Ref:
- 1) USNRC RG 1.21 Revision 1, June, 1974, Measuring, Evaluating, And Reporting Radioactivity In Solid Vastes And Releases Of Radioactive Materials In Liquid And Gaseous Effluents From Light-Vater-cooled Nuclear Power Plants
- 2) Beaver Valley Power Station Unit 1 And Unit 2 Technical Specifications 6.9.1.12 and 6.9.1.13, Semi-Annual Radioactive Effluent Release Report Gentlemen:
The Semi-Annual Radioactive Effluent Release Report is hereby submitted in accordance with the requirements of Technical Specifications 6.9.1.12 and 6.9.1.13 for Beaver Valley Power Station Unit i license DPR-66 and Beaver Valley Power Station Unit 2 license NPF-73.
This report contains the information require! by USNRC Regulatory Guide 1.21 Revision 1 and the Technical Specifications.
This report is considered a single submittal for the two unit site. This report combines those sections that are common to both units at the site.
However, where the two units have separate radvaste systems, the report does specify the releases of radioactive material from each unit.
In reference to this, Unit I and Unit 2 have shared radvaste systems for gaseous elevated releases and for liquid releases. The report format is summarized on the index.
There was one abnormal gaseous release during the report period, it occurred on March 29, 1993.
Although the release was unplanned, it was determined to be within the Radiological Effluent Technical Specification /
Offsite Dose Calculation Manual Release Limits, and no reportings vere required per 10 CFR 50.72, 10 CFR 50.73, 10 CFR 20.403, 10 CFR 20.405, and 40 CFR 302.6.
The release involved the loss of 262 cubic feet of gas from the Unit 1 Pressurizer Relief Tank to the Reactor Containment Building.
This release occurred while performing a planned purge of the Unit 1 Reactor Containment atmosphere in preparation for Unit l's 9th Refueling Outage. The unplanned discharge activity of 10.8 curies was comprised of 95% Xe-133 and 5% of Kr-85, Xe-131m, Xe-133m, Xe-135, and tritium.
