The valve redundancy of the reactor coolant sys, tem vent paths serves to minimize the probability of inadvertent or irreversible actuation while ensuring that a single failure of a vent valve, power supply or control system does not prevent isolation of the vent path.

The function, capabilities, and testing requirements of the reactor coolant system vent systems are consistent with the requirements of Item II.8.1 of NUREG-0737,

supporting visual indications of detachment from foundations or -

Snubbers which appear inoperable as a result of visual inspections may be determined *0PERABLE for the purpose of estab- !

lishing the next visual inspection interval, providing that (1) the cause of the rejection is clearly established and remedied for that particular snubber'and for other snubbers that may be generically susceptible; and/or -(2) the affected snubber is functionally tested in the as found condition and determined OPERABLE per Specification 4.7.8.d. (

as applicable. When the fluid port of a hydraulic snubberir is found to be uncovered, the snubber shall be determined inoperable unless it . [

can be determined OPERABLE via functional testing for the purpose of i

, establishing the next ' visual inspection interval.

For the snubber (s) found inoperable, an engineering evaluation shall be (f performed on the component (s) which are supported by the snubber (s). g

- The scope of this engineering evaluation shall be consistent with the /

licensee's engineering judgment' and may be limited to a visual inspec-tion of the supported component (s). The purpose of this engineering evaluation shall be to determine if the ccmponent(s) . supported by the snubber (s were adversely affected by the inoperability of the I snubber (s in order to ensure that the supported component remains

capable of meeting the designed service.

c. Functional Tests i

At least once per 18 months during shutdown, a. representative sample of 10% of the snubbers in use in the plant shal.1 be functionally tested either in place or in a bench test.*4 For each snubber that )

- does not meet the functional test acceptance criteria of Specification 4.7.8.d. an additional 5% of the snubbers shall be functionally tested until no moretested.
