APPENDIX A NOTICE OF VIOLATION Pennsylvania Power and Light Company Docket No. 50-387 This refers to the inspection conducted by a representative of the Region I (Philadelphia) Office at Unit 1 of the Susquehanna Steam Electric Station, Berwick, Pennyslvania, of activities authorized by-NRC License No.
CPPR-101.
During this inspection, conducted on August 21-24, 1979, the following item of. apparent noncompliance was identified.
I.
10 CFR 50.55a Codes and Standards, paragraph (g)(2), states in part that:
"For a boiling or pressurized water-cooled nuclear power facility whose construction permit was issued on or after January 1, 1971, but before July 1, 1974, components (including supports) which are classified as ASME Code Class 1 and Class 2 shall be designed and be provided with access to enable the performance of (i) inservice examination of such component (including supports)...."
The Susquehanna FSAR, Section 5, specifies that the inservice program shall comply with the 1974 Edition of Section XI including the Summer 1976 Addenda of the ASME Code.
Article IMA-1400 of this Code which defines the rules and requirements for inservice inspection states that the owner's responsibilities for the performance of inservice inspections includes:
"The design and arrangement of pipe system components to include allowance for adequate clearances for the conduct of the examinations."
Bechtel procedure M-196, Revision 3, "Design Guidelines for Access for Inservice Inspection",
Paragraph 3, states requirements for weld
- spacing, clearance and access for manual inservice inspection examinations.
Earlier revisions of this procedure stipulate that welds joining fittings to components shall be separated by a spool piece that is six inches long.
Contrary to the above, on August 24, 1979, the constructor (Bechtel) has approved the use of a double-weld joint with overlapping welds attaching the recirculation riser pipes to the ring header sweepolets.
This weld-configuration precludes a satisfactory ultrasonic examination for inservice inspection.
This item is an infraction.
