LaSalle LPRM amendment Importance:
High Tim:
I have received a response from the reviewer for the LPRM amendment (MD9414-15) regarding your response to RAIs dated May 11, 2009. I will be forwarding the formal RAI to you by COB on 5/19/09, however, I am providing his response below in case you have any questions or would like to have a telecon to obtain a better understanding of the questions. Please provide your response within 30 days from the date of this e-mail.
Stephen Sands Division of Operating Reactors Clinton & LaSalle Project Manager Licensing Project Branch 3-2 Phone: 301-415-3154 E-mail: Stephen.Sands@nrc.gov The response to RAI SRXB-1 does not provide the requested analysis using decay constants specific to the LPRM detectors used in LSCS. It states that "due to the similarity in the characteristics behavior of the detectors used in Grand Gulf and LSCS, the conclusions presented by Grand Gulf showing the fixed decay constant bounds the specific decay constant is applicable to LSCS." It also indicates that the GE LPRM detectors used in Grand Gulf are NA-250 detectors, while the GE LPRM detectors used in LSCS are NA-300 detectors.
- 1.
Discuss the differences of the NA-250 and NA-300 detectors;
- 2.
Address the effects of differences on the uncertainty analysis, and justify that with the different GE LPRM detectors, the Grand Gulf sensitivity study identifying the effects of the fixed and the specific decay constants on the results of uncertainty analysis is applicable to LSCS.
