C Supplement IE Bulletin No. 79-14 SEISMIC ANALYSlo FOR AS-BUILT SAFETY-RELATED PIPING SYSTEMS Discription of Circumstances:
IE Bulletin No. 79-14 was issued on July 2,1979 and revised on July 18, 1979.
The bulletin requested licensees to take certain actions to verify that seismic analyses are applicable to as-built plants. This supplement to the bulletin provides additional guidance and definition of Action Items 2, 3, and 4.
To comply with the requests in IE Bulletin 79-14, it will be necessary for licensees to do the following:
2.
Inspect Part of the Accessible Piping For each system selected by the licensee in accordance with Item 2 of the Bulletin, the licensee is expected to verify by physical inspection, to the extent pri.cticable, that the inspection elements meet the acceptance criter'.a.
In performing these inspectons, the licen'ee is expected to use measuring techniques of sufficient accuracy to delonstrate that acceptance criteria are met.
Where inspection ele nts important to the seismic analysis cannot be viewed because of the: ~1 insulation or location of the piping, the licensee is expected to remove thermal insulation or provide access. Where physical inspection is not practicable, e.g., for valve weights and materials of construction, the license is expected to verify conformance by inspection of quality assurance records.
If a nonconformance is found, the licensee is expected in accordance with Item 4 of the Bulletin to perform an evaluation of the significance of the nonconformance as rapidly as possible to determine whether or not the operability of the system might be jeopardized during a safe shutdown earthquake as defined in the Regulations. This evaluation is expected to be done in two phases involving an initial engineering judgement (within 2 days), followed by an analytical engineering evaluation (within 30 days).
Where either phase of the evaluation shows that system operability is in jeopardy, the licensee is expected to meet the applicable technical specification action statement and complete the inspections T
required by Item 2 and 3 of the Bulletin as soon as possible.
The licensee
