Advancement in FBR Fuel Recycle Development in Japan

Nomura, Shigeo; Yamato, Aiji; Ojima, Hisao

CD-ROM, 5P., 5 Pages, 2003/00

In Japan, the Feasibility study for commercialization of FBR and its fuel cycle system (FS) has been conducted under the collaboration of JNC and the electric utilities since 1999. Through the FS, candidate technology will be selected by 2015.

Radioactive waste management research programs inevitably include laboratory solubili and sorption studies to provide data for radionuclide transport model. Estimation of lubility strongly depends on the reliability of thermodynamic data (e.g., carbonato-colexes) and may also depend on kinetic data on alteration of solubility limiting solid ases. Existing sorption data may include some kind of retardation mechanisms to be excded (e.g., precipitation). To develop these fundamental data, we must also consider a rge number of radioactive elements, a large number of factors (e.g., pH, Eh, complexinligands) in the repository environmentg, and numerous solid and aqueous species of radnuclides along with the many absorbents. Therefore, a systematic approach and researchlan are needed for obtaining and evaluation thermodynamic and sorption constants. The cus of this session was on thermodynamic data for aqueous species and solid phases imptant to the geological disposal system, on kinetic data

Nuclear energy is the second largest source of electric power in the United States. Tdate, nuclear power plants produced over twenty percent of the nation's electricity. Aof August 1991, there were 112 nuclear power reactors in the United States, and two mo were being built. By the year 2000, approximately 40,000 metric tons of nuclear wasteill be in temporary storage at reactor sites throughout the coutry. That amount is twi the amount that currently exists. In order to handle such waste, as well as the addedolume to be produced after the year 2000, the U. S. Department of Energt (DOE) is in t process of developing the waste management system that was authorized by the U. S Coness in 1987. The authorized system is illustrated in Figure 1. To summarize, spent nucar fuel from commercial power reactors will be accepted by the DOE at the reactor siteand transported to a monitored retrievable storage (MRS) facility for temporary storagand preparation for permanent disposal in a gelogic rep

Su㎜ary report on the environmental monitoring around Tokai area following the accident at Chernobyl Nuclear Power Plant

An accident took place at the Chernobyl nuclear power plant in USSR in the early hours of 26 April 1986. The plant caught fire and some degree of reactor inventry was released to the environment. Following the accident, debris of the radioactivity from Chernobyl was detected in all the European countries and countermeasures were taken in some countries. In Japan, many kinds of radionuclides were detected in rain, airbone dust and other environmental samples from 3 May and "Headquaters for Radioactivity Countermeasure" was organized in the Japanese Government. Health and Safety Division at the Tokai Works, PNC, performed the environmental monitoring for the Chernobyl accident in addition to the statutory monitoring program. This report presents results of the environmental monitoring performed at Tokai Works. Furthermore, study on the environmental transfer parameters and preliminary estimation of the committed dose equivalent to the public around Tokai area are discussed.
