INL presents 2006 RELAP5 International Users Seminar
Idaho National Laboratory will host the 2006 RELAP5 International Users Seminar at the Holiday Inn SunSpree Resort in West Yellowstone, Mont., Aug. 16-18. More than 30 speakers are expected to attend and share analyses using the RELAP5 computer code.
INL (formerly INEEL) began development of the RELAP5 (Reactor Excursion and Leak Analysis Program) over 25 years ago to simulate potential accidents that might occur in light-water reactors. Today, RELAP5 has evolved to include simulations of gas reactor accidents. The program will assist in the development of Generation-IV reactors.
The code's major functions include use as a design tool for modeling existing plants to simulate accidents and for training nuclear power plant operators.
RELAP5 can act much like an airplane pilot flight simulator. Nuclear reactor operators can sit in a mock reactor control room and respond to simulated emergency conditions. The computer simulates plant system reaction to the operators' responses, said Gary Johnsen, RELAP5 program manager.
The code has been successfully marketed and used worldwide. The fully integrated, multidimensional thermal-hydraulic and kinetic modeling capability in the U.S. Department of Energy-developed code can simulate any reactor accident.
Attendees of the seminar will learn from fellow researchers and find out about updates and new applications of RELAP5.
"This year, the seminar will illustrate that the variety of uses for RELAP5 continues to expand," Johnsen said.
