Structural Integrity Research for Reactor Pressure Vessel Under In-Vessel Retention of a Core Melt
Volume 1: Operations and Maintenance, Aging Management and Plant Upgrades; Nuclear Fuel, Fuel Cycle, Reactor Physics and Transport Theory; Plant Systems, Structures, Components and Materials; I&C, Digital Controls, and Influence of Human Factors, 2016In-Vessel Retention (IVR) is one of the most important severe accident mitigation strategies of the third generation passive Nuclear Power Plants (NPP). It is intended to demonstrate that in the case of a core melt, the structural integrity of the Reactor Pressure Vessel (RPV) is assured such that there is no leakage of radioactive debris from the RPV.

Characterization of in-vessel hydrogen isotope retention of JT-60U
Journal of Nuclear Materials, 2011Abstract Retention and depth profile of all hydrogen isotopes (hydrogen, deuterium and tritium) in the carbon tiles of outer divertor, outboard baffle plate and outboard first wall in JT-60U, which were mostly eroded, were measured by TDS, SIMS and TIPT, and discussed from view points of tile temperature, incident energy and flux of impinging H, D ...

Study of Potential for In-Vessel Retention Through External Reactor Vessel Flooding: Code Comparison
2017External Reactor Vessel Cooling (ERVC) is an important severe accident management means. In order to cool the melted corium which has relocated in the lower head, the ERVC strategy consists in flooding the reactor cavity to immerge the reactor vessel.

Scandinavian Journal of Haematology, 1978
A total of 17 patients with hypertension undergoing renal vein or adrenal vein catheterization were investigated in order to ascertain the number of megakaryocytes in blood from the inferior vena cava, the femoral artery and a cubital vein. On an average 11.9, 3.8, and 4.5 megakaryocytes per ml were found, respectively.

Natural convection for in-vessel retention at prototypic Rayleigh numbers
Nuclear Engineering and Design, 2000Abstract The ACOPO experiment simulates natural convection heat transfer from volumetrically heated pools at a half-scale reactor lower head geometry (hemispherical). New data for internal Rayleigh numbers of up to 1016 are presented, correlated and discussed, in relation to other available correlations. These ACOPO results confirm a key component of
