Prototype Fast Breeder Reactor “Monju” Start of Unloading Operation of the Fuel Assembly from the Core
FAPIG No. 196 pp.8 to 15 (2019)
The prototype fast breeder reactor “Monju” has already started (from June 2017) the unloading operation period (about 5.5 years: until the end of 2022) of the fuel assembly, which is the first stage of decommission. Among them, the first “Processing of fuel assembly” operation (86 in total) was conducted from August 2018 to January 2019 as the first handling of the fuel assembly.
Fuji Electric provided technical support, such as dispatching technicians throughout the period, in cooperation with Japan Atomic Energy Agency for the "Processing of fuel assembly" operation, and contributed to the completion of the operation while experiencing various troubles.
This manuscript introduces the contents of the first "Processing of fuel assembly" operation and the overview of the trouble status.

KEYWORDS:fast reactor, Monju, unloading, decommission

Hokuriku Electric Power Company Shika Nuclear Power Station Access Control Equipment
FAPIG No. 196 pp.16 to 22 (2019)
Summary:Given the need for stricter radiation exposure control for workers working at nuclear power plants, Fuji Electric Co., Ltd. has manufactured and delivered the access control equipment for Shika Nuclear Power Station under the guidance and cooperation of Hokuriku Electric Power Company. In this paper, therefore, we introduce the particular equipment equipped with the following functions:
-Preventing from entering the radiation control area when wearing other person’s glass badge or not wearing any dosimeters or glass badges; and
-Reducing the burden on workers

KEYWORDS:Access Control Equipment stricter radiation exposure control

Method of Radioactivation Calculation Necessary for Decommissioning of Nuclear Facilities
FAPIG No. 196 pp.23 to 30 (2019)
It is anticipated that the decommissioning of the commercial nuclear power plants and the high energy accelerator facilities will increase in future. To abolish and release the radiation control area of nuclear facilities with radioactivity, the evaluation is necessary to the amount of activated radioactivity in the apparatus, equipment and structure in the control area. We explain the method of radioactivity calculation to obtain the concentration distribution of activated radioactivity in the nuclear facility. We explain the contents and present situations of the neutron transport calculation method, the activation cross section, and the decay data. Then, the outline of the currently available radioactivity calculation codes is described.

KEYWORDS:decommissioning, nuclear facility, radioactivity, radioactivity calculation, activated radioactivity, neutron transport calculation, decay data, activation cross section, radioactivity calculation code

Melting/Incineration Furnace and Peripheral Equipments in OWTF
FAPIG No. 196 pp.31 to 36 (2019)
Japan Atomic Energy Agency (JAEA) Oarai Research & Development Institute is storing their radioactive waste in the area of the institute. The capacity of the storage is limited, therefore they have constructed Oarai Waste Reduction Treatment Facility (OWTF), which was finished in March 2019.
OWTF processes the mixed solid waste of burnable objects (paper, clothe), non-flammable object (vinyl chloride), and metal.
This paper introduces the melting/incineration furnace, the main parts of OWTF, designed and manufactured by Kawasaki Heavy Industries.

KEYWORDS:volume reduction, waste process, melting, incineration, remote controlled, induction coil
