In this study, we have investigated the spray system's capabilities to reduce fission products
in the containment atmosphere and control the containment pressure in a VVER-1000 …

Abstract Occurrence of the Severe Accidents (SAs) in Research Reactors (RRs) according to
the safety standards of the International Atomic Energy Agency (IAEA), despite the low …

It is necessary to evaluate the released gases distribution (especially hydrogen) to avoid
hydrogen accumulation and maintain containment integrity against the pressure loads due …

In this study, uncertainty and sensitivity analyses were performed with MELCOR 2.2. 18 to
study the hydrogen generation (figure-of-merit (FoM)) during the in-vessel phase of a severe …

An uncertainty analysis based on the Latin Hypercube Sampling (LHS) method and
MELCOR code for hydrogen production during a SA in WWER1000 nuclear reactor is …

To mitigate consequences of core melting, an ex-vessel core catcher is investigated in this
study. Instructions should be obeyed to cool down the corium caused by core melting. The …

The small-sized pressurized water reactor (PWR) characterized by its high inherent safety
and wide applicability, has become a promising type of reactor with broad prospects for …

The core catcher is used as a passive safety system in new generation nuclear power plants
to create a space in the containment for the placing and cooling of the molten corium under …

In order to explore the hydrogen source term characteristics under severe accidents of
marine pressurized water reactors (PWR) and effectively assess the hydrogen risk, the best …

Hydro-accumulators, as a passive part of the emergency core cooling system, have been
upgraded in different types of VVER-1000s. The number and performance of these systems …
