Response

Response:

Based on actual dose data from past testing, it is estimated estimated that alternative performed alternative testing performed 3-cycle interval would result in dose savings of about 600 mRem over three operating at a 3-cycle operating cycles.

Response:

Relief Request Request VRR-012 Solenoid Operated Operated Valve (SOV) stroke times (reference values and values and criteria) are shown in Table 1. When new stroke time data is entered into the 1ST IST database, there is an automated check check for a deviation deviation of more than 12%12% from the mean of the last 10 10 recorded recorded values. This alerts the IST Engineer 1ST Engineer of the need to perform a more detailed analysis analysis of the stroke time data. The 12% 12% is a generic embedded feature of the software software used for tracking and trending stroke times. See Table 2 for a sample of historical stroke time data.

Table 3 provides a sample of Position Indication Indication Test (PIT) history and Table 4 provides a sample of Local Leak Rate Testing (LLRT) history.history.

Note: Out of a total of 3119 stroke time tests recorded in the 1STIST database database for these 32 SOVs, there have been 23 failures. 15 of these failures were attributed to limit switch assembly adjustments. The remaining remaining 8 failures were related to SOYSOV sticking problems.
