On October 8,1984, the licensee submitted to NRC Region II supplementary information for IEB 79-02 'on Florida Power Corporation (FPC) letter 3F1084-0 The . letter stated that licensee site-specific testing of WEJ-IT type concrete expansion anchors showed a 40% to 60% reduction of capacities from the 1982' catalog capacities. The 1977 catalog capacities were used in Crystal River 3 concrete expansion anchor calculation The lette identified that further licensee evaluation of Crystal River 3 safety-related seismically analyzed pipe support concrete expansion anchors was being performed. An NRC inspection documented on RII Inspection Report 50-302/84-32,

.

was ~ performed to . follow-up on the licensee's report and to verify licensee compliance. with IEB 79-02 and IEB 79-14 requirements and licensee-commitments. On March 14, 1985, the licensee submitted a revised corrective

-

action plan to provide for IEB 79-02 requirements. A follow-on inspection to the.above noted inspection was performed to verify licensee compliance with IEB 79-02 and 79-14' requirements and its revised commitment ,

- Concrete expansion anchor capacities' used in-the calculations were compared with the resultslof~the-licensee's~on-site testin It was.noted that some lof the calculations utilized concrete expansion anchor capacities that were interpolated fran the test dat The licensee was informed- that :the '

calculations.should clearly document the source of the capacity used (i.e.,

-interpolated test:value) and justify the value used. Furthermore, it was .

noted that the calculation for pipe support MSH-230 utilized capacities for-1 1/2" diameter. concrete expansion anchors that had been extrapolated from test data. jThe licensee was requested to justify extrapolated data used in-calculations. The above noted items regarding justification and documenta-tion .of interpolated and extrapolated data- were identified as Unresolved Item. 50-302/85-16-02, " Justification of Concrete Expansion Anchor Design

' Calculation Capacities." '

The lic nsee stated that modification packages were being prepared for the large ' are safety-related seismically analyzed pipe supports whose concrete expansson~ anchor safety factors were between two and four. Ninety-nine pipe-supports were identified as requiring additional corrective action. 'Of the

.

99, three pipe supports had been modified. Modification of the remainder of-

'

the pipe supports had not been. started during the_ inspection. Documentation of. inspections for modified pipe supports DHH-521, MUH-556 and SWH-084 were reviewed. MUH-556 and DHH-521 were reinspected by the NRC inspector.and the licensee.' -SWH-084-was not readily' accessible but was partially visible and was' visually inspected for obvious discrepancies. Completed, installed, modified, inspected .and Quality Control' (QC)' accepted pipe support MUH-556 -

piece cH" installation dimensions did not " conform" with the applicable

. approved engineering' drawing In. addition, unauthorized. loads (scaffolding).

were being partially supported tar =the pipe support. No: procedure or '

instructions were available -authorizing or prohibiting installation of scaffolding / staging :on permanent plant equipment. This Jappears to be .in violation of 10 CFR 50, Appendix "B"', ~ Criterion V, and was identified as Violation 50-302/85-16-01, " Pipe Support Installation Discrepancies."
