- Mohsin Reza, Neutronics Engineer
- John Adams, Safety Analysis Supervisor
- Jeff Moore, Safety Analysis Engineer
- Jim Hoerner, Thermal Mechanics Engineer 3 CEA Recovery Time Improvement
Background
- CCNPP has observed a trend with the current configuration where a single-point vulnerability caused a Control Element Assembly (CEA) to become misaligned in the core at full power.
- CCNPP is replacing the current CEA drive system on both Units (2023/2024)
- Under the current TS, if a CEA is misaligned > 15 inches in Modes 1 and 2, the site is required to:
- Restore CEA in accordance with the Core Operating Limits Report (COLR) (0 to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> based on FrT) OR
- Reduce Reactor Thermal Power (RTP) to < 70% within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> AND
- Restore CEA within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, OR
- Be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
4 CEA Recovery Time Improvement
Current CCNPP Technical Specifications 5 CEA Recovery Time Improvement
Proposed Change to TS 3.1.4
- Under the proposed TS change, if a CEA is misaligned > 15 inches in Modes 1 and 2, the site is required to:
- Restore CEA in accordance with the COLR OR
- Reduce RTP to < 60% within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> AND
- Restore CEA within 7 days
- Be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
6 CEA Recovery Time Improvement
Associated LAR and Engineering Modifications
- The recently withdrawn Studsvik LAR is not associated/linked with this planned LAR
- Constellation is planning to separately submit documentation to meet Generic Letter 83-11 demonstration / verification requirements (not under 50.90)
- The Studsvik Topical Report SSP-14-P01/028-TR is NOT an input in the Framatome analysis 7 CEA Recovery Time Improvement
Associated LAR and Engineering Modifications
- The GARDEL Engineering Modification will
- Install new core monitoring software
- Be completed in December 2023
- Constellation is strategically submitting the CEA Recovery Time Improvement Project LAR in 4Q2022 to permit implementation shortly after the GARDEL Engineering Modification is complete to provide the maximum misaligned CEA recovery benefit
- COLR change will be implemented after GARDEL is installed
- TS Changes will be implemented during startup from CCNPP U1 2024 Spring RFO (mid-cycle U2) 8 CEA Recovery Time Improvement
Submittal Schedule Action Date
- Submittal of CEA Recovery Time Improvement Project LAR 4Q2022
- CCNPP replacing the CEA drive system on Unit 2 02/2023 CCNPP U2 Spring RFO
- GARDEL Engineering Modification Complete 12/2023
- Projected NRC approval of CEA Recovery Time Improvement 4Q2023 Project LAR
- CCNPP replacing the CEA drive system on Unit 1 and 02/2024 CCNPP U1 Spring CEA Recovery Time Improvement Project LAR Implementation RFO for both CCNPP Units 9 CEA Recovery Time Improvement
End of Public Portion 10 CEA Recovery Time Improvement
