Report Title:
Computer codes for small-break loss-of-coolant accidents - a Nordic assessment
Activity Acronym:
SÄK-3
Authors:
Ole Rathmann (edt.)
Abstract:
An assessment of computer codes for analysis of small-break
LOCA's is performed.
The work comprises the American systems codes TRAC/PF1,
RELAP5/MOD1, RELAP5/MOD2 and the Finnish fast-running code
SMABRE which are assessed theoretically and by comparative
calculations of five small-break LOCA experiments. On this
basis comparisons are made of the advantages and drawbacks of
each code in order to conclude which should be selected for
small-break LOCA analysis, including a recommendation of necessary
modifications.
