December 30, 2020 MEMORANDUM TO: Joseph E. Donoghue, Director Division of Safety Systems Office of Nuclear Reactor Regulation Signed by Case, Michael FROM: Michael J. Case, Director on 12/30/20 Division of Systems Analysis Office of Nuclear Regulatory Research
SUBJECT:
DELIVERY OF PARTIAL DELIVERABLE ASSOSIATED WITH THE TRACE CODE MAINTENANCE, PLANT MODEL MAINTENANCE, AND PLANT MODEL DEVELOPMENT TO SUPPORT LICENSING ACTIONS AND EMERGENT TECHNIAL ISSUES USER NEED By Work Request dated July 26, 2019 (ML19143A320), the Office of Nuclear Reactor Regulation (NRR) requested that the Office of Nuclear Regulatory Research (RES) perform the necessary TRACE code plant-model development and TRACE coding support and maintenance to deliver an up-to-date TRACE code and twelve compatible TRACE plant models able to perform a series of plant transients and loss-of-coolant accidents (LOCAs). This memorandum announces the completion of the first of the twelve TRACE plant models, Oconee, and the release of a new TRACE patch version, Patch 6, in accordance with the user need that RES tracks under the identifier NRR-2019-011.
The Oconee deliverable package (ADAMS Accession No. ML20357B092) includes a collection of TRACE models, a Symbolic Nuclear Analysis Package (SNAP) Engineering Template, two Purdue Advanced Reactor Core Simulator (PARCS) models, steady-state cycle depletion results used in the PARCS models, a calculation notebook, and an analysis report. The collection of TRACE models include a base steady-state model at nominal conditions, a large-break LOCA (LBLOCA) model, a small-break LOCA (SBLOCA) model, and models to simulate each of the following transients: loss-of-flow (locked rotor), rod-ejection accident, turbine trip, and steam line break. The two included PARCS models are to be coupled with the transient TRACE models to perform the transient simulations. The SNAP Engineering Template is the tool used to execute the LOCA and transient simulations. The calculation notebook documents the details of the TRACE model input, and the analysis report describes the model adjustments and the results from the LOCA and transient simulations.
All simulations performed with the Oconee TRACE and PARCS models were performed using TRACE Patch 6. Linux and Windows executables for Patch 6, along with draft versions of the corresponding documentation, have been placed in the Codes folder on the RES High-Performance Computing govCloud (RESGC). The final versions of the code documentation will be delivered by March 31, 2021, in accordance with the TRACE patch-release milestone.
