Palisades Surveillance Capsules Pressure Vessel

  • Purpose of surveillance

- Monitor embrittlement of specific Surveillance steels in specific plants Capsules

- Provides advance information on pressure vessel condition

- Provides data for predictive models

  • Data sources for Palisades

- Initial program

  • 8 irradiation
  • 2 thermal

- Supplemental program

  • 2 irradiation Surveillance Samples

- Other Plants

  • Indian Point 2&3
  • H.B. Robinson 2 1

Palisades Surveillance Data 10CFR50.61

  • Palisades embrittlement Screening Criteria 78 known from 1st capsule pull 93 03 in 1978 83
  • Licensing dates lie well 00 within data (no 98 xx: Date Palisades End of License capsule was extrapolations) pulled &

tested

  • Data follows expected trends Some Technical Details
  • Program complies with ASTM-185(1966) (Years of Reactor Operation)

- 10 CFR 50 Appendix H not in force when Palisades was licensed

- Included high-Cu weld, but not exactly same as Dates in Palisades pressure vessel

  • Palisades supplemented surveillance program to get data on limiting weld

- 2 capsules in Palisades

- 8 capsules in other plants (HBR, IP)

  • 4 capsules remain in Palisades. One more will be pulled before 2031. 2
