Document Control DeskPage 2The purpose of this letter is to provide the NRC with the MNGP cycle 27 SupplementalReload Licensing Report (SRLR) applicable to MELLLA+ conditions and evaluationsand to provide a response to an NRC Request for Additional Information (RAI).Enclosure 1 to this letter provides the MNGP cycle 27 SRLR applicable to MELLLA+conditions and evaluations. The cycle 27 SRLR is being submitted to the NRC to fulfillthe requirements of the MELLLA+ topical report (Reference 2), Limitation and Condition12.4, which specifies that the SRLR for the initial MELLLA+ implementation cycle shallbe submitted for NRC staff confirmation.The SRLR supports the licensing work performed for the MNGP MELLLA+ license.This reload design was initiated prior to the PRIME transition commitment to utilizePRIME for reload analyses. The cycle-specific reload analyses are based on GESTR-M,with one exception, and the peak clad temperature (PCT) impact of PRIME wasevaluated as part of 10 CFR 50.46 Error Notification 2012-01. The one exception is theDetect and Suppress Solution -Confirmation Density (DSS-CD) Backup StabilityProtection (BSP) analysis, which was performed using PRIME. The use of PRIME forthe DSS-CD BSP analysis is consistent with NEDO-33173 Supplement 4-A, Rev. 1,"Implementation of PRIME Models and Data in Downstream Methods," November 2012.Enclosure 2 provides a report from General Electric -Hitachi (GEH) letter,GE-MNGP-AEP-3306, "GEH Response to MELLLA+ EICB RAI," which provides aresponse to the NRC's RAI (Reference 3).
