Dear Mr. Keppler:
This is a response to IE Bulletin 80-16 concerning " Potential Misapplication of Rosemount, Inc., Models 1151 and 1152 Pressure Transmitters with either "A" or "D" Output Codes."
Toledo Edison has determined that twelve such transmitters have been installed at the Davis-Besse Nuclear Power Station Unit 1.
All of these transmitters are utilized in safety related applications. These include:
a) Eight Model ll52DPSA92PB transmitters in the Steam and Feedwater Rupture Control System (Nos. LTSP9A6 to A9 and LTSP9B6 to B9).
b) Four Model ll52GP9A92T0010PB Reactor Coolant System pressure transmitters for the Reactor Protection System.
(Nos. PT RC2Al, 2A2, 2B1 and 2B2).
Toledo Edison's investigation has revealed that thcsc transmitters cannot be exposed to input pressures that could result in anomalous output signals during normal operation, anticipated transients or design basis accidents.
As a result, no corrective actions are required. This completed Toledo Edison's action on this Bulletin.
Very truly yours, 79-RPC/TJM/aa ec:
