We use Advanced predictive maintenance technologies to maintain reactor pressure vessels (RPVs) and reactor internals, the most critical equipment in nuclear power plants, to ensure the safety of nuclear power plants.
We use water jet peening (WJP), one of its own superior technologies, to maintain reactor internals.
WJP is a technology that reduces residual stress on welds by spraying the area with a high-pressure water jet (The Japan Society of Maintenology registered it as a heritage maintenance technology in 2020.)
We have developed a very small underwater robot able to move around freely under water to inspect or maintain small compartments within RPVs and reactors. These robots are currently being used in power plants.
We use its advantageous ISI equipment (UT equipment) to maintain the body and pipes of RPVs.
Hitachi, Ltd. opened a comprehensive training/validation facility in the Omika Works to improve nuclear power generation facilities’ response to cyberattacks. We will provide a cyber defense training service.
This service is a solution using nuclear power plants simulators for organizational response training for cyberattacks targeting nuclear power plants and will continually support the enhancement of their customers’ cyber security.
