88138‐03INSPECTION GUIDANCE

03.01General Guidance.

a. Electrical components and systems consist of those elements of the facility that are designed to supply, use, control, transform, condition, or interrupt electric power.  This IP applies, but is not limited, to the following safety‐related electrical components and associated items:  (1) raceways; (2) raceway hangers and other supports; (3) switchgear; (4) motor control centers; (5) transformers; (6) batteries and racks; (7) battery chargers; (8) inverters; (9) motor‐generator sets; (10) circuit breakers; (11) relays; (12) electrical penetration assemblies; (13) motors; (14) motor operators on valves; (15) electrical-control panels; (16) local cabinets; (17) limit switches; (18) solenoid valves; (19) emergency power system for principal structures, systems, and components (SSC) loads, and (20) other protective devices.

b. Applicable portions of the CAR, Safety Evaluation Report (SER), and Office of Nuclear Material Safety and Safeguards requests for additional information should be reviewed during inspection preparation.  Determine specific licensee procedural and work instruction commitments relative to construction and inspection requirements for electrical components.  The inspectors should then use the above information during the review of the licensee(s construction specifications, drawings, work, and IPs, to determine whether the above requirements are adequately translated into the appropriate documents.

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

d. The inspectors should bear in mind that NRC(s sample covers only a small portion of the procedures involved.  Thus, substantive errors or departure from requirements identified in NRC(s sample raises the issue of whether the licensee is maintaining adequate control and whether the NRC inspectors and/or the licensee should conduct additional examinations to determine the extent of the identified problem.

e. Findings from this inspection activity should include 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 inspectors should inform cognizant Regional supervision.  The issue should be addressed also at the appropriate level of licensee management.

f. Penetration assemblies, as covered by electrical IPs, refer to assemblies installed in a containment-structure opening (sleeve, nozzle, or barrel) and not to the opening itself.  The containment opening is considered to be a part of the containment structure.

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 02.02a.  The CAR should identify and describe all safety‐related components 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 (such as seismic) are specified, the licensee shall establish means to ensure that the results of this testing are documented, reviewed, and determined to be acceptable.  If this is not performed when components are received, the procedures should specify the organization that will be performing this review and the controls to ensure that all such documentation requirements are satisfied before the component is placed in use.  This is a particularly significant area for NRC review.

c. Inspection Requirement 02.02b.

1. U.S. Nuclear Regulatory Commission, Regulatory Guide (RG) 1.38 [American National Standards Institute (ANSI) N45.2.2] or equivalent requirements relative to storage are applicable here.

2. Electrical components 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 plant.

d. Inspection Requirement 02.02c.

1. Appropriate and adequate construction specifications, procedures, and other work instructions for a particular activity are required to be approved and available before that activity is started.

2. Model number and type (only) are not considered to be adequate identification.  Procedures should specify a unique identification number, along with the model number and name of manufacturer.  Adequate (positive) identification is important because similar-looking electrical components can be significantly different with respect to rating, output, material, etc.  Safety‐related electrical components should be listed in the CAR.

3. Anchor bolts holding or mounting electrical components should be of the type, size and length specified.  Provisions should exist to prevent indiscriminate cutting of reinforcement steel during the drilling of anchor holes.

4. The licensee is required to meet Institute of Electrical and Electronics Engineers, (IEEE) Standard 279, and may be committed to RG 1.75, which endorses IEEE 279 with certain modifications.  For example, procedures should be established to ensure that independence and separation requirements of safety‐related functions from normal operating functions are met.

e. Inspection Requirement 02.02e.

1. The licensee/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 locally mounted components by inspection (QC) personnel.  They should ensure that maintenance requirements while (stored in place( 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.)

f. Inspection Requirement 02.02f.  NRC inspectors who are knowledgeable in the area of electrical systems, in general, and testing, in particular will inspect this area.

1. The CAR should include or reference general testing requirements, and work procedures should provide detailed instructions.  In addition, the QA manual should include general surveillance procedures relative to testing, [i.e., activities should be monitored (inspected or audited, as appropriate), in accordance with established procedures].

(a) These procedures should include verification of the following:

(b) Data sheets (or equivalent) are being used as specified.

(c) Testing procedures are current and approved for use; ranges, accuracies, etc., are specified.

(d) Testing techniques are appropriate for the component to be tested.

(e) Controls are included for removal and handling of components during testing activities.

2. Test data/records should include:

(a) Specific identify of the component tested.

(b) The specific identity of the measuring and testing equipment used to perform the testing.

(c) Identity of the technician performing the test and date of test.

(d) Approval signature of responsible individual.

3. Certificates of calibration should be available at the site for test instruments used to perform tests.  These certificates should show that the standards used to establish the accuracy of the test instruments are traceable to a nationally recognized standard.  Procedures should require that the performance and accuracy of test equipment are demonstrated by periodic checking.

4. This item does not include preoperational testing.  Construction testing generally verifies that certain components perform as intended, but it is not a test of system capability.

5. Typical tests that may be required include insulation resistance, continuity, battery load, and breaker trips.

6. The licensee is required to provide information, relative to protection of the safety‐related portions of the onsite AC power system from certain fault conditions.  Significant aspects of this protection include:  (1) manual and automatic interconnections between buses, buses to loads, and buses to supplies, and capability of components to withstand anticipated fault conditions; (2) interconnections between safety‐related and non‐safety‐related buses; (3) circuit protection network (e.g., selective trip), including setting criteria, protection for overvoltage, undervoltage, and frequency; and (4) load‐shedding devices.

One method to determine the adequacy of these protective systems and devices includes a relay-coordination study.  The inspectors should determine whether provisions are established to ensure that adequate procedures are available for this activity.  The results of this study should be evaluated by qualified personnel to ensure acceptability of the results.

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

a. Adequate procedures or other means have not been established to ensure and document that all safety‐related electrical components and subsystems have met applicable acceptance criteria or are nonconforming in specific areas.

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

c. Inadequate means to control location and status of electrical components; especially during removal for repair, modification, or replacement.

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

88138-04RESOURCE ESTIMATE

This IP is expected to take, on the average, 24 to 32 hours for each review of licensee/contractor activities.  The procedure should be run once early in the installation of electrical components and systems, with primary focus on procedures and personnel qualifications.  A second inspection should be conducted about mid-way in the installation of electrical components and systems, with the primary focus on observation of work and review of installation records.
