LOFT Fuel-Rod-Transient DNB (Departure Nucleate Boiling) Probability Density Function Studies

摘要

Significantly improved DNB safety margins were calculated for LOFT reactor fuel rods by use of probability density functions (PDF) for transient MDNBR. Applicability and sensitivity studies determined that the PDF and resulting nominal MDNBR limits are stable, applicable over a wide range of potential input parameters, and applicable to most transients.
