This will affect the RTD response time, which is used in the OTT tripfunction. The OTT trip initiates automatic protective actions to mitigate the consequences ofthe following events, and therefore would be affected by the change in RTD response time:1.

D. C. Cook Unit 1: Draft Question re. Propsoed RTD Bypass Amendment(TAC MD2106)Michael, Joe:
This is regarding your 5/31/06 application for amendment. We have developed the followingdraft question, and would like to discuss it with you in a conference call: The amendment request involves the removal of the resistance temperature detector (RTD)bypass manifolds. This will affect the RTD response time, which is used in the OTT tripfunction. The OTT trip initiates automatic protective actions to mitigate the consequences ofthe following events, and therefore would be affected by the change in RTD response time:1. Loss of electrical load/turbine trip2. Uncontrolled rod cluster control assembly (RCCA) bank withdrawal at power
- 3. Chemical Volume Control System (CVCS) malfunction that results in a decrease in the boron concentration in the reactor coolant
- 4. Inadvertent opening of a pressurizer safety or relief valveFor each event, show that OTT will continue to provide adequate protection from departurefrom nucleate boiling following the requested change in RTD response time.This e-mail aims solely to prepare you and others for the requested conference call. Thise-mail does not convey a formal NRC staff position, and does not formally request for additional information. We will discuss disposition of this question in the requestedconference call.Peter S.
