The Japan Atomic Energy Research Institute is now constructing the High Temperature Engineering Test Reactor(HTTR), which employs a visual inspection of core support graphite structure, as an inservice inspection (ISI), In this inspection, TV camera wil1 be used to investigate the alignment and integrity of the structure. Therefore, the ISI system, a combination of radiation tolerant TV camera and graphic processing system, is developed and examined its detectability and viewing ang1es using a simulated hot plenum of HTTR, which has artificial defects.
As a result of a series of tests, it was confirmed that this system satisfied the requirements and was quite applicable for the ISI system of HTTR core support graphite structure. In addition, further improvement of the system, like a remote contro1 procedure, wil1 be investigated.
