Expert Evaluation Teams Key Findings

  • Indian Point remains safe.

- A rupture of the 42 Algonquin Incremental Market (AIM) pipeline near Indian Point is unlikely.

- If a rupture occurred, the nuclear power plant and its stored spent fuel would remain protected.

  • The team recommended that the NRC take several actions.

- Entergy should be asked to revisit optimistic assumptions it used in its analyses.

- NRC should consider process updates for peer reviews, inspection support, petition reviews, interagency work, and pipeline analysis.

15 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 AIM Pipeline Unlikely to Fail

  • Construction meets or exceeds DOT requirements for a high-consequence area

- Stronger pipe

- Buried deeper, with concrete slabs, warning tape

- Corrosion protection

- Full weld inspection

- Pressure testing

  • Operator's integrity management program provides for risk assessments, prioritization of ongoing inspections

Plant Safe in the Unlikely Event of a Pipe Rupture

  • Safety-related equipment, spent fuel pools, and dry fuel storage are 2 or more times the "potential impact radius" in DOT regulations
  • Team calculated heat effects - thick-walled important plant structures could withstand a fire burning for ~8 hours 17 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 18 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 17 18 Indian Point 2020 Annual Assessment Meeting

NRC Is Improving its Processes

  • Peer reviews - initial and continued training on updated guidance
  • Inspection support - guidelines for how to ask and answer technical questions
  • 10 CFR 2.206 petition reviews - better decision making, documentation, and independence
  • Pipeline analysis - updated technical guidance, including when/how to do detailed analysis
  • Interagency collaboration - guidance for how to support other agencies' reviews and document interactions 19 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 NRC Inspection of Revised Entergy Safety Analysis 20 Mel Gray, Chief, Engineering Branch 1 Division of Reactor Safety Nuclear Regulatory Commission Region I 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 19 20 Indian Point 2020 Annual Assessment Meeting

NRC Inspection Follow-up of Expert Team Recommendation

  • NRC requested Entergy to revisit optimistic assumptions it used in its 2015 analyses.
  • NRC received revised Entergy analyses and completed inspections in July 2020.
  • NRC completed inspection and issued a report on September 16, 2020 21 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 NRC Inspection Conclusions
  • Indian Point Safety-Related Structures and Equipment Not Affected in the Unlikely Event of an AIM Pipeline Rupture 22 SOCA Rupture Hazards

- Jet fire

- Vapor cloud explosions

- Vapor cloud fire

- Missiles (projectiles from pipe rupture) 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 21 22 Indian Point 2020 Annual Assessment Meeting

NRC Inspection Conclusions (cont.)

  • Entergy revised assumptions that resulted in increased isolation time (8 minutes) and longer pipe length to be isolated (11 miles).
  • Inspectors found assumptions were not used by Entergy in 2015 to determine the impact of pipeline hazards on safety-related equipment.

- Valve closure time discussed in cloud fire hazard analysis but not a factor in conclusions.

23 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 NRC Inspection Conclusions (cont.)

  • Inspectors found Entergy revised their analysis to include additional conservatisms and refinements.

- Jet fire angled towards plant

- Increased flow rate for turbulent jet explosion

- Vapor cloud explosion in tree belt

  • Analyses continued to show safety related equipment is unaffected by AIM pipeline 24 9/22/2020 (888) 391-9420, Passcode: 9660269#, Help *0 23 24 Indian Point 2020 Annual Assessment Meeting
