Transient Combustion Calorimetry (TCC) Project
Research Overview
An extensive set of fire experiments was conducted to support the development of guidance to improve the realism for how transient fires are modeled in Probabilistic Risk Assessments (PRA).This project was a joint collaboration between the Electric Power Research Institute (EPRI) and the U.S. Nuclear Regulatory Commission (NRC) Office of Nuclear Regulatory Research (RES) under a memorandum of understanding on fire research. Building upon the progress of NUREG-2178 (EPRI 3002005578), Refining and Characterizing Heat Release Rates from Electrical Enclosures during Fire (RACHELLE-FIRE), Volume 1, Peak Heat Release Rates and Effect of Obstructed Plume, issued April 2016, on HRRs and obstructed plume, the research continued on other areas related to fire modeling and fire heat release rates (HRRs).
<br>NOTE: There are minor discrepancies between the summary values reported in NUREG-2232 and this FCD database. The method described by NIST TN2077 includes a flow profile shape correction of 1.033 that was not used in the original data analysis. The NUREG-2232 report used a constant value of 13.1 kJ/g oxygen specific energy value, while values reported here use custom energy values for homogeneous specimens. There are additional discrepancies related to the time integration period. The FCD always used the period from ignition to fire out, while the NUREG-2232 report chose test specific time windows. For example, the FCD data from Test041 includes the somewhat artificial peak HRR at 30 min when the fire flares up during extinguishment.
