The staff has discussed the requested changes to ite:n 3c under

" Method" column of Table 5.4-1 and item 1c under " Method" column of Table 5.4-4 of the Techqical Specifications with the licensee. The staff and the licensee have agreed that the following sentence shall be added:

"The interna'1 test signal shall be checked and calibrated

~

to assure that its output is in accordance with the design requirements.

This shall be done after completing the external te.st signal procedure by checking the output indication when turning the internal test signal switch." The staff requires this addition and concludes that

~

the requirements of IEEE-279-1971 are satisfied and that these changes are acce'ptable.

7.0 SHOCK SUPPRESSORS, SNUBBERS The Fort St. Vrain Technical Specifications dealing with the Limiting Conditions for Operation of Shock Suppressors or Snubbers state (Section 4.3.10e) that shock suppressors may be added to Class I systems without prior License Amendment to Table 4.3.10-1, provided a revision to Tabl,e 4.3.10-1 is included with a subsequent License Amendment request. The Public Service Company of Colorado elected

~

to update Table 4.3.10-1 listing all Class I snubbers as they are added as a result of refined seismic analyses of their piping systems.

As recommended by IE Bulletin 79-14. PSCo has reviewed their " safety-related" piping systems to verify that the deisgn drawings. correspond to the "as-built" configurations. As a result of this review and additional requirements. PSco has started a reanalysis of their piping systems and additional snubbers will be added or deleted as the analysis dictates.
