c I F On January 12, 1974, after achieving the 40-hour stay time access requirement, an inspection of the hydraulic shock and sway arrestors in the drywell was initiated. All units, which included 65 Bergen-Paterson and 25 Grinnell snubbers, were inspected thoroughly and those units un-able to meet the rod freedom, fluid level or no visible Icakage require-ments were tagged for removal. Replacements were made with snubbers rebuilt with the complete ethylene propylene seal kits. Alemite fittings with EP inserts were used on all the rebuilt units which insures that all sealing material is of the recommended type. The inspection of the Bergen-Paterson snubbers located five failed units and one leaking unit which, though still operable, had a low oil 1 cycl. 1hese snubbers were tagged for removal as " failed" to segregate them from other units to be removed. Five Icaking snubbers with sufficient fluid Icvels were also tagged for removal. Of the units tagged " failed," a visual inspection of the seals revealed that some of the seals did deteriorate to a point of failure while others looked in excellent condi-tion. There seemed to be several types of material used in each unit, and to determine which material failed and the degree of the deterioration of the remaining seals, an analysis using infared scans and microscopic examination is being conducted by the GPU Laboratory. A supplementary report of the test results will be generated upon their receipt. During the inspection of the seals, it was determined that two of the failed units had no rebuilding documentation available. Further in-vestigation revealed a total of nine undocumented snubbers from the Septenber rebuilding activities. To insure an accurate record of the material used in the drywell, these nine snubbers were also replaced with rebuilt units. A review of the information obtained from the inspection showed that four of the failed units were located above the biological shield. There were also two undocumented units at that elevation and it was decided at that time to replace all the hydraulic snubbers in that area as a preventive measure to insure units containing.all ethylene propylene seal material in the ' area of the drywell having the worst environmental condi-tions. In addition to the above requirements for removal, twelve old series snubbers had been designated for replacement prior to the inspection. These units were of the type whidi could not be fully rebuilt with the full EP kits. These snubbers were tagged regardless of their condition; however, their condition was recorded on the as found sheets. A total of 30 Bergen-Paterson hydraulic shock and sway ' arrestors have been replaced in the drywell during the shutdown. Of the 30 units, some fell into more than one category. Table I of this report lists all the snubbers that were replaced and the reason (s) for removal. Table II lists the installed units and corresponds with Table I, L

r n pU U - Inspection of the Grinnell snubbers, located on the recirculation pumps, yielded two units which had very littic oil in their accumulator and seven with reservoirs less than one-third filled. The remaining sixteen were in satisfactory condition. The nine units with low fluid levels had their accumulators refilled and one of the two relatively empty units had the coupling between the accumulator and piston housing ti ght ened. The as found and as left conditions are listed at the end of the report. L_.
