Subject:
Salem AFW Piping Testing Rich, As follow-up to our discussion this morning regarding the Salem AFW piping pressure tests required by IWA-5244 and Salem surveillance requirement (SR) 4.0.5, I did some research on the NRC staff position related to whether the missed surveillance provisions of Salem SR 4.0.3 are applicable to surveillances which have never been performed (i.e., versus surveillances that were "missed").
The Pilgrim TIA dated 1/23/09 (ML083660174) states that "the NRC staffs position is that a missed SR is different-than an SR that was never performed." Some of the key points in the TIA supporting this position are as follows:
- 1) Use of the word "frequency" [in SR 4.0.3] establishes an interval, a period of time, that includes an initial performance-of the SR, and a specified time'period to re-perforrni the SR thereafter, iLe., tod-r*eat the surveillance.
- 2) SRs are performed at frequencies that are more often than the mean-time to failure of particular systems.
Thus, most SRs confirm that SSCs are operable given an operable finding at the previous testing interval.
On 2/24/09 a public meeting was held between the NRC staff and the industry Technical Specification Task Force (TSTF). As discussed in the meeting summary dated 3/24/09 (ML090700535):
"The TSTF began a discussion of SR 3.0.3 [SR 3.0.3 for Standard Technical Specifications (STS) is same as SR 4.0.3 for Salem] and stated that a SR that has never been performed should be treated like a missed SR.
The staff stated that a missed SR is not the same as a never performed SR, therefore SR 3.0.3 can not be, applied to a never performed SR. The TSTF stated, that it does not agree with a December 2008 TIA on the -
subject. The TSTF stated that a TIA from 1992 conflicts with the December 2008 TIA. The staff requested that the TSTF forward a copy of the 1992 TIA to NRC. The TSTF stated that licensees must state why they feel the system will pass a SR in order to ask for an SR 3.0.3 extension for a portion of a system that has never been tested. The staff agreed with the TSTF that a framework for treatment of "never performed SRs" could be developed. The staff stated its belief that this approach was the best way to resolve the differences in position between the staff and the industry on this topic."
By letter dated 5/1/09 (ML090230254), the NRC staff did not accept for review an industry proposal (TSTF-512) that would approve a change to the STS. The change proposed by the TSTF w have revised the
- STS-t~oaestallisb-st nepositionin intepng 5mlq nces that never were perormed as equivalent to surveillance-s-whAesjinte a dvetently exceeded.
In subsequent discussions with the NRC staff, the TSTF indicated that TSTF-512 Would be resulbmitted'to the NRC providing 'additional justification for its position. I talked'to.Carl Schulten in NRR's Tech Spec Branch and he confirmed that the TSTF has not submitted a revised proposal. In addition, Carl confirmed that the current NRC staff position is as stated in the Pilgrim TIA.
Bottom line, PSEG's use of SR 4.0.3 to justify a delay in performing a surveillance that has never been

Need for conference call RE: FEA of Degraded Salem Unit 1 AFW Piping we are looking to do a conference call on Wednesday at 300pm or 330 NLT 400pm to go over what we know about the number of documents that have come in. we think Unit 1 can safely startup in, liht of' repairs'ahd code compliance.
Hdqtrs is reviewing the FEA that will be used to support at Unit 1 past operability determination and root cuase report, not sure when the later two documents will be in but they are not needed for Unit 1 starup.
There is a tech eval on reduced rated pressure to 1275 that was reviewed also in order to support the past operability review. Not'sure how it applies to Unit 2.
Unit 2 current operability and risk assessment (with 1.25 year exposure time on risk) is in on draft and we plan to engage licensee representatives tomorrow on what information supports the Jan 21, 2010 start fo the 1.25 years to the outage next spring in 2011.
Bottom line is looks like back in the construction days, Unit 2 was properly coated but Unit 1 was not. No definitive answers yet as to why, based on desing or documented as left or as found condition back in the 1970s.
We are also trying to deal with the acceptablilty of the Unit 2 operability determination based on an ASME pressure test that was never done and operational information that support flow measurements but may not be considered the alternate ASME unabated flow test per the same code.
With respect to the previous paragraph, a TIA on Pilgirm (ml 083660174) from ITSB seems to accept, partially, an industry position that the test can be deferred if there is a basis that the test will pass - still a violation for which we could issue NCV is green (preferred) or exercise enforcement discretion (least preferred since they were caught on this issue). Not sure the flow information (not test) is as sensitive asthe pressure drop, but.
then again the coating issue seems to be different from Unit 1:. I need to talk to someone in TSbranch and'or Lupold on this. issue, perhaps tomorrow before the conference call - what is a reasonable expectation that the pressure drop test will pass in the spring of next year? When we get a less draft oper det. we can forward it.
