1 FACILITY CHANGE SAFETY ANALYSIS LOG NO. 921 PROPOSED AMENDMENT NO. 155 PAGE 1 i

DESCRIPTION:

Proposed Amendment 155 consists of changes and additions to the Rancho Seco I Technical Specifications regarding radiological effluents to ensure compliance '

with the requirements of 10 CFR 50, Appendix I, as it pertains to effluent monitoring, nearby land use identification, offsite dose calculations, environmental monitoring and limitations on calculated offsite doses. l 1

RFASON FOR CHANGE:

The amendment proposed in this safety analysis are a result cf conclusions '

documented in a July 22,1986, " Staff Evaluation of Rancho Seco Radiological Effluent Technical Specifications and Offsite Dose Calculation Manual Regarding Offsite Doses From Liquid Effluent." This document noted that radionuclides concentrations near the Rancho Seco site resulting from the release of liquid effluents were found to be at levels which could cause the maximum - exposed individual to receive doses well in excess of the dose limits set forth in the 10 CFR 50, Appendix I and 40 CFR 190. Specifically, as a result of the NRC' review, an inconsistency was found between the Lower Limit of Detection (LLD) listed in Table 4.21-1 of the Rancho Seco Technical Specification Surveillance Standards (Section 4.21.1) and Technical Specification Sections (3.17.2 and 4.21.2) relating to 10 CFR 50 Appendix I design objectives. Additional NBC citings for nonconformance to 10 CFR 50 Appendix I were documented in an WRC Region V Inspection Report 86-15 sent'to the District on June 6, 1986. District response to the citings on July 3, 1986 include commitments to submit Technical Spe'cification revisions for conformance with the requirements of 10 CFR 50 Appendix 1. The commitments are addressed in the Proposed Technical Specification Amendment No.155.

EVALUATION AND BASIS FOR SAFETY FINDINGS The following is a discussion of each Technical Specification change. The changes include administrative changes, changes in accordance with the design basis for Rancho Seco and changes that represent additions or upgrade to existing surveillance requirements and limitations. The Tech Spec changes listed in this analysis will be formatted by individual tech spec changes, accompanied by the existing specification, and a discussion of the change. A safety analyais and a no significant hazards consideration will also be included with each change. In addition, attached are copies of the Proposed Amendment No. 155 of the Technical Specifications.
