This report describes the summary of 'A validation Test Planning of Piping Bellows Expansion Joint in Experimental FBR "JOYO" '. The planning followed 'A Feasibility Study of Piping Bellows Expansion Joint' which had been completed at oarai Engineering Center of PNC. The planning of validation test is one activity of the First Sub-Committee of the PROFIT Committee. Under the First Sub-Committee, a working group was organized for constructing the varidation test program. The working group had considered meanings/objectives, methods, schedules, expected results and expenses of validation test using experimental FBR 'JOYO'. The output of the working group presented in this repot was reported to and deliberated in the First Sub-Committee, the PROFIT Committee and a Technical Stearing Comittee in Oarai Engineering Center. The last choice was made by the Technical Stearing Comittee to push forward with the plan.

A test CW electron linac is designed to develop a high power accelerator to treat waste radioactive material. The linac is to be operated at the room temperature and is energized by two 1.2MW CW L-band klystrons to produce an electron beam with the energy of 10MeV and current of 100mA. The average beam power is 200KW-1MW for the duty factor 20%-100%. In designing such high power electron linear accelerator, an accelerating section having a traveling wave resonant ring is adopted. By adopting such type of acceleration section, it became possible to choose very short length of the accelerator sections to elevate the threshold current of beam break-up (BBU) keeping the high accelerator efficiency. In designing the linac with the traveling wave resonant ring, some special considerations and calculations are introduced. The variational method is used to calculate the sizes and parameters of the disk-loaded accelerator structure. There is the discrepancy of the order of a few hundredth of one percent between the calculated frequency and the experimental one. A kind of internal cooling water structure is adopted to disperse the generated heat by RF efficiently. Currently, its components development is in progress at OEC.
