WOLF CREEK - UNIT 1 3/4 3-31 c

Specification:

Table 3.3-5, items 4b, 6, 7 Justification:

The response times for steamline isolation were changed from 7 seconds to 2 seconds with a note reflecting the fact that the time does not include valve closure time.

This change is required for the sane reasons that necessitated deleting the testing requirements of speci-fication 3.6.3 for the main steam isolation valves (MSIV's); namely these valves cannot be stroke tested prior to entering mode 3 if an accurate evaluation of the stroke time is desired.

Note that the applicable modes for steamline isolation in Table 4.3-2 are 1, 2, and 3 (and specification 3.6.3 is applicable in modes 1, 2, 3, and 4). The MSIV vendor has stated that a reliable determination of stroke time cannot be obtained until normal operating tenperature and pressure are reached in the steam generator, and these conditions are not achievable until mode 3.

The testing of the circuitry necessary for steam line isolation will still be accomplished in accordance with the requirenents of specification 3.3.2 prior to entry into mode 3.

The MSIV's are stroke time tested in accordance with specification 3.7.1.5 and Wolf Creek's ASME section XI Pump and Valve Program (as -

invoked by specification 4.0.5).
