Functional or Program Areas Inspected 1.
Follow-up on Licensee Reportable Occurance Reports The subject reports on hydraulic snubbers from 1975 to 1979 were reviewed by the inspector.
After the nationwide seal material hydraulic snubber deterioration problems were first discovered in 1973, the licensee replaced all seal materials in September and October, 1973, and again replaced all seals with ethylene propylene (E-P) seals for Unit 1 in May, 1974, and for Unit 2 in April, 1975.
Since then, only one Grinnell and one Bergen-Paterson (B-P) snubber in Unit I was discovered to have seal material deterioration.
Seven B-P snubbers in Unit 2 had seal material failure (one in May, 1976, four in May, 1977, and two in September, 1978).
The inspector discussed the condition of the Unit 2 hydraulic snubber seal materials with site personnel.
There are 42 safety related snubbers in each unit. The distribution is:
29 B-P inside containment 4 Parker-Hannifin (P-H) I kip capacity units inside containment 9 Grinnell outside containment i855 060
_2_
In Unit 1, 19 hyoraulic snubbers inside the containment were replaced
'
by Pacific Scientific Company (PSC) mechanical snubbers during the last refueling outage. For Unit 2, it is planned that all 33 hydraulic snubbers inside the containment be replaced with PSC units, but there were only 19 PSA-35 size units delivered on site.
The seal material deterioration and the lack of dynamic and environ-mental qualification data for the P-H snubbers were discussed with the licensee. The inspector stated that consideration should be given to replacing all 33 hydraulic snubbers in Unit 2 containment and the remaining 14 hydraulic snubbers inside the Unit I containment during the next refueling outage scheduled for September, 1980. The licensee agreed to consider the inspector's recommendation, and to:
(1) evaluate the reason /cause why E-P seals installed in B-P snubbers continued to fail, and (2) the lack of P-H snubber qualification test data.
2.
IE Bulletin 79-14 Inspection Licensee implementation of IEB 79-14, " Seismic Analysis for As-Built Safety-Related Piping Systems" was reviewed by the inspector.
a.
Review of Procedures and Work Correspondance The inspector reviewed the following document and had no adverse comments.
(1) BAPC Job No. 13524, Procedure 1, " Procedure for Verifying Conformance of Seismic Analysis Configuration to Actual Configuration of Safety-Related Piping Systems in Response to IE Bulletin 79-14", Revision 3, dated September 18, 1979, including the diagram shown in Attachment 2, Project Organizatior..
(2) CEC 0 Maintenance / Modification Procedure W.R. #3815-79, dated August 10, 1979.
(3) CECO Letter to BAPC, " Approval of QA Program for Dresden 2 and 3 and Quad Cities 1 and 2," dated August 10, 1979.
(4) BAPC Interoffice Memorandum, " Personnel Qualification Training Project 13524-021" - a standard personnel certi-fication format.
The inspector reviewed the separation of construction and QC personnel and examined drawings and procedures used for IEB 79-14 activities and had no questions at this time.

Review of BAPC QA Audits
-
The inspector reviewed the following BAPC QA audit reports and had no adverse comments.
(1) Aduit No. 79-14-1 (QA), dated August 17, 1979, audit performed on August 13, 1979, using checklist, " Inspection Elements."
The inspector questioned why there were no subsequent audits on BAPC Procedure No. 1, Revision 2, and Revision 3, based on IEB 79-14, Revision 1, and Supplements 1 and 2.
The BAPC QA auditor stated that a recent audit on Procedure No. 1, Revision 3 was done at the Dresden Site, and since the same procedure is used in Quad Cities, no repetitive work appeared to be warranted. The inspector reviewed the Dresden audit and concurred with the BAPC QA auditor's position.
(2) Audit No. 79-14-2 (Q), dated August 20, 1979, audit performed on August 13, 1979, (re-audited on November 25 December 8, 1979) using checklist, " Inspection Team Member Training and Qualification."
(3) Audit No. 79-14-3 and 4(Q), dated September 19, 1979, audit performed on August 28 - September 19, 1979, using checklists, " Inspection Verification" at.a " Documentation Verification and Sign-Off."
(4) Audit No. 79-14-4 (Q), dated September 26, 1979, audit performed on September 24 - 26, 1979 using checklist,
" Documentation Verification and Sign-Off."

Review of SBAPC Field Inspection Packages Three of the subject packages were reviewed by the inspector.
The findings are:
a.
13524-2-RCIC-12 No adverse comments b.
13524-1-HPCI-6 On the ISI drawing, two consecutive changes in pipe direction
.
were without markings of angles of offsets or directions change coordinations.
1855 062-4-
,
Valve operator orientation in the plane normal to the pipe
,
.
run was not marked on the ISI drawing.
c.
13524-2-RER-8 The air operators on the check valves were not inspected.
.
The BAPC representative stated that only motor operated valve operator had been inspected for orientation and weight. The inspector found no statement in the work procedure to exclude the air operators or any other type of non-manual operators.
The inspector stated that the above findings were considered to be generic problems. The licensee committed to review and evaluate all packages to ensure absence of similar problems and to initiate cor-rective measures if deficiencies were identified.
Exit Interview The inspector met with licensee representatives at the conclusion of the inspection on December 6, 1979. The inspector summarized the scope and findings of the inspection.
The licensee acknowledged the findings reported herein.
