Response to Request for Additional Information Information Regarding Relief Request    Request VRR-012 for the Inservice Inservice Testing Program Third Ten-Year    Ten-Year Interval Reference 2, Detroit Edison submitted In Reference                      submitted proposed relief requests for the third ten-year    ten-year Inservice Testing Program for Pumps and Valves. In an e-mail from Mr.
interval of the Inservice Mahesh Mahesh Chawla to Mr. Alan Hassoun Hassoun dated March 3, 2010, the NRC requested        requested additional information for Relief Request Request VRR-012, VRR-012, Relief to Perform Position Indication Testing at Appendix J Option Indication                          Option B Frequency. This was discussed    discussed in a subsequent telephone    conversation between NRC staff and Detroit Edison personnel on telephone conversation                                                                  on March 25,  2010. The additional information requested 25,2010.                                  requested by the NRC staff is enclosed.
There are no new commitments commitments included in this document.

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===
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.

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

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.
