Since 2015, Mitsubishi Nuclear Fuel (MNF) has joined in a Japanese R&D project of ATF founded by the Ministry of Economy, Trade and Industry (METI) as a subcontractor to Japan Atomic Energy Agency (JAEA) which is the prime contractor to METI. In this program, MNF plans to evaluate an influence of Silicon Carbide (SiC) composite cladding upon fuel rod behavior in current pressurized water reactors (PWR). This paper reports the evaluation result of the applicability of fuel rod with SiC composite cladding for a conventional PWR. For the applicability evaluations of SiC composite to conventional PWR, both of analytical evaluations and out-of-pile tests for SiC composite were conducted. Analytical evaluations were performed by Mitsubishi's own fuel rod design code and the fuel rod behavior evaluation code developed by JAEA. These codes were modified to evaluate the behavior of the fuel rod with SiC composite cladding. As out-of-pile tests, thermal diffusivity measurement and autoclave corrosion test for SiC composite samples were performed. Test apparatus were developed for evaluation of performance of SiC composite under the condition simulated design basis accident (DBA).

Mitsubishi Nuclear Fuel (MNF) plans to evaluate an influence of Silicon Carbide (SiC) composite cladding upon fuel rod behavior in current pressurized water reactors (PWR). In this presentation, the evaluation result of the applicability of fuel rod with SiC composite cladding for a conventional PWR will be reported.

Due to its hydrogen-generation rate and reaction heat being lower than those of conventional Zircaloy, SiC is expected to be an appropriate material for accident-tolerant fuels. There are, however, only a few knowledge on behavior of SiC composite cladding under design basis accident condition (DBA). In this study test apparatus were developed for evaluation of behavior of SiC composite cladding and the mock-up tests using SiC cladding were performed under the condition simulated DBA.

SiC composite material is one of the candidate material as the accident tolerant fuel. The acquisition of the irradiation properties, the evaluation of fuel design and accident safety are main problems for the SiC composite material. For the solution, out- and in-pile testings of SiC composite, development of evaluation technique of fuel behavior, core characteristic and the safety at accident, analyses and evaluations by using the developed techniques have been carried out.

The SiC/SiC composite has lower thermal conductivity than current Zry cladding, and it is necessary to raise a gap between the pellet and the cladding to prevent their contact from the viewpoint of pellet integrity. In the presentation, it will be reported that the effect of reduction of cladding diameter and hollow pellet on the temperature and the reactivity of the core.

The stress of SiC cladding to the existing PWR is important to evaluate the integrity of SiC cladding. It is necessary to comprehend mechanical properties of each of longitudinal and circumferential direction because there is anisotropy in mechanical properties of SiC cladding. The A-EDC test which was the circumferential direction mechanical test developed in recent years. The mechanical properties of SiC cladding in circumferential direction was measured using the A-EDC.

It is expected that SiC cladding tube has high corrosion resistance and high strength under LOCA condition in existing PWR. There is little data for SiC cladding tube in the high temperature environment. So the apparatus which was capable of testing at LOCA simulated condition was manufactured for SiC cladding tube. The modified LOCA test was carried out for investigating the behavior of SiC cladding tube.
