Regulatory Basis Technical Evaluation K IC of the flywheel material at the normal operating temperature of the flywheel is greater than 165 MPam (150 ksiin). Conformance is demonstrated by an indirect test. Justification is provided to establish the equivalence of fracture toughness in the proposed flywheel material and certain steels (ASME SA-533-B Class 1, ASME SA-508 Class 2, ASME SA-508 Class 3, and ASME SA-516
Grade 65). The RT NDT (nil-ductility reference temperature) of the flywheel materials is determined in accordance with NB-2320 and NB-2330 of the ASME Section III.
-past evaluations have shown that ASME SA-533-B Class1 and SA-508 Classes 2 and 3 materials generally have suitable toughness for typical flywheel applications provided stress concentrations are kept within reasonable limits and the reference temperature RT NDT, determined in accordance with Article NB-2331(a) of Section III of the ASME Code, is at least 50°C (90°F) below the lowest temperature at which operating speed is achieved. For other materials that may be considered for flywheels, the strength and toughness properties should be evaluated and justified for this application.

- Pump Seal Cooling A summary report of the test results for the 22 °F temperature margin has been uploaded to [electronic reading room] ERR, titled "Justification that the APR1400 RCP seals will not exceed the exit temperature specification limit" which is proprietary and not intended to be included in DCD. This report provides
- 1) documentation of the basis for the 22 °F margin and 2) a justification that this margin is applicable to the APR1400 RCP seals. APR1400 RCP specification identifies the same 180 °F limit for the RCP outlet temperature as the System 80 RCP specification and similar loss of component cooling water and/or loss of seal injection tests have been performed on both pumps to sufficiently justify the 22°F margin for the APR1400 RCPs.

Oil Lift SystemOil Collection System Anti-Reverse Rotation Device The only functional requirement of the anti-reverse rotation device for APR1400 RCP Motor is to prevent rotation in the reverse direction without damage when reverse torques are induced as described in Section 5.4.1.2 of DCD. Safety and function of APR1400 are not affected by the type of an anti-reverse rotation device. The document that was reviewed by staff in the non-Chapter 15 audit is actually proprietary as opposed to nonproprietary. Thus the details on the design of the device are vendor specific data; therefore, APR1400 DCD will not incorporate the details on the device. Motor/Pump Sensors

Regulatory Basis Technical Evaluation
When a containment spray (CS) pump requires maintenance or failure during plant MODES 1, 2, 3 and the maintenance or failure require a breach of pressure boundary of the CS pump, the shutdown cooling pumps cannot perform its interchangeable function. Therefore, the affected train will be isolated and the plant will operate under LCO (TS 3.6.6). However, if the CS pump maintenance or failure during plant MODES 1, 2, 3 and the maintenance or failure does not require a pressure boundary breach, the shutdown cooling pumps can perform its interchangeable function. In this case, the plant would not need to operate under LCO.
