to assure that the cable is properly qualified for the environment in which it is to be located.

g.Inspection Requirement 02.02.c.1.(d).  Splices in certain locations, such as raceways, may not be allowed. Refer to RG 1.75 and licensee commitments.

h.Inspection Requirement 02.02.c.1(i).  Refer to the following for information pertaining to separation and independence: 10 CFR 50, Appendix A, General Design Criteria 5, 17, 21, and 22; RG 1.75; and the Institute of Electrical and Electronic Engineers (IEEE) Standard  (Std)384.

i. Inspection Requirement 02.02.c.1.(p).  Procedures should require verification that loading requirements (both thermal and mass) are not exceeded in final cable routings in trays, busways, conduits, etc. This verification should include review of actual cable routing, cable routing records, and design calculations.

j.Inspection Requirement 02.02.c.1.(q).  Only specified materials should be used for fire barriers, fire stops, and fire retardants; and installation should be in accordance with approved procedures.

k.Inspection Requirement 02.02.d.

1.The licensee or contractor procedures involved will differ from site to site and may take various forms, such as formal procedures, instructions, checklists, drawings, etc. Review the IPs and compare with the applicable requirements and construction specifications.  Evaluation should indicate whether adequate quality-related IPs are established and are based on appropriate criteria, and further, whether the results of the licensee’s inspection will be transmitted to responsible QA and management personnel.

2.Provisions should include procedures for monitoring or surveillance of installed cables by inspection (QC) personnel.  They should ensure that maintenance requirements are satisfied and that adequate protection is provided against possible damage from adjacent construction activities, including construction traffic.  (Where protective means used during construction may affect proper operation, provisions should be provided for timely removal.)

l.Inspection Requirement 02.02.e.  This item does not include preoperational testing.  Construction testing generally verifies that certain components pass specific tests as required but is not a test of system capability, especially systems that include non-electrical equipment.  The intent of this requirement is to determine whether adequate QA procedures have been established to assure that the required testing is satisfactorily completed and corrective action, if required, is properly performed.  Procedures for cable system and component testing provide means to ensure that:

1.Required construction testing is controlled and performed, as specified, using qualified personnel.

2.Cable systems and components to be tested are properly identified, along with tests to be conducted.

3.Proper type of test equipment (range, accuracy, calibration, etc.) is specified.

4.Test parameters (e.g., voltage level) are according to standards and manufacturer’s recommendations.

5.Special conditions of testing, prerequisites, sequence, precautions, etc., and acceptance criteria, are specified and meet requirements.

6.Type of data to be recorded and method of reporting results are specified.

7.Qualified personnel evaluate test results.

8.Discrepancies are resolved.

03.03Prevalent Problems and Concerns.  The inspector should be alert to problems of a generic nature, such as:

a.Adequate procedures or other means have not been established to assure and document that all QA IROFS systems have met applicable criteria, or to specifically document non-conformances.

b.IPs does not include adequate inspection requirements and acceptance criteria.

c.Inadequate means to control location and status of electric cable and components - especially during removal for repair or replacement.

d.Inadequate procedures to control the evaluation, approval and use of field changes.  (The licensee or contractor also should establish means to assure that only the latest approved field changes and other revisions or changes are being used for installation and inspection activities.)

88137-04RESOURCE ESTIMATE

Procedures should be reviewed (inspection requirements 02.01 thru 02.04) before work is started, and then work observation (inspection requirements 02.05 thru 02.07) should be started while installation is in progress.  Work observation should be completed before work is mostly complete.  Records should be reviewed (inspection requirements 02.08 thru 02.11) for the first time following installation start, and a second review should be conducted before cable installation is complete. 

Depending on the complexity if the system, this IP is expected to take, on the average, 80 hours for each review of licensee/contractor activities, for a complex system.  This IP should be scheduled quarterly during construction activities for completion.
