Licensee Action On Previous Inspectior Findings a.
(Closed) Unresolved item (423/81-14-03): The storage of mechanical Snubbers in warehouse was not in cccordance with vendors instruction.
S&W requested vendor to review their storage instructions and verify if the Snubbers can be stored out of original containers and without removal of the pivot pins. The vendor's reply agreed that the storage was acceptable, but suggested that the pivot pins be removed and placed in plastic bags. S&W has started a program to comply with this recommendation. The inspector observed the crafts removing some of the pivot pins from the Snubbers ard placing the pins in plastic bags, b.
(Closed) Unresolved it_m (423/81-04-01):
Conflicting storage require-ments for some Westingaouse supplied equipment. The flux mapping detectors require a level "B" storage. However, Westinghouse also requires a maximum relative humidity of 70%. Normally, when the humidity level is controlled, it is for level
"A" storage. S&W has built a plastic frame enclosure around the flux mapping system and will install a dehumidifier inside the enclosure to limit the humidity.
to 70%.
c.
(Closed)
Construction deficiency (423/81-00-02): The licensee reported to NRC on February 24, 1981, that a potential significant deficiency involving the use of welding procedures in containment fabrication for an application where they had not been qualified. The inspector reviewed S&W documents relating to this matter and noted that a May 28, 1981, letter addressed to the licensee stated that after completing their evaluation they determined it was.not a reportable significant deficiency. The inspector discussed his concerns with this and other significant deficiencies with licensee representatives from the Berlin Office.
It appears that many outstanding items such as 50.55(e) and Part 21 are not being addressed in a reasonable time period. The licensee has since issued a letter dated December 17, 1981, to the NRC stating that they have concluded that this item is not a significant deficiency and are also in the process of reviewing and replying to other outstanding 50.55(e) and Part 21 items, d.
(Closed) Violation (423/81-11-01): The inspector reviewed the corrective actions taken to prevent the use of uncontrolled copies of design documents by crafts for safety related work activities. The following are the specific actions taken by the licensee:
- Notices were placed on reproduction machines (Xerox, IBM, etc.)
stating " Documents not to be used for construction".
- S&W conducted periodic in-process verification inspections to ascertain that uncontrolled copied design documents were not used by crafts. Verifications conducted on September 1, 8 and 9, 1981 were reviewed.
- Training on control of level I design documents was conducted on 9/15 & 16/81 for construction, engineering and QC personnel.
- S&W memorandum dated September 14, 1981, outlined several corrective actions taken to prevent the use of uncontrol.ied machine copied docu-ments.

e.
(Closed) Violation (423/81-09-01): S&W had initiated Engineering Design and Coordination Reports (E&DCR) which did not fulfill the procedure requirements; specifically E&DCR F-S-2683 and PS-S-1004 were incorrectly processed. The inspector reviewed the licensee actions to correct the specific violation and also their actions to prevent it trom recurring. The following items were reviewed:
- E&DCR P-S-3812 was issued to supercede PS-S-1004 and identify a change to S&W Specification C-999.
- Addendum No. 1 to Specification C-999 was issued on October 29,1981, to incorporate the concrete repair procedure and update the control change status.
- SSW Engineering Quality Assurance performed an audit, which sanpled 87 issued E&DCR's. The audit did not find an infonnation type E&DCR which had supplemented or superceded a previou; E&DCR.
- S&W Project Procedure NEAM 38, Revision 6, issued September 22,1981, requires that supplementing E&DCR's are to be used only when it is not practical to issue an E&DCR to completely replace the previous E&DCR.
- The S&W Engineering Assurance Procedure 6.5 Revision 0, is now implemented, and provides details for revising E&DCR's.
- A requirement has been placed upon the Project E&DCR Coordinator to review all revisions and addenda to specifications to ensure that all outstanding E&DCR's are properly listed.
