Thermal-Hydraulic Process Modeling in Risk Analysis: An Assessment of the Relevant Phenomena (PWR; BWR)

摘要

An assessment of the thermal-hydraulic processes involved in severe light-water-reactor accidents has been conducted as a task in the MELCOR program. The assessment identifies, reviews, and recommends the systems, structures, and thermal-hydraulic phenomena that need to be included in a risk-assessment code. Moreover, the assessment identifies thermal-hydraulic phenomena where the modeling uncertainties are large or where modeling does not currently exist, thus identifying general thermal-hydraulic, risk-assessment code research needs.
