When the Department of Energy announced Innovation Network for Fusion Energy (INFUSE) awards earlier this month, Savannah River National Laboratory was named a recipient of two of the 18 awards. SRNL released a statement on July 19 explaining how a national lab with a long history of supporting environmental management and national security missions can lend a hand in the development of future commercial fusion power.

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. March 2021 marked 10 years since the earthquake and tsunami devastated Japan and crippled the Fukushima nuclear station. This article from our March issue remains timely since various news outlets continue to report on the dangers of the Fukushima waste water without providing context to the Japanese plan to discharge the water. The March issue of Nuclear News also included a great review article from Lake Barrett outlining the current status of the decontamination and decommissioning going on at Fukushima.
The Tokyo Electric Power Company (TEPCO) became a household name a decade ago as the operator of the Fukushima Daiichi nuclear power plant, center of the largest nuclear accident in a generation. Now in 2021, as a result of the continuous mitigation efforts, TEPCO is currently storing 1.2 million cubic meters of treated wastewater—and counting—in more than 1,000 large storage tanks on site. This wastewater has been in the spotlight for the past few years since current projections show that storage capacity will run out by 2022.

Laurentis Energy Partners, a subsidiary of Ontario Power Generation (OPG), has launched a new program to produce helium-3. The He-3 will be obtained from tritium stored at OPG’s Darlington nuclear power plant, a four-unit CANDU station located about 100 kilometers east of Toronto.
Darlington houses one of the world’s largest reserves of tritium, which is a by-product of the heavy water used in CANDU reactors.

Using basic hand tools and remote manipulators, operators at Savannah River Nuclear Solutions (SRNS) were able to reduce radiation exposure to workers performing cutter head maintenance in the Savannah River Site’s Tritium Extraction Facility (TEF).
According to SRNS, the innovative procedure proved to be an excellent example of real-world application of As Low As Reasonably Achievable (ALARA) principles of time, distance, and shielding.

The Japanese government will soon announce the decision to dispose of stockpiled Fukushima wastewater into the Pacific Ocean, according to an AP News story published last Friday. The decision is years in the making and follows the guidelines from a panel of government-appointed experts named the Subcommittee on Handling of the ALPS-Treated Water (ALPS Subcommittee).
