d SNPS Item #4 - Safety Related Snubbers which will be listed in the Tables of.STS 3/4.7.9.
Prior to installation, all safety related snubbers are opera'-
tionally stroked to determine that they-are not frozen, seized 4
or jammed.
After installation and no more than 6 months prior l
to system pre-operational testing, snubbers are visually in-spected for signs of damage or impaired operability as well as for adequate swing clearances in accordance with a LILCO Startup l
organization test procedure.
In addition, their location, orientation, position setting and configuration are verified to be in accordance with approved design drawings.
Fluid level and_ leakage are not applicable to Shoreham as hydraulic snubbers are not employed in any =afety related systems.
The snubber thermal movements for those systems that have oper-ating temperatures in excess of 2500F will be verified during the Startup Test phase under STP-811
" System Thermal-Expansion Test Procedure".
This includes verification of the expected snubber thermal movements and swing clearances.
Discrepancies or-inconsistencies will be dispositioned prior to proceeding to the next test plateau.
A preliminary list'of the snubbers is
. attached.
The final list will be included'in the station tech-nical specifications.
