-MEASUREMENT UNCERTAINTY RECAPTURE POWER UPRATE RAI 1: Recalculate the Reactor Vessel fluence values provided in Section IV 5 of Attachment 2 of Calvert Cliffs Measurement Uncertainty Recapture Evaluation LAR ofAugust 29,2008 in accordance with the guidance of Regulatory Guide 1.99.CCNPP Response: The below values were calculated in accordance with guidance of Regulatory Guide 1.99: Unit 1 Fluence Unit 1 Fluence Unit 2 Fluence Unit 2 Fluence 1.4% Power 1.4% Power Current UpaeCurrent Urt Uprate Uprate Vessel Clad 5.09E+19 5.11E+19 5.74E+19 5.79E+19 Interface 1/4 T Location 3.04E+19 3.05E+19 3.42E+19 3.45E+19 3/4 T Location 1.08E+19 1.08E+19 1.22E+19 1.23E+19 Note that this information may be different than the data used for reactor vessel surveillance capsule withdrawals and is subject to evaluation and re-calculation as necessary whenever new information is obtained (i.e., data obtained from future surveillance capsule withdrawals).
RAI 2: State whether Calvert Cliffs is in compliance with Regulatory Guide 1.190 in regards to the determination of reactor vessel neutonfluence values used in this submittal.
CCNPP Response: The determination of reactor vessel neutron fluence values was performed using methodologies that are consistent with the overall intent, although not the specific details, of Regulatory Guide 1.190 (Reference 1).For Calvert Cliffs Unit 1, the current dosimetry, neutron fluence, and radiation embrittlement results were documented in Babcock & Wilcox (B&W) Report BAW-2160 (Reference
- 3) and submitted to the Nuclear Regulatory Commission (NRC) via the correspondence of Reference
- 4. For Calvert Cliffs Unit 2, the current dosimetry, neutron fluence, and radiation embrittlement results were documented in B&W Report BAW-2199 (Reference
- 5) and submitted to the NRC via the correspondence of Reference 6.The surveillance capsule withdrawal schedules were determined via American Society for Testing and Materials (ASTM) E185 (Reference 7), while the neutron fast and total fluxes, neutron fast and total fluences, and the displacement per atom values of the surveillance specimens and the corresponding values for the reactor vessel were determined in accordance with the guidelines in ASTM E482 (Reference
- 8) and Regulatory Guide 1.99 (Reference 2). The DOT4 discrete ordinates transport code was used in R-theta (midplane) and R-Z coordinates using a P 3 expansion of the cross-section transfer matrix and flux moments, an S 8 r-theta quadrature, and a multi-group energy structure above 0.1 eV. The methodology employs absolute fluence calculations with documented and verified plant-specific data, local fission isotopics, and temperature-dependent water densities.
Note that Regulatory Guide 1.190 was issued seven years after Calvert Cliffs last surveillance capsule analysis.
Calvert Cliffs Nuclear Power Plant Units 1 and 2 surveillance capsules will be extracted in 2010 ATTACHMENT (1)RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION
