Palisades: Request for telecon re. Alternative Source Term (TAC MD3087)

Jim:

Our reviewer, Leta Brown, is requesting a telecon with you and others. This relates to your alternative source term license amendment request and a drawing that was part of the 06/15/2007 response (Accession No. ML071700698) to our request for additional information.

It appears to Leta that you may have used (perhaps unintentionally) two scales when putting some "dots" on this "information only" drawing and she would like to discuss the drawing with you. The following paragraph contains specifics:

We agree that the Plant Area Plan drawing is for approximation only and that the scale for postulated releases to Intakes 1 and 2 is about 1 inch = 50 feet. However, if we apply the 1 inch = 50 feet scale for the releases to Intake 3, the distances are underestimated when compared with the values provided in Table 1.8.1-1 of Enclosure 4 of the submittal dated September 25, 2006. Note that if the distances were underestimated, this would result in an underestimate of the atmospheric dispersion factors (X/Q values) and resultant doses. We understand that Plant Area Plan drawing is for information only and was probably not used to generate the distances in Table 1.8.1-1.

This e-mail does not formally request for additional information, and does not convey a formal NRC staff position. The sole purpose of this e-mail is to prepare you and others for the requested relecon. Please contact me to arrange the requested telecon.
