The accelerator served mainly for graft-polymerization for new material development, radiation effect study on semiconductors and various experiments of visiting users. The annual operation time of the electron accelerator is 706.3h. The Co-60 -ray irradiation facilities consist of three buildings (8 rooms) and cover a wide dose-rate range from 0.04 Gy/h to 20 kGy/h with eight irradiation cells. The annual operation time for the first, second cobalt irradiation facilities and food irradiation facility is 23,433h, 9,010h and 10,631h.

An electron accelerator and three -ray irradiation facilities were operated for various research subjects as operation plan in FY 2007 without serious trouble. The number of research subjects for the electron accelerator and -ray irradiation facilities is 505 and 1174, respectively. The number of experiment subject at the electron accelerator increased in the research fields of environment and nuclear facilities, and decreased in the field of heat resist. Also, the number at -ray irradiation facilities increased in the field of resource & bio-technology, and decreased in the field of nuclear facilities.

The No.1 accelerator has been smoothly on service since established in January 1986. The No.1 accelerator renewed both the high frequency inverter power supply in January 2000 and the accelerator control system in June 2001. The No.2 accelerator operation was terminated and the extended operation of the No.1 accelerator was started having one additional consignment operator at April 2005.

A detailed design for a New Material Nitric Acid Recovery Evaporator was carried out with a plan to use it to replace an already constructed stainless steel Nitric Acid Recovery Evaporator at the Power Reactor and Nuclear Fuel Development Corporation's Tokai Works. Most of the original Evaporator's conditions such as compliance with applicable laws, standards, structure, treatment performance and operating conditions were maintained when designing the new machine. The material is titanium with the addition of 5% tantalum. The Evaporator was designed with an operational life expectance of 10 years. We have calculated that the new Evaporator will have sufficient strength (including a seismatic design) and have the same evaporative performance as the already constructed one. During design, we referred to the results of already completed basic designs (Phase 1) of New Material Nitric Acid Recovery Evaporators, design and production of small-scale test equipment units, and the development of successful joints between different materials. We also considered manufacturing, installation, trial runs, maintenance, and the specifications for materials used for manufacturing, installation, piping and operation of the new Evaporator.
