Subject:

RHR Test Procedures

Dear Mr. Kintner:

f ICSB - 3A Residual Heat Removal (RHR) System is a low pressure system that interfaces with the reactor pressure vessel at various locations.

Overpressurization and consequential failures of the RHR system would j

lead to a loss of coolant accident. We asked the applicant to provide l

an analysis to denonstrate that no single failure will result in over-pressurization of the RHR system. The applicant responded by providing an analysis that described the overpressurization protection features for the following RHR lines: RHR suction fran the recirculation system, RHR shutdown return line, RHR steam supply piping, and the RHR head spray line. This description did not verify that the applicant had provided pressure sensor diversity in order to be in conformance with our position (Branch Technical Position ICSB 3).

In response to our question, the applicant stated that redundant sensors are provided for the RHR shutdown cooling pressure interlocks. These interlocks are designed to allow testing when the plant is in operation and as such formal diversity of the sensors and trip units have not been provided. The applicant believes that the accuracy, reliability, and the inherent on-line status nonitoring of the analog transmitter trip unit design obviates the need for diverse pressure sensors, as required to be in conformance with Branch Technical Position ICSB 3.

The staff's position is that the applicant must provide acceptable formal test pro-cedures for these interlocks in order to obviate the need for diverse pressure sensors.

Response

o Formal test procedures will be used as requested.
