Description
The U.S. Nuclear Regulatory Commission (NRC) proposes to enter into a non-competitive purchase order with the University of Illinois at Urbana-Champaign (UIUC) (364 Henry Administration Bldg., Urbana, IL 61801) for the project entitled, "Investigation of TRACE Closure Laws Accuracy in Modeling BWR ATWS in MELLLA+ Domain using Integral Uncertainty Quantification Methods". The acquisition is conducted under the authority of Federal Acquisition Regulation (FAR) 13.106-1(b) which provides that contracting officers may solicit from one source if the contracting officer determines that the circumstances of the contract action deem only one source reasonably available (e.g., urgency, exclusive licensing agreements, brand-name or industrial mobilization). The designated North American Industry Classification System (NAICS) Code is 541715, Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology). The proposed period of performance is date of award through September 30, 2021.
The purpose of this acquisition is to investigate TRAC/RELAP Advanced Computational Engine (TRACE) modeling capabilities of unstable conditions that could arise during postulated anticipated transients without SCRAM (ATWS) for boiling water reactors (BWRs). The unstable conditions are postulated to occur for BWRs operating at high power and low flow conditions in the expanded MELLLA+ [Maximum Extended Load Line Limit Analysis plus] operating domain. The work will identify the TRACE closure laws responsible for discrepancies in modeling of this phenomenon. The analysis will be based on experiments that had been conducted at a high pressure thermal-hydraulic experimental facility. The identification of the models will be performed based on rigorous sensitivity study using state-of-the...
