Japan Struggles to Find a Site for Its High-Level Radioactive Waste

The Nuclear Waste Management Organization of Japan recently backed the further survey of two potential disposal sites for high-level radioactive waste in Hokkaidō. The government has struggled to convince municipalities to participate in review procedures, with a growing list of stakeholders calling for a new approach to the selection process.

A Three-Step Process

The Japanese government and nuclear power plant operators have long grappled with how to dispose of spent fuel and other high-level radioactive waste. Authorities finally settled on the approach of burying waste deep underground at facilities 300 or more meters below the surface. In 2002, NUMO, the Nuclear Waste Management Organization of Japan, began hunting for a storage location by inviting municipalities to put themselves forward as candidate sites. To date, this “volunteer” policy has netted only three participants, the towns of Suttsu and Kamoenai in Hokkaidō and Genkai in Saga.

The Indian Point nuclear power plant was an energy juggernaut for 50 years, generating a quarter of the electricity that powered New York City’s iconic, glowing skyline.

It is well into its decommissioning process after shutting down in 2021: The remaining waste of the radioactive fuel that once generated all of that power has been sealed inside more than 120 hulking metal and concrete canisters.

The Nuclear Revival: How Nuclear Reactors Have Evolved

~ Đào Thu Hằng ~ Bình luận về bài viết này

#CNAInsider We chart the evolution of nuclear power, from the first controlled chain reaction to today’s small, micro modular reactors and the pursuit of fusion. New designs are being tailored to meet the energy needs of remote communities, AI infrastructure, and climate-conscious cities.

The episode highlights how nuclear power is being adapted to local contexts, featuring China’s pebble-bed reactor, Finland’s underground district heating plant, and Indonesia’s floating nuclear concept. It also examines Westinghouse’s portable microreactor and the fusion research underway at ITER in France and KSTAR in South Korea. Engineers, scientists, and policy experts weigh in on how nuclear energy is being reimagined to deliver clean, reliable power in a rapidly changing world.

Estimates show small modular nuclear reactors would provide most expensive power and will not be available until 2030

Electricity generated by solar and on-shore wind is the cheapest in Australia, even after the significant expense of integrating them into the power grid is factored in, according to new analysis from the CSIRO.

Nuclear fusion breakthrough a milestone for the future of clean energy, US officials say

Ella Nilsen

Source: CNN — 

US Department of Energy officials announced a history-making accomplishment in nuclear fusion Tuesday: For the first time, US scientists produced more energy from fusion than the laser energy they used to power the experiment.

A so-called “net energy gain” is a major milestone in a decadeslong attempt to source clean, limitless energy from nuclear fusion – the reaction that happens when two or more atoms are fused together.

The experiment put in 2.05 megajoules of energy to the target and resulted in 3.15 megajoules of fusion energy output – generating more than 50% more energy than was put in. It’s the first time an experiment resulted in a meaningful gain of energy.

NUSCALE

NuScale Power is on track to build the first small modular nuclear reactor in America faster than expected.

Two weeks ago, NuScale’s small modular nuclear reactor design completed the Phase 1 review of its design certification application (DCA) by the U.S. Nuclear Regulatory Commission. That’s a huge deal because Phase 1 is the most intensive phase of the review, taking more hours and effort than the remaining five phases combined.

The map above shows which countries have operating commercial nuclear power stations and which ones do not as of April, 2016. At last count, 31 countries generate at least some of their electricity needs via nuclear power.

Here are 13 interesting facts about these countries and nuclear power. Tiếp tục đọc “Nuclear Vs Non-Nuclear Powered Countries: 2016 Facts” →
