Subject:
Peach Bottom Atomic Power Station, Unit 3 Change to the Technical Specifications Bases Regarding the Power / Flow Map
Dear Sir:
The purpose of this letter la to inform you of a change to the Peach Bottom Atomic Power Station (PBAPS), Unit 3 Technical Specifications (TS) Bases, Figure 1.1-1, "APRM Flow Bias Scram Relationship to Normal Operating Conditions." This change is being implemented in accordance with 10 CFR 50.59.
To support a projected long power coastdown for PBAPS, Unit 3 Cycle 10, the power / flow map has been modified to allow a maximum core flow of 110% of rated during power coastdown operations from approximately 70% core thermal power down to the cavitation Interlock Line (at 22% power), as shown in the revised Bases Figure 1.1-1 (Attachment 1).
This power / flow map revision will allow PBAPS, Unit 3 to maintain a higher reactor power during coastdown.
If you have any questions, please contact us.
Very truly yours, 0.
