| Agenda
| |
| * Description
| |
| * Proposed Technical Specification (TS) Changes

| |
| * Precedents
| |
| * Submittal Timeline 2
| |
| | |
| Description
| |
| * Technical Specification Task Force (TSTF)-487-A relocates Reactor Coolant System (RCS) Departure from Nucleate Boiling (DNB) parameters from the TS to the Core Operating Limits Report (COLR)
| |
| * Parameters include RCS pressure, temperature, and total flow rate
| |
| * Changes are consistent with the Standard Technical Specifications (NUREG-1432, Rev. 5) and no changes are made to the actual limits
| |
| * Submittal will be consistent with the model application in the federal register (72 FR 31108) 3
