Heavy water coolant flows inside the channels which are all immersed inside the moderator tank. Each assembly is placed inside an individual Zircaloy coolant channel.

Its 451 fuel assemblies are 6.03m high and each composed of 37 Zircaloy clad fuel rods. Atucha 2 is a PHWR, cooled and moderated by heavy water, presently in commissioning process. Main variables like cladding temperature, level in coolant channels, hydrogen production and core heatup delay have been analyzed.Ĭalculations show that the countermeasure is in general terms equally effective, if started up to 3 hours after the initiation of the event and that a delay of around 6.hs is obtained for the cases without water replenishment to the feedwater tank.Ī severe accident assessment was performed for the Atucha 2 Nuclear Power Plant in Argentina. For each injection time initiation, two cases were calculated: one taking into account initial feedwater inventory only and one considering water replenishment. At last, injection to both steam generators from the feedwater tank, at different times after SBO initiation was calculated. Afterwards, Secondary Side Feed and Bleed was studied.

This analysis has been completed by the study of the time frame available for Steam Generator inventory recovery by turning on a feedwater pump with a dedicated diesel generator.Ī High Pressure Station Blackout was analyzed first, as a base case. In particular, Secondary Side Feed & Bleed has been studied.

One of the main uses of full plant models is Severe Accident Management Guidelines support calculations.

The RPV lower plenum is occupied by a massive steel structure called “filling body” that was designed to minimize heavy water inventory.Ī summary of the nodalization development is presented here: the reactor vessel model includes all the experience gained during RELAP5/SCDAPSIM Mod 3.6 code extension to represent the specific design of Atucha reactors, whereas for the primary and secondary systems and the balance of plant, advantage was taken from a previous RELAP5 full plant nodalization. Heavy water coolant flows inside the channels, which are immersed inside the moderator tank. Each assembly is located inside an individual Zircaloy coolant channel. Atucha 2 is a PHWR, cooled and moderated by heavy water. For the Severe Accident Analysis of Atucha 2 Nuclear Power Plant in Argentina, a full plant nodalization for RELAP5/SCDAPSIM Mod 3.6 was developed.
