functional testing, additional sampling is required. due to failure of only one type of snubber, the functional testing results shall be reviewed at that time to determine if additional samples should be limited to the type of snubber which has failed the functional testing.

Steam Generator snubbers are excluded . from the functional testing requirements until the first refueling outage following completion of the SG snubber replacement program.

d,. Functional Test Acce tance Criteria The snubber functional test shall verify that:

1) Activation (restraining action) is achieved within the specified range in both tension and compression;
2) Snubber bleed, or release rate where required., is present in both tension and compression, within the specified range;
3) Where required, the force required to initiate or maintain motion of the snubber is within the specified range in both directions of travel; and
4) For snubbers specifically required not to displace under continuous load, the ability of the snubber,. to withstand load without displacement is verified.

Testing methods may be used to measure parameters indirectly or p rameters other than those specified.
