STPEGS UFSAR 16.0 TECHNICAL SPECIFICATIONS 16.1 TECHNICAL REQUIREMENTS MANUAL The Technical Requirements Manual is a document containing in part information that has been relocated from the Technical Specifications. Relocation of information from the Technical Specifications to the Technical Requirements Manual is based on the requirements of the Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors issued by the NRC in 1993. The Technical Requirements Manual is considered a licensing basis document and as such overall control of the document is governed by applicable station requirements for control of licensing basis documents.
Changes made to the Technical Requirements Manual are governed by the criteria of 10CFR50.59 to determine if changes require approval by the NRC prior to implementation.

STPEGS UFSAR Notes to Table 16.1-1
- Valves isolate on concurrent Containment Phase A isolation and low charging header pressure signals.
- 1. Valves opened only when sample needed.
- 2. Valve could be opened during normal operation, as needed.
- 3. Not subject to Type C Leakage Tests.
- 4. May be opened on an intermittent basis under administrative control.
- 5. These valves are included for table completeness. The requirements of Technical Specification 3/4.6.3 do not apply; instead, the requirements of Technical Specification 3/4.7.1.5 apply to the main steam isolation valves.
- 6. These valves are included for table completeness. The requirements of Technical Specification 3/4.6.3 do not apply; instead, the requirements of Technical Specification 4.6.2.1 apply. Valve stroke times, where specified, will be tested pursuant to Technical Specification 4.0.5.
- 7. These valves are included for table completeness. The requirements of Technical Specification 3/4.6.3 do not apply; instead, the requirements of Technical Specification 3/4.7.1.7 apply to the feedwater isolation valves.
