Licensee Action on Previous Inspection Findings I
(Closed) Violation (438/80-27-01, 439/80-26-01): Failure to provide pres-l surizer surge line grind procedure. This violation involved the licensee's (
failure to include instructions for grinding and inspection of the inside diameter (ID) of a piping weld, where this grinding was required to meet i
design requirements specified by drawing. The licensee's letter of response
!
to this violation,-dated January 30, 1981,-has been reviewed and determined acceptable by Region II.
In its letter of response, the licensee indicated that instructions would be provided for the required grinding in a Sequence Control Chart (SCC) to be prepared for the work. The inspector found that,
,
subsequently, the licensee had determined that grinding of the originally I
questioned weld was unnecessary.
However, an' ID grinding requirement was added for another weld in the same line grinding was specified for the 10 of a

.
the first surge line piping weld away from the pipe to safe-end weld. The inspector verified the SCC's had been prepared for grinding and inspection of this weld on both Units and considers the violation closed.
The inspector also asked to see the reports for visual and penetrant (PT)
examinations required on the ground welds.
The licensee was unable to provide the reports and the inspector questioned whether the examinations had been performed.
Licensee personnel initiated an investigation to determine the status of the inspections and reports. The inspector identi-fled his concerns for the missing reports and possibly bypassed inspections as unresolved item 438,439/82-11-02, "PT and Visual Examination of Ground Weld" 4.
Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve violations or devia-tions. A new unresolved item identified during this inspection is discussed in paragraph 3.

Licensee Identified Items (10CFR50.55(e) Items) (Units 1 and 2)
The inspector reviewed licensee identified items (LII's) with cognizant site personnel as described below, a.
Insufficient Information The inspector found that the majority of the licensee's final reports submitted for LII's did not provide sufficient information to permit analysis and evaluation of the deficiency and of the corrective action, and that relevant data was not readily available at the site. Typi-cally, the missing information specifically pertained to how and by whom (functionally) the deficiency was discovered, identification of the root cause, assurance that the full extent of the deficiency has been determined, and the adequacy of the action to preclude recurrence.
The inspector discussed and requested such information from site personnel for the following items:
(1) (0 pen) LII (438,439/79-13-02): Seismic response for primary branch lines may not de conservative.

Safety-Related Piping (Units 1 and 2)
The inspector reviewed the licensee's evaluation and acceptance of apparent forming defects in safety-related = piping as documented on WCR 1756.
The review was performed to verify that the evaluation and acceptance was in compliance with regulatory requirements and FSAR commitments-including ASME '
Section III (74S74) code requirements.
The piping involved was 16 inch piping' spool pieces ~1KE8 and 1KE9 (Unit 1) and 2KE8 and 2KE9 (Unit 2). The inspector examined the outside diameter (00) surface of the subject piping, reviewed the NCR disposition, and reviewed guidance relative to the accept-ability of such conditions provided by the licensee'_s design engineer in memorandum MEB 820312023.
No violations or deviations were identified.
8.
Reactor Coclant Pressure Boundary Piping-Observation of Work and Work Activities (Units 1 and 2)
The inspector selectively observed non-welding related work for reactor coolant pressure boundary (RCP8) piping to verify compliance with regulatory requirements and FSAR commitments - including _ the requirements of the applicable code, ASME Section III (74S74).
Examples of. piping work observed by the inspector were as follows:
a.
Traceability identification on stored piping such as serial number 23-Al-2016-50-1 (Unit' 2)
b.
Segregation of RCPB (ASME Section III Class 1) piping such as that identified in a. above and spool piece 2NV-188 (Unit 2)
