The ITER vacuum vessel (VV) R&D has progressed with the international collaborative efforts by the Japan, Russia and US Parties during the Engineering Design Activities (EDA). Fabrication and testing of a full-scale VV sector model and a port extension have yielded critical information on the fabrication and assembly technologies of the vacuum vessel, magnitude of welding distortions, dimensional accuracy and achievable tolerances during sector fabrication and field assembly. In particular, the dimensional tolerances of 
3 mm for VV sector fabrication and 10 mm for VV sector field assembly have been achieved and satisfied the requirements of 5 mm and 20 mm, respectively. Also, the basic feasibility of the remote welding robot has been demonstrated. This report presents detailed fabrication and assembly technologies such as welding technology applicable to the thick wall without large distortion, field joint welding technology between sectors and remote welding technology through the VV R&D project.

This report describes the result of study of manufacture and test of the Alcohol Waste Processing test Equipment. The experimental fast Reactor, JOYO, stores the radioactive alcohol waste at storage tank. As this alcohol waste can not be processed with existing equipment, about 5 m
of alcohol waste is stored. And the amount of this waste increases every year. So it is necessary to process this alcohol waste by appropriate method, for example, chemical resolution. In this fiscal year, based on the study results in the last fiscal year on catalytic oxidation method, the test equipment is manufactured and conclusive test is performed. And the investigation and tests on applicability of the other sodium removal technologies is also performed. The study results obtained in this fiscal year are as follows. [(1)Conclusive Test of the alcohol waste processing] (a)As a result of 1/2 scale test, target processing performance of 1.25
/h can be obtained for simulative alcohol waste of 80% alcohol, but processing performance for simulative alcohol waste of 20% could not satisfy the target value. (b)In case that high temperature pipes, which are under condition of 350 deg C in actual plant, are arranged, it is difficult to arrange equipment in alcohol waste tank room (A-106). [(2)Investigative and Test about Sodium removal] (a)The sodium in alcohol waste can be separated and removed from carbonate compound. (b)A sodium (carbonate compound and metals) in alcohol waste could be removed by wired-film evaporator, and it is considered to be possible that this equipment is applied to actual plant. (c)ICP (Inductively Coupled Plasma) is considered to be effective method as one of alcohol resolution processes. [(3)Basic Design of alcohol waste process equipment] In this basic design, as far evaporation-dry process, the components, process ability, properties of waste, chemical mass balance, safety for fire and explosion, and the plot plan are investigated. As a result, ...
