Letter from NuScale Power, LLC to Nuclear Regulatory Commission, NuScale Power, LLC Submittal of the NuScale Standard Plant Design Certification Application, Revision 3, dated August 22, 2019 (ML19241A315)

During an August 27, 2019 public teleconference with NRC Project Manager and NRC reviewers, NuScale Power, LLC (NuScale) discussed potential updates to Final Safety Analysis Report (FSAR),

Section 14.2 Initial Plant Test Program. As a result of this discussion, NuScale changed the Section 14.2. The Enclosure to this letter provides a mark-up of the FSAR pages incorporating revisions to Section 14.2, in redline/strikeout format. NuScale will include this change as part of a future revision to the NuScale Design Certification Application.

The enclosure to this letter is the nonproprietary version of the changes to NuScale Final Safety Analysis Report, Section 14.2, Initial Plant Test Program, Table 14.2-2, Pool Cleanup Systems Test

  1. 2, and Table 14.2-50, Module Assembly Equipment Test #50.

This letter makes no regulatory commitments or revisions to any existing regulatory commitments.

If you have any questions, please feel free to contact Nadja Joergensen at 541-452-7338 or at njoergensen@nusclepower.com.

NuScale Final Safety Analysis Report Initial Plant Test Program is applicable to the system) unless the preoperational test verifies an ITAAC. The component tests are standardized to provide the same level of test detail across all systems. This graded approach does not affect system-level tests which require integrated system operation. The standardized component tests are:

  • Remote operation of equipment.
  • Manual control of variable-speed pump or fan.
  • Automatic start of standby pump or fan.
  • Automatic operation of pump recirculation valve.
  • Remote operation of valve or damper.
  • Valve or damper fails to its safe position on loss of air.
  • Valve or damper fails to its safe position on loss of electrical power to its solenoid.
  • Damper or fan responds to fire or smoke alarm.
  • Equipment response to automatic signals to protect plant equipment.
  • Automatic operation of tank or basin level control valve.
  • Automatic bus transfer via bus tie breaker.
  • System instrument calibration.
  • Each instrument is monitored in the MCR and the remote shutdown station (RSS), if the signal is designed to be displayed in the RSS. (Test not required if the instrument calibration verified the MCR and RSS display.)

14.2.3.3 Testing of First-of-a-Kind Design Features RAI 03.09.02-10, RAI 14.02-1 First-of-a-kind (FOAK) tests are new, unique, or special tests used to verify design features that are being reviewed for the first time by the NRC. The NuScale Power Plant contains design features which are new and unique and have not been tested previously; therefore, testing of these design features is treated as FOAK. For the FOAK tests, the testing frequency is specified in the test abstract. The NuScale comprehensive vibration assessment program (CVAP) is a FOAK program. The program is implemented consistent with the requirements of the NuScale Comprehensive Vibration Assessment Program Technical Report", TR-0716-50439, and the NuScale Comprehensive Vibration Assessment Program Measurement and Inspection Plan Technical Report, TR-0918-60894. The CVAP is addressed in Section 3.9.2.

RAI 03.09.02-10, RAI 14.02-1, RAI 14.03-3 The following ITP test abstracts describe the on-site CVAP testing of FOAK design features:

The pool cleanup system (PCUS) is described in Section 9.1.3.2.3 and the functions verified by this test are:

System Function System Function Categorization Function Verified by Test #

1. The spent fuel pool cooling system nonsafety-related Test #2-1 (SFPCS) supports the PCUS by providing spent fuel pool water for purification of the ultimate heat sink (UHS).
2. The reactor pool cooling system nonsafety-related Test #2-1 (RPCS) supports the PCUS by providing reactor pool water for purification of the UHS.
3. The pool surge control system (PSCS) nonsafety-related Component level tests supports the PCUS by providing Pool Surge Control System Test #4-1 water from the dry dock for UHS inventory control.
4. The PCUS supports the PSCS, RPCS, nonsafety-related Component level tests and SFPCS by providing a flowpath to cross-connect the PSCS, RPCS, and SFPCS.
