About this opportunity
This Limited/Sole Source Justification Notice from the Nuclear Regulatory Commission awards a sole source contract to the University of Michigan to complete fabrication and assembly of an advanced two-phase flow instrumentation system and tubular test section. It continues work performed under prior task orders totaling over $1.5 million to develop models for the TRAC RELAP codes by measuring post-critical heat flux conditions and conducting validation testing and experimental data collection. The estimated value of the sole source award made on June 15, 2020 is $753,812 to be completed over a two year period as only the University of Michigan meets the requirements due to the specialized instrumentation and facilities developed for the NRC.
Notice text
JUSTIFICATION FOR OTHER THAN FULL AND OPEN COMPETITION (JOFOC)
Please see attached for full JOFOC related to contract award No. 31310020C0009.
The purpose and objective of this acquisition is to continue the fabrication and assembly of an advanced two-phase flow instrumentation system with the capability to be used to aid in the development of constitutive models for the TRAC RELAP Advanced Computational Engine (TRACE) code and to provide the experimental database necessary for the improvement of the TRACE models for inverted annular through dispersed flow film boiling regimes, which was identified as a high priority near-term development need in the U.S. Nuclear Regulatory Commission’s (NRC), Office of Nuclear Regulatory Research (RES) Thermal-Hydraulic Code Development Plan.
Under this acquisition, the contractor shall continue to acquire the requisite components and assemble the advanced two-phase flow instrumentation system, as well as conduct validation testing. This capability will be used in experimental programs that target models for the Inverted Annular Film Boiling (IAFB) through Dispersed Flow Film Boiling (DFFB) regimes but will continue to be useful for other future experimental programs. Specifically, this advanced instrumentation will provide the first quantitative insights into the flow topology and subchannel-averaged void fractions for these post-Critical Heat Flux (CHF) regimes.
A further objective of this acquisition is the performance of steady-state low-quality film boiling experiments in a tubular test section. A major component of this experimental program is the utilization of the X-ray radiography system that has already been nearly completed in the instrumentation portion of the effort. This advanced two-phase instrumentation system will provide not only for the accurate measurement of the void fraction during post-CHF conditions but also provide information on the flow topology such as the size and shape of the liquid slugs in the Inverted Slug Film Boiling (ISFB) regime.
Awarded contract 31310020C0009 to unknown vendor for unknown amount on 2020-06-15.
