First-Ever Asian MELCOR User Group Meeting

The first-ever Asian MELCOR User Group Meeting was held in Daejeon, South Korea, from October 13–17. MELCOR (Methods for Estimation of Leakages and Consequences of Releases) is a fully integrated, engineering-level computer code whose primary purpose is to model severe-accident progression in light-water-reactor (LWR) nuclear power plants. Sandia developed MELCOR for the US Nuclear Regulatory […]

Paper Describing Lessons Learned from Fukushima Receives “Outstanding Paper Award”

Jeff Cardoni (in the Severe Accident Analysis Dept.) presented the paper “MELCOR Simulations of the Severe Accident at the Fukushima 1F3 Reactor” at the 2012 ANS Winter Meeting and Nuclear Technology Expo, which held an embedded topical meeting called “International Meeting on Severe Accident Assessment and Management: Lessons Learned From Fukushima Daiichi.” on November 11–15, […]

Cyber-Based Vulnerability Assessments

On August 21, 2012, in

Digital Instrument and Control (I&C) is an integral part of the nuclear power industry in the United States. I&C systems monitor the safe, reliable and secure generation and delivery of electricity and could have potential cyber vulnerabilities. At Sandia National Laboratories, cyber-based vulnerability assessments are conducted on multiple I&C platforms deployed in the nuclear industry […]
