Licensee Action on Previously Identified Items (0 pen) Infraction (50-461/S0-02-04) The licensee is not taking prompt corrective action to preclude repetition of items such as Nonconformance Reports and found that in many instances that no corrective action was apparent. These were brought to the attention of the licensee, and a representative of Baldwin Associate's Technical Services and it was found that they were in nonconformance with their procedures.
This item remains open pending action by the licensee to assure that corrective action is taken to preclude repetition.
<
(Closed) Unresolved Item (50-461/80-06-06) General Electric audit of Reactor Controls was considered to be lacking in objectivity.
The licensee stated that this matter would be reviewed during the j
next audit of G.E.-
The inspector reviewed IPC's Audit No. 80-04 l
dated August 4 through 7, 1980 which stated that an audit of RCI l
was performed in July 1980 at the Limerick Site in accordance with l
G.E.'s procedures. However, IPC's audit did not address the objec-tivity of this audit.
l The inspector considers this item closed as RCI is no longer at the Clinton site.
(Closed) Infraction (50-461/80-19-01) Traveler did not indicate the welders identification and weld material could not be traced to a specific weld as required by BTS 402. The inspector reviewed BTS-402

V Revision 16, dated October 27, 1980, " Procedure Specification for the Procurement, Storage, and Control of Welding Filler Materials,"
Paragraph 6.2.1 which was changed to reflect the different require-ments of ASME and AWS welding.
The inspector considers this item closed and in conformance with IPC's response letter (U-0200, Q 37-80(11-12)-6) to RIII.
(Withdrawn) 10 CFR 50.55(e) report (81-02) Welding in containment (container liner, reactor pedestal, and bio-shield structures) using wrong or unqualified welding procedure specifications. The inspector reviewed CPS investigation, " Potential Deficiency 10 CFR 50.55(e)
Investigation Control of Special Processes #81-02," L14-81 (04-20)-6.
Y11412, EEC-216-IPC, which stated the deficiency and found that al-though wrong welding procedures were used the essential variables were the same (preheat, interpass, electrical characteristics). The actions to preclude this problem from reoccurring (not accumented on the appropriate NCR's) was to, (1) Discipline engineers have been directed to specify the type of material to be welded (i.e., A-307 to SA-588) on all new travelers or amendments to old travelers.
P-1 to P-1, etc. will no longer be acceptable. Reference: JEF-126-81, CAR #065, Corrective Action.
(2) Technical Services will continue to specify welding procedures; however, a matrix has been developed, which describes the acceptable welding procedures for the various combinations of base materials, to assist in assuring that the appropriate welding procedure has been specified. Reference: CAR
'
- 065, Item 13, Corrective Action.
(3) Construction and engineering will also utilize the welding procedure matrix to assist in assuring that proper weld procedures are being used and specifying the types of material to be welded respectively. Reference: CAR #065, Corrective Action, JEF-125-81.
(4) Welding of base material combinations not previously covered under procedures approved to specifications have been submitted and approved. Reference: Revision. 10, BTS 499, N-ASTM-A Special, PQR's 90, 91, 92., 93, 94.
The inspector agrees that this item be withdrawn.
(Closed) 10 CFR 50.55(e) report (80-04) Eight (8) embeds for restraints to the two (2) RHR heat exchanger of incorrect size, two (2) of the i
eight were not correctly located. The inspector reviewed the associated l
nonconformance and IPC QA Surveillance Plan and Reports that document l
additional training of QC inspection personnel. The inspector considers this item closed and in conformance with IPC's final Report (U-0162, L14-80 (07-28)-9 with supplement report (U-0166, L14-80 (80-15)-9) to RIII.
(Closed) 10 CFR 50.55(e) report (80-07) Deficient welds on hangars l
supporting the RHR spray piping in containment dome. The inspector i
reviewed IPC memo Q22-80(06-24)-6, Y-10941, that states that of the j
fifty-nine welds reinspected twenty-nine contained defects (undercut, l
slag, and inadequate fillet size, etc.).
