Reference:
Letter (PLA -6847)from J. M. Helsel (PPL) to USNRC (Document Control Desk)
Titled "Proposed Relief Request No. JRR -19 to the Third 10-Year lnservice Inspection Program for Susquehanna SES Units 1 and 2," dated April24, 2012.
In the above referenced letter, PPL Susquehanna, LLC (PPL) requested the approval of Relief Request No. 3RR-19 to the Third 10-Year Inservice Inspection Program for Susquehanna SES Units 1 and 2. This Relief Request proposed the approval of ASME Code Case N-702 for use at Susquehanna SES. BWRVIP-108 is the technical basis used to implement the Code Case. Recent operating experience pointed out that not all design assumptions required for the use of BWRVIP-108 have been taken into consideration by the industry. Most of these assumptions are called out under the Assumptions section of the BWRVIP document. One assumption, however, was found in a later section of the BWRVIP-108 document and was not validated prior to submittal of the Relief Request.
The assumption that was missed is that the number of thermal cycles (start-up and shut down) is assumed to be 40 or less over a 40-year plant life. This assumption is too conservative for most of the BWR fleet and Susquehanna exceeded this number well before its 40-year plant life.
The problem of over-conservatism regarding the number of thermal cycles has been discussed with EPRI. EPRI/BWRVIP is working to correct/revise the BWRVIP-108 document so that it reflects a more realistic plant thermal cycle. At this time, there is no timeframe established for revision and publication of a revised BWRVIP-108 document.
Since design assumption on the number of thermal cycles has been exceeded, PPL requests that proposed Relief Request No. 3RR-19 be withdrawn.
