An inspector from Japan's Nuclear Regulation Authority (NRA) faced criticism for allegedly making threats without presenting technical evidence during a recent inspection of the Sendai Nuclear Power Plant operated by Kyushu Electric in Kagoshima Prefecture. This incident reportedly occurred last autumn when the inspector disagreed with Kyushu Electric representatives over the method of measuring the insulation of cables. The inspector not only failed to provide a scientific basis for their claims but also made comments that were perceived as intimidating, such as insisting on their standpoint regardless of the explanations presented.

As a result of the encounter, in February of this year, Kyushu Electric communicated with the NRA to express concerns about the significant burden on their team due to the inspector's demands. They requested that discussions remain constructive and based on technical evidence, even when disagreements arise. It was clear that the dynamics between regulatory inspections and the operational protocols of nuclear power facilities require a balance of authority and collaboration to ensure safety without inciting undue pressure on personnel.

The NRA has since instructed its inspectors to adhere to guidelines that encourage calm and evidence-based discussions during inspections. This case highlights the critical importance of maintaining professional integrity within regulatory bodies, ensuring that interactions with power operators do not devolve into intimidation, which can adversely affect operational safety and morale within the industry.
