_. -REVISION 9-This revision incorporates SONGS 3 into the ODCM. It includes the addition of Radiation Monitors 3RT-7821- (pages 1-7 and 1-10), 3RT-7821

>(page 1-11), 3RT-7818 and 7870-1 (page 2-3) and 3RT-7804 (page 2-4);

'their. calibration constants; (page 1-13 and 2-10); Flow

-Indicator 3FI-3772; and the. administrative value to account for simultaneous: releases from both~ SONGS 2 and SONGS 3 (pages 2-3, 2-4 and 2-5). In addition, this revision added a statement which had been removed in a previous--revision (page 2-2, 2-4 and 2-6) and renumbered pages for text:(page'i) and Tables (page-111).

The. calculational methodology for; Unit 3 is identical to that of Unit 2 Tand uses the same conservative assumptions, _ therefore the changes do K not reduce the accuracy or reliability of dose calculations or setpoint determinations.

This revision was presented and accepted by the Onsite Review Committee on November.9, 1982.
