Geothermal Isn't Expensive: The Reservoir Always Has the Final Say Somewhere beneath a volcanic ridge, a drill bit is turning through rock that has not moved in two million years. It costs money every second it turns. And nobody on the surface — not the engineer, not the financier, not the minister who announced the megawatts — knows yet whether that well will produce steam or silence. That single moment explains almost everything people get wrong about geothermal energy. Geothermal is routinely described as expensive, slow, capital-hungry and haunted by drilling risk. Investors are reminded that tens of millions can disappear underground before a single megawatt reaches a grid. All of that is true. But it is not the whole truth. The uncomfortable question the industry keeps avoiding is this: is geothermal expensive, or is the way we develop geothermal making it expensive? Those are two completely different problems. One is geology. The other is us. Why Geothermal Refuses to Be...
South Korean organizations unite to innovate in the maritime industry with the development of Small Modular Reactor (SMR) powered ships
Nine South Korean organisations have signed a memorandum of understanding (MoU) to cooperate on the development and demonstration of ships and offshore systems powered with small modular reactors (SMRs). The partners will also develop marine systems and the production of hydrogen using molten salt reactors (MSRs).

Since July, an advisory panel - the Green Transformation (GX) Executive Committee - has been considering the implementation of major changes in energy, all industries, and the economy and society in order to achieve the goal of achieving net-zero emissions by 2050. The government's GX implementation meeting was held on 22 December, during which a roadmap for the next ten years was agreed as a "basic policy for the realisation of GX".
Under the new policy - which describes nuclear power as "a power source that contributes to energy security and has a high decarbonisation effect" - Japan will maximise the use of existing reactors by restarting as many of them as possible and prolonging the operating life of aging ones beyond the current 60-year limit. The government also said the country will develop advanced reactors to replace those that are decommissioned.
Under revised regulations which came into force in July 2013, Japanese reactors have a nominal operating period of 40 years. Extensions may be granted once only and are limited to a maximum of 20 years, contingent on exacting safety requirements.
On 21 December, Japan's Nuclear Regulation Authority approved a draft of a new rule that would allow the reactors to be operated for more than the current limit of 60 years. Under the amendment, the operators of reactors in use for 30 years or longer must formulate a long-term reactor management plan and gain approval from the regulator at least once every 10 years if they are to continue to operate.
The new policy will effectively extend the period reactors can remain in operation beyond 60 years by excluding the time they spent offline for inspections from the total service life.
Under the new policy, Japan will also develop and construct "next-generation innovative reactors" to replace about 20 reactors that are set to be decommissioned.
Bills to implement the new policy will be submitted to parliament during the ongoing session.
Nuclear policies vary by country, but some common policies include:
Nuclear energy development: This policy outlines the goals and objectives for the development of nuclear energy within a country, including the construction and operation of nuclear power plants.
Nuclear safety and security: This policy sets guidelines and regulations to ensure the safe and secure operation of nuclear power plants, and to minimize the risk of accidents and security threats.
Nuclear waste management: This policy addresses the disposal of nuclear waste, including the storage, transportation, and disposal of radioactive material.
Decommissioning of nuclear facilities: This policy outlines the procedures for decommissioning nuclear facilities, including the safe shutdown of reactors and the disposal of radioactive waste.
International cooperation: This policy governs international cooperation and information exchange between countries on nuclear energy and related issues, including safety, security, and the peaceful use of nuclear energy.
Nuclear non-proliferation: This policy seeks to prevent the spread of nuclear weapons and to promote disarmament, through measures such as international treaties and inspections.
Nuclear energy research and development: This policy provides funding and support for research and development in nuclear energy, including the development of new reactor designs and fuel cycle technologies.
Nuclear energy regulation: This policy outlines the roles and responsibilities of regulatory agencies, and sets standards and requirements for the construction, operation, and decommissioning of nuclear power plants.
