Subject:
Virgil C. Summer Nuclear Station Docket No. 50/395 Offsite Dose Calculation Manual
Dear Mr. Denton:
In our letter dated June 4, 1981, the NRC staff was provided the Offsite Dose Calculation Manual (ODCM) for the Virgil C. Summer Nuclear Station.
Page 2.0-10 contained an error which is corrected by the attached page 2.0-10 of this letter. The attached page should be inserted in place of the page presently in the ODCM. Since you were provided ten copies of the ODCM, we are providing you with ten copies of page 2.0-10.
1 If you have any questions, please let us know.
p Very truly yours, 1

2.2.2 Unrestricted Area Dose to Individual I
2.2.2.a For the purpose of sections 3.11.2.2 and 3.11.2.4 of the Technical Specifications, the air dose in unrestricted areas shall be determined as follows:
air dose due to gamma emissions from noble gas D

- where, 3.17 x 10 the fraction of one year per one second X3' relative concentration for unrestricted areas for long term releases 5.3 x 10-6 sec/m in the SE sector
