.i l1. DLC/BVPS-2 is using the term "SPDS" not "PSSD."

' described in Section 7 of the FSAR.

5. The OTSC.is not a part of the licensing submittal for the SPDS. l

.6. V&V ' results will be available for NRC audit during Post-Imple-mentation Review. .DLC is requesting a post-implement at ion

- review of BVPS-2's SPDS by the NRC three months prior to fuel

load versus the ' scheduled post ' implementation review per Refer-encez(a). This.is'due to the recent six-month delay not ifica-tion for commercial operation for BVPS-2.
