Subject:

Limerick Generating Station, Units l&2 Start-Up Test (SUT)-38 Pro'cedures and System Review Branch (PSRB)

Reference:

PECO and NRC telecon dated March 1, 1984 between M. J. Campanone and W. Long (NRC) and C. R. Endriss, V. Nilekni (Bechtel) and R. J. Stipcevich (PECO).

File: GOVT l-1 (NRC)

Dear Mr. Schwencer:

As discussed in the reference telecon with the Procedures and Systems Branch Reviewer, start-up test (SUT)-38, "MSIV Leakage Control System (MSIV-LGS)

Performance Verification", is being deleted from the FSAR.

We will incorporate the functional testing requirements for the MSIV-LGS in pre-op test 83.1, " Main Steam System".

Pre-op test 83.1 will functionally test the MSIV-LGS using compressed air instead of nuclear steam thereby avoiding the potential for contaminating primary containment, the steam tunnel and standby gas treatment system filters. This change will keep radiation exposure to personnel as low as reasonably achievable.

The PSRB branch reviewer, W. Long, concurred with this change and in fact stated that, with this approach, Limerick would be consistent with what other similar plants have done.

(STP-37) Main Steam System and Turbine Performance and Plant Dynamic Response Verification (Formerly SUT-37)

Test Obiectives - The test objectives are to demonstrate (1) the satisfactory performance of the main steam system and.the main

, turbine; and (2) that the dynamic response of the plant to the design load swings, including step and ramp ' changes, is in '

accordance with design.

. Prerequisites - Fuel loading is completed, and power ascension testing is in progress.

Test Method - Reactor power is brought to 25, 50, 75 and 100 percent to verify operability and design performance requirements i of the main steam system and main turbine. Design step and ramp load changes are induced at each power level to verify plant dynamic response.

~

Acceptance Criteria - The main steam system operates properly at the specified power levels. The main turbine operates within

! specifred limits throughout the full power range. The dynamic

. response of the plant to design load swings is within specified limits.
