Ontario’s advanced nuclear technology firm Terrestrial Energy yesterday announced the signing of a letter of intent (LOI) with TerraPraxis, a U.K.-based nonprofit devoted to climate solutions, to cooperate on the latter’s Repowering Coal initiative—a program aimed at integrating clean heat sources with existing infrastructure at coal-fired power plants in North America and elsewhere.

Feinstein

Although previously a supporter of Diablo Canyon’s early closure, California Sen. Dianne Feinstein took to the pages of the Sacramento Bee yesterday to endorse life extension for the state’s sole operating nuclear power plant.

Citing projected electricity shortfalls in California due to the effects of climate change, Feinstein writes that “Pacific Gas and Electric Company should reconsider its decision to close Diablo Canyon by 2025. The utility should get the plant relicensed instead, retiring it once the state can replace its production with clean sources.”

The senator continues: “I remain concerned about the lack of long-term storage for spent nuclear fuel and am working to develop better solutions. But at this point, keeping Diablo Canyon open and producing carbon-free energy is more important.”

French utility giant EDF has announced that its NUWARD small modular reactor design will be the case study for a European early joint regulatory review led by the French Nuclear Safety Authority (ASN). Also participating in the review process will be the Czech Republic’s State Office for Nuclear Safety (SUJB) and Finland’s Radiation and Nuclear Safety Authority (STUK).

China’s State Council recently approved the construction of four Westinghouse AP1000 reactors—two at China’s Sanmen plant in Zhejiang Province and two at the Haiyang plant in Shandong Province.

The plants currently house two AP1000 units each. Sanmen’s reactors are rated at 1,157 MWe and Haiyang’s at 1,170 MWe. Sanmen-1 and -2 began commercial operation in 2018. Haiyang-1 started commercial operation in 2018, and Haiyang-2 in 2019.

With three commercial teams under contract to produce reactor designs for nuclear thermal propulsion rockets that would use solid high-assay low-enriched uranium fuel to heat hydrogen propellant, NASA’s investment in nuclear thermal propulsion (NTP) has increased in recent years. But just as there is more than one way to fuel a terrestrial reactor, other fuels are under consideration for future NTP rocket engines.

Électricité de France recently announced the formation of an advisory board for NUWARD, France’s small modular reactor project. According to the company, the establishment of the International NUWARD Advisory Board (INAB) is a major step forward in support of the technology’s development.

The Nuclear Regulatory Commission has issued a final safety evaluation report for the first of several licensing topical reports (LTR) submitted by GE Hitachi Nuclear Energy (GEH) for the BWRX-300 small modular reactor, the company announced on December 1.

The initial LTR, titled “BWRX-300 Reactor Pressure Vessel Isolation and Overpressure Protection,” was submitted to the NRC in December 2019, officially beginning the U.S. licensing process. This LTR forms the basis for the “dramatic simplification” of the BWRX-300, according to GEH.

In its announcement, GEH noted that two additional LTRs were submitted in early 2020 and that it anticipates reviews of those reports to be completed in the coming months. A fourth LTR was submitted in September 2020, the company added.
