The experimental fast reactor JOYO served as the MK-II irradiation bed core for testing fuel and material for FBR development for 16 years from 1982 to 1997. During the MK-II core operation, extensive data were accumulated from the plant characteristic tests. Tests conducted at JOYO included operating characteristic tests for confirming operational safety, performance tests for confirming design performance of the MK-II core, and special tests for research and development ofthe plant. In this report, the outline and the results of each test item are shown. These test data can be provided by the magnet-optical disk.

The experimental fast reactor "JOYO" served as the MK-II irradiation bed core for testing fuel and material for FBR development for 15 years from 1982 to 1997. During the MK-II operation, impurities concentrations in the sodium and the argon gas were determined by 67 samples of primary sodium, 81 samples of secondary sodium, 75 samples of primary argon gas, 89 samples of secondary argon gas (the overflow tank) and 89 samples of secondary argon gas (the dump tank). The sodium and the argon gas purity control data were accumulated from in thirty-one duty operations, thirteen special test operations and eight annual inspections. These purity control results and related plant data were compiled into database, which were recorded on CD-ROM for user convenience. Purity control data include concentration of oxygen, carbon, hydrogen, nitrogen, chlorine, iron, nickel and chromium in sodium, concentration of oxygen, hydrogen, nitrogen, carbon monoxide, carbon dioxide, methane and helium in argon gas with the reactor condition.

This report describes the operational experience during the MK-II core and a theme of the future Fuel Cleaning Facility in "JOYO". Following results are obtained. (1)The sodium guantity adhered the spent core elements is influenced by the inner structure of the elements. (2)The corrosion product guantity in the washing waste water is mainly influenced by the corrosion product adhering to material surface. (3)The sodium guantity in the water which is contained in a can differs from the kind of elements. (Maximum value of sodium is about 8 grams) (4)During the washing by demineralized water, reaction velocity and guantity of sodium which adheres to a element differ from the kind of elements. Therefore, it is necessary to establish the washing way depend on the elements.
