Availability Notice


The analysis group of Almaraz Nuclear Power Plant has developed a model of the plant with RELAP 5 / MOD. 2 / 36:04. This model is the result of the work-experience on the code RELAP 5 / MOD. 1 / that was the standar code during the period 1.984/1.989. Different solutions were adopted in the network to adecuate the model to RELAP 5 MOD. 2 Computer Code.

This transient was selected for ICAP because it presents an experience with the same transient calculated with RELAP 5 / MOD. 1 / CY 29 computer code. The comparison between both analysis will be interesting.
