Availability Notice


This report is an assessment calculation with RELAP5/MOD3.2 – NPA3.4 against a transient that took place in Vandellòs II Nuclear Power Plant on December 2, 1991.

This work is part of the Spanish contribution to the Code Assessment and Maintenance Program (CAMP). Vandellòs II is a member of UNIDAD ELECTRICA, S.A. (UNESA).

Vandellòs II is a 2775 Mwt three loop Westinghouse PWR owned by ENDESA, SA (72%) and IBERDROLA (28%) it is on the Mediterranean coast, near Tarragona (Spain). The commercial Operation began in 1988.

The simulation has been running on a Pentium II 266MHz PC under Windows NT. This version has been tested and results are exactly the same as those obtained with a DECStation 500/200.
