Decommissioning Decontamination Dose Rate Reduction Fuel Retrieval Shielding
Removal of large rubble from the roof and walls of the reactor building collapsed due to the hydrogen explosion and dose rate reduction for human workers to begin preparation work shall be accomplished for retrieval of spent fuel from the spent fuel pool at Fukushima Daiichi Nuclear Power Station Unit3.
This paper describes the method of survey and evaluation, decontamination and shielding method for dose rate reduction on operational floor of Fukushima Daiichi Nuclear Power Station Unit3....

Contaminated water management Decontamination Fukushima Daiichi Nuclear Power Station (NPS)
Tokyo Electric Power Company Holdings, Inc.(TEPCO) is undertaking decommissioning of Fukushima Daiichi Nuclear Power Station (NPS) steadily and safely, incorporating domestic and international expertise, to fulfill our responsibility for the March 2011 Fukushima Daiichi nuclear accident.
To address contaminated water issues, TEPCO takes preventive and multi-layered measures based on a three-pronged strategy: "Remove Source of Contamination," "Isolate Fresh Water from Contaminated Areas," and "Prevent Leakag...

Pipe wall thickness in power plant have been measured during the periodic inspection to evaluate soundness and safety by Ultrasonic Testing (UT). But it takes a long time and man power to complete measurement and evaluation. In this study, “Flex Dry UTM” is developed as a new kind of UT system for making it possible to monitor pipe wall thickness continuously. It is attached directly to pipe under the lagging material without using coupling medium. The maximum temperature it can be applied is developed to b...

Condition-Based Maintenance Dry coupling IoT Nondestructive inspection On-line monitoring Pipe wall thinning Reduction of radiation exposure Remote monitoring Ultrasonic testing probe Wall thickness measurement
In power plant, most of the pipe is examined for confirming the thickness of the pipe wall during the period of inspection in the suspension of the plant. As pipe thinning phenomenon can progress mostly in the running of the plant, the measuring for the thickness value in running time is needed for confirmation of health and safety evaluation precisely. In this study, “Flex Dry UTM” was developed as a new type of UT system for making it possible to monitor pipe wall thickness continuously. Its measuring per...

Charpy impact test Electron beam welding Low alloy steel Reactor pressure vessel Reconstitution method of test specimen Surveillance test
Additional RPV surveillance test are required to extend the operation license of nuclear power plants. Since the number of surveillance test specimens is limited, it is important to establish a reconstitution technique of the surveillance test specimen. Applicability evaluation of reconstituted impact test specimen by electron beam welding for RPV surveillance test were conducted, and it was confirmed that reconstituted impact test specimen was applicable to RPV surveillance test.
