Vent Clearing during a Simulated Loss-of-Coolant Accident in a Mark I Boiling Water Reactor Pressure-Suppression System

The effect of fuel thermal conductivity on the behavior of LWR cores during loss-of-coolant accidents

The effect of variation in thermal conductivity of light water reactor fuel elements on core response during loss-of-coolant accident scenarios is examined. Initially, a simplified numerical analysis is utilized to determine the time scales associated with dissipation of stored energy from the fuel into the coolant once the fission reaction is stopped. The analysis is then followed by full reac...

Evaluation of Single Failure Effects During Loss of Coolant Accidents For A VVER-440 Reactor

This paper describes the results of an analysis of loss of coolant accidents (LOCA's) for the Soviet designed, light water cooled and moderated reactors referred to as VVERs. The VVER unit selected for this analysis is designated as VvER-440 Model 213. This plant generates 440 Mwe and is of current interest since meen are now operating and additional units are in various stages of construction ...

Accident scenarios of the TRIGA Mark II reactor in Vienna

The safety report of the TRIGAMark II reactor in Vienna includes three accident scenarios and their deterministic dose consequences to the environment. The destruction of the cladding of the most activated fuel element, the destruction of all fuel elements and a plane crash were considered scenarios in that report. The calculations were made in 1978 with the software program named STRISK. In th...

Nuclear Fuel Behaviour in Loss-of-coolant Accident (LOCA) Conditions

Dose Distribution of 131 I , 132 I , 133 I , 134 I , and 135 I Due to a Hypothetical Accident of TRIGA Mark - II Research Reactor

An attempt has been made in the work to assess radiological dose due to the deposition of 131 I, 132 I, 133 I, 134 I, and 135 I on ground, vegetation, milk and meat considering a hypothetical accident of TRIGA Mark-II research reactor at AERE, Savar, Bangladesh. Contribution of dose from ingestion of vegetation due to 131 I has been found to be dominant (62.96%). Also found that contribution of...
