core cooling FuNushima Daiichi Nuclear Plant Unit 1 Isolation Condenser TRAC code
In this study, we aimed to quantitatively evaluate cooling capacity of isolation condenser (IC) for core cooling in FuNushima Daiichi Nuclear Plant Unit 1. In order to evaluate cooling capacity, decay heat em ted from fuels in reactor core was calculated. We used the data of nuclear fuel and rated thermal power which is released by TEPCO. We analyzed IC with TRAC code. We made an experiment in order to checN IC’s input data. Because analysis data is close to experimental data, we made sure validity of inpu...

FBR LDIE SG Two phase flow Wastage phenomena
Wastage phenomena occur when a heat transfer tube is failed in a Steam Generator (SG) of Fast Breeder Reactor (FBR) and its mechanism is still unexplained. We focused on Liquid Droplet Impingement Erosion (LDIE) as a factor of the wastage phenomena and performed a basic study with a partial mock-up water test simulating a piping group in SG for quantitative evaluation of LDIE. First, we did visualization tests of high pressure and high speed jet into water. The test section consists of a failure heat ...

AgX Lawsuit Preventive maintenance Public acceptance Severe accident Silver Zeolite
A gas-liquid mixing nozzle and a multi-layer metal fiber filter are used, and a silver zeolite filter is installed for the purpose of removing organic iodine. Based on this technology, we have developed a demonstration machine for a large-capacity air purification system that purifies a large amount of contaminated air. A gas- liquid mixing nozzle driven by air blown from a blower sucks and accelerates water to form a high-speed two-phase flow. With this acceleration and centrifugal force field of water, al...

Adsorbent AgR AgX Annulus FCVS Preventive maintenance Radioactive iodine Severe accident SGTS Silver zeolite
When a severe accident (SA) occurs at a nuclear power plant, a large amount of hydrogen will be generated in the containment vessel. As a measure, a static catalytic hydrogen recombination device (PAR) can be used to remove the hydrogen. In the case of significant damage to reactor core, the metal reaction between water and zirconium in the core will generate oxygen. The PAR device can promote the recombination reaction of hydrogen and oxygen using platinum or palladium as a catalyst to convert into water s...

Adsorbent AgR AgX Annulus FCVS Preventive maintenance Radioactive iodine Severe accident SGTS Silver zeolite XeA
Since it is difficult to remove radioactive noble gas, the development of high performance adsorbent has been desired from the viewpoint of exposure prevention. We were able to develop a new adsorbent, XeA that has more than 10 times the performance of existing products. By utilizing this adsorbent in nuclear facilities, it is possible to contribute to the miniaturization of equipment, non-combustibility and reduction of radiation exposure....
