The purpose of this document is to record the technical evaluation of the Limiting Condition for Operation (LCO) described in the Plutonium Finishing Plant (PFP) Operational Safety Requirements, WHC-SD-CP-OSR- 010, Rev. 0. Kay 1994, Section 3.2.3, `Supply Ventilation System Seismic Shutdown.` This document, with its appendices, provides the following: 1. The system functional requirements for determining system operability (Section 3). 2. Evaluations of equipment to determine the safety boundary for the system (Section 4). 3. A list of annotated drawings which show the safety envelope boundaries (Appendix C). 4. A list of the safety envelope equipment (Appendix B). 5. Functional requirements for the individual safety envelope equipment, including appropriate setpoints and process parameters (Section 4.1). 6. A list of the operational, maintenance and surveillance procedures necessary to operate and maintain the system equipment within the safety envelope (Sections 5 and 6 and Appendix A)
