Amendment Request for Changes in TS Table 3.3.5.1-1 (CST) and TS 3.10.8.f (TAC NOS. ME0933 and ME0934)

By letter dated March 24, 2009, as supplemented by Letter dated April 24, 2009, you submitted a license amendment request to revise high pressure coolant injection system automatic suction transfer allowable value in TS Table 3.3.5.1-1 and changes to TS 3.10.8.f .

Reactor Systems Branch (SRXB) has identified the areas in which the reviewer requests additional information in order to complete the review of your application, as follows:

1. Please provide the flow analysis as documented in EC-052-1055 to determine the new TS allowable value of 40.5 inches for the CST low level.

2. Please clarify whether the float type level switches are safety-related or not ? If they are not safety-related then justify its operability during transient and accident conditions.

3. Provide operating history of these float type level switches.

Please contact me, if you have any questions and/or need clarifications.
