.- ENCLOSURE I

I REQUEST FOR ADDITIONAL INFORMATION CONCERNING PROPOSED CHANGES IN THE LIQUID EFFLUENT TECHNICAL SPECIFICATIONS FOR CATAWBA 1 AND 2 RADIATION PROTECTION BRANCH i

1. By letter dated June 12, 1987 Duke Power Company proposed.to change the Technical Specifications for Catawba Units 1 and 2 so slightly radioactive  !

liquid from the turbine and auxiliary building sumps can be rellased through the Conventional Wastewater Treatment System. Duke indicated that these releases would be in accordance with Technical Specifications J 3/4.11.1.1 (on instantaneous concentration) and 3/4.11.1.2 (on calculated dose). The proposed lower limit of detection (LLD) of the monitor, l however, is 500 pCi/L and it is not evident that this is adequate. l The proposed LLD seems questionable because: (1) to comply with TS 3/4.11.1.2, the average concentration at the. release point must be less '

i than 1.2 pCi/L dose equivalent Cs-134; (2) to show compliance where there I is more than one source and/or where concentrations vary, the LLD must be well below the allowable average concentration; and (3) it is not clear that either the conventional wastewater system er the normal discharge path for radioactive liquids will always provide sufficient dilution to justify reliance on monitoring at the proposed LLD. To resolve this uncertainty Duke should specify how these releases are to be made and provide an analysis showing the LLD to be adequate (or proposing an adequate LLD).

2. The possible use of the conventional wastewater treatment syste:a as a second release point for radioactive liquids raises the question of how doses are to be calculated to show compliance with TS 3/4.11.1.1. Since the dose criteria were established to limit releases rather than to 1 increase the number of release points, Duke should commit to adding the release via the conventional wastewater treatment system to the release via the normal radioactive liquid release point when calculating doses to show compliance with TS 3/4.11.1.2.
