Development of critical heat flux correlation for In-vessel retention
Journal of Nuclear Science and Technology, 2020In-vessel retention (IVR) is a strategy for severe accident management in which the lower head of the reactor vessel is submerged in a water-flooded reactor cavity.

In-Vessel Retention of Molten Core Debris for CAP1400
18th International Conference on Nuclear Engineering: Volume 3, 2010 In-vessel retention (IVR) of core melt through external reactor vessel cooling (ERVC) is a key severe accident management strategy to ensure that the vessel head remains intact and eliminate consequent major threats to containment integrity. To maintain the margin against the failure of the reactor vessel and make sure of the feasibility of IVR for its

Conjugate heat transfer analysis for in-vessel retention with external reactor vessel cooling
Annals of Nuclear Energy, 2016Abstract A conjugate heat transfer analysis method for the thermal integrity of a reactor vessel under external reactor vessel cooling conditions is developed to resolve light metal layer focusing effect issue for in-vessel retention. The method calculates steady-state three-dimensional temperature distribution of a reactor vessel using coupled ...

IN-VESSEL CORE RETENTION STRATEGY (IVCRS)
, 1999 The objective of the IVCRS CA is to address the possibility to ensure corium retention inside the vessel of future reactors in case of core melting. With this aim in view, the present Project has been launched in order to: 1 - establish the technical requirements and the safety approach for future NPPs; 2 - Propose several solutions aiming at ...

In Vessel Retention Analisys with Astec code [PDF]
, 2012 A Severe Accident countermeasure can be the retention of the melted core inside the reactor vessel. A way to achieve this kind of corium retention is by removing heat from the steel vessel by flooding the reactor cavity. A first calculation was performed in order to assess In-Vessel Core Damage Retention (IVR) possibilities for an AP1000 reactor as a ...

Simulant Melt Experiments on In-Vessel Retention Through External Reactor Vessel Cooling
Nuclear Technology, 2006 External reactor vessel cooling (ERVC) is one of the major severe accident management strategies for operating nuclear power plants. Flow circulation inside the reactor pressure vessel (RPV) insulator should be effective enough to ensure sufficient heat removal via ERVC.

In- and ex-vessel coupled analysis for in-vessel retention
Progress in Nuclear Energy, 2018Abstract In-vessel retention (IVR) in the manner of external reactor vessel cooling (ERVC) is an important severe accident mitigation strategy, which has been applied to some advanced light water reactors, e.g. AP1000. This main assessment method on the effectiveness of IVR is the lumped parameter (LP) model, which has been applied to assess the ...

ASTEC application to in-vessel corium retention
Nuclear Engineering and Design, 2009Abstract This paper summarizes the work done in the SARNET European Network of Excellence on Severe Accidents (6th Framework Programme of the European Commission) on the capability of the ASTEC code to simulate in-vessel corium retention (IVR). This code, jointly developed by the French Institut de Radioprotection et de Surete Nucleaire (IRSN) and ...
