Subject:
Additional Information - License Amendment Request No. 315, Application of Alternative Source Term (TAC No. MC6519)
References:
(1) AmerGen letter to USNRC, License Amendment Request No. 315-Application of Alternative Source Term, dated March 28, 2005.
(2) AmerGen letter to USNRC, Additional Information - License Amendment Request No. 315 , Application of Alternative Source Term (TAC No.
MC6519), dated March 23, 2007.
This letter provides the additional information discussed in a conference call held on March 28, 2007, regarding Oyster Creek License Amendment Request No. 315, submitted in Reference 1, and the control room occupancy assumed for the revised radiological dose analysis supporting the Oyster Creek application for alternative source term submitted in Reference 2.
The occupancy factor used in the Oyster Creek control room post-LOCA radiological analysis (Reference 2) is assumed to be 1.O for the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and 0.25 for the remainder of the 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br /> of the postulated event. These values are determined to be conservative for the most exposed operator following the Oyster Creek shift rotation schedule. Oyster Creek operates with 5 crews rotating 8-hour shifts. For the case of the maximum exposed operator, it is assumed that the design basis accident occurs during the day shift, with the shift operator expected to work for a 24-hour period. It is conservatively assumed that he works on Day 2, and continues his scheduled day shift rotation through day 5 of the accident. After this rotation, he is scheduled off for the next 7 days. He will then work 2 days of day shift, followed by 3 days off, 7 days of afternoon shift, 2 days off, and then 4 night shifts to complete his 30 days.
For all scheduled days (other than the first 24-hour day), it is assumed that he works 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> per day to account for shift turnover. This operator will be in the control room for a total of 177 hours0.00205 days <br />0.0492 hours <br />2.926587e-4 weeks <br />6.73485e-5 months <br /> over the 30-day period. This period of 177 hours0.00205 days <br />0.0492 hours <br />2.926587e-4 weeks <br />6.73485e-5 months <br /> of work over the 720-hour period equates to a fractional value of occupancy of 0.245 (177/720 = 0.245). It is noted that the total hours worked over the 696 hours0.00806 days <br />0.193 hours <br />0.00115 weeks <br />2.64828e-4 months <br /> following the initial 24-hour occupancy is 153 hours0.00177 days <br />0.0425 hours <br />2.529762e-4 weeks <br />5.82165e-5 months <br />, which yields a lower occupancy value of 0.22 ((17x9)/(720-24) = 0.22). Other shift rotations for the
U.S. Nuclear Regulatory Commission March 28,2007 Page 2 30-day period were reviewed. The other occupancy factors calculated yield lower values than the case described above. Therefore, the value of 0.25 used after the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is conservative.
No new regulatory commitments are established by this submittal. If any additional information is needed, please contact David J. Distel at (610) 765-5517.
I declare under penalty of perjury that the foregoing is true and correct. Executed on the 28'h day of March, 2007.
