Safety, health and security are our top priorities and central to everything we do. We are passionate about the safety and well-being of our employees, our environment, our stakeholders and the public in general.

As part of a stringent planning and licensing process, we are required to carry out an extensive assessment of a range of potential natural events, including consideration of events with a probability of up to 1 in 10,000 years. This involves taking account of the possible effects of natural disasters such as tsunamis or storm surges, as well as the possible implications of climate change. These rigorous processes ensure that the nuclear power stations we rely on for electricity have an exemplary safety record.

Since 1967, Hitachi has been involved in the construction of more than 20 nuclear power stations. Throughout that time, the company has worked to enhance the reliability of the entire process, including significant research and development into the continuous improvement of its Advanced Boiling Water Reactors.

Hitachi’s Advanced Boiling Water Reactor (ABWR) technology is fully compliant with the international criteria for ensuring that there is a low probability of accidental damage to the reactor core. In response to the Fukushima Dai'ichi accident caused by the huge earthquake and subsequent tsunamis on 11 March 2011, a further layer of Defence in Depth (DiD) protection has been added to all existing power plant for enhanced safety.

Nuclear regulation
The UK nuclear industry has an outstanding safety record and is tightly monitored by the Office for Nuclear Regulation (ONR), which ensures that all nuclear plants are built and operated to exacting safety standards. Alongside the ONR, the Environment Agency, Natural Resources Wales and Scottish Environment Protection Agency ensure radioactive waste discharges and other potential environmental impacts are managed correctly.

Nuclear security
The  Office for Nuclear Regulation (ONR-CNS) also acts as the security regulator for the UK's civil nuclear industry through its Civil Nuclear Security Programme. It enforces the comprehensive legal and regulatory framework that is in place to ensure the security of nuclear installations and nuclear materials in transport.
