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.

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.
