An approximately equal number of valves shall be tested each refueling outage such that all valves will be tested within a five year period.
If any valve fails its test, an additional number of valves equal to the number originally tested shall be tested.
If any of the additional tested valves fail, all i

15.4.7 MAIN STEAM STOP VALVES t
Applicability i
Applies to periodic testing of the main steam stop valves.
Objective To verify the ability of the main steam stop valves to close upon signal.
Specification The main steam stop valves shall be tested under low flow conditions during
[
reactor shutdowns for major fuel reloading.
Closure time of five seconds or less shall be verified.
The five seconds shall be measured from the time of signal initiation until the valve disc is brought to a halt by the dashpot.
Basis i
The main steam stop valves serve to limit an excessive reactor coolant system cooldown rate and resultant reactivity insertion following a main steam break i
incident.
Their ability to close upon signal should be verified at each scheduled refueling shutdown.
A closure time of five seconds was selected as being consistent with the expected response time for instrumentation as detailed in the steam line break incident analysis.
The test procedure need not require steam to be flowing in the pipe.
Static conditions are acceptable.
The presence of flowing steam or a pressure difference will seat the valve tight, i
