Severa1' years agot th'e staff reviewed the Seabrook Station's Offsite Dose 1

Calculation' Manual (ODCM):as part of.-the staff licensing. rey b activities..

hit that time, the staff 'placed limitations on-the use of the Seabrook Station ODCM. ' The111censee and staff held a meeting on October 16, 1990,. to discuss:

the removal.of:these limitations. The licensee presented:to the staff ~(see-
