PLANT SYSTEMS BASES-To provide further assurance of snubber reliability, a representa-tive sample of the installed snubbers will be functionally tested i
during refueling intervals. These tests will include l
stroking of the snubbers to verify proper piston movement, lock-up and 1
bleed. Observed failures of these sample snubbers will require functional l
testing of. additional units. To minimize personnel exposures, snubbers installed in areas which have high radiat. ion fields during shutdown or in especially difficult to remove locations may be exempted from these functional testing requirements provided the OPERABILITY of these snubbers was demonstrated during functional testing at either the completion of their fabrication or at a subsequent date.
Alternatively, snubbers may be tested on-line.
3/4.7.9 SEALED SOURCE CONTAMINATION The limitations on removable contamination for sources requiring leak testing, including alpha emitters, is based on 10 CFR 70.39(c) limits for plutonium. This limitation will ensure that leakage from
. byproduct, source, and special nuclear material sources will not exceed allowable intake values.
