Subject:
Draft RAI for proposed amendment - RTD Modification for DC Cook 1 (TAC MD2106)
Joe:
The NRR technical staff (Christopher Somers and Sam Miranda) reviewed the TS changes proposed in your letter dated May 31, 2006. We need additional information to complete our review.
The application for amendment details a physical modification of the resistance temperature detector loop. It stated that "the individual components of the OTT and OPT reactor trip response time assumed in the non-LOCA analyses will be altered. Provide assurance that the OTT trip, as modified by the proposed RTD bypass elimination, will protect against an inadvertent opening of a pressurizer safety or relief valve.
This e-mail prepares you and others for a conference call, if you so desire one, before we make a final disposition of this draft RAI. This e-mail does not formally state an NRC staff position, nor does it formally request for information.
