ATTACHMENTA Add the following to Table 4. 1-2, "Minimum Frequencies for Equip-ment and Sampling Tests":

TEST FREQUENCY

19. Hydraulic Snubber s Fluid Level Check Each refueling for Class II Components and Visual Inspection shutdown Saf e Evaluation A program of hydraulic shock suppressor (snubber) inspection and upgrading was instituted at Ginna in September 1973 to insure the proper operation of the units. Several units fabricated by Bergen-Paterson had been found at other facilities to have experienced seal deterioration. It has been determined by Bergen-Paterson that acceptable seal performance will be obtained if ethylene-propolene seals are used instead of the originally supplied polyurethane seals.

Bergen-Paterson has also recommended inspection at each refueling interval to insure acceptable performance.

Based on the surveillance results of the past twelve months, inspection at each refueling interval will insure acceptable performance for Bergen-Paterson hydraulic snubbers with ethylene-propolene seals and for the hydraulic snubbers fabricated by other manufacturers.

All Bergen-Paterson units inside:containment and six of the thirteen Bergen-Paterson units outside containment now have the ethylene-propolene seals. The remaining seven Bergen-Paterson units outside containment still contain polyurethane material and will be inspected at monthly intervals until such time as the polyurethene is replaced

.by ethylene-propolene Of these smen units, two have been, in,.service ,...

for approximately one year and exhibit no signs of leakage and five do not exhibit significant leakage. No failure is expected in these units since they are in low radiation and low temperature areas.
