Bahrain signs a nuclear collaboration MOU with the U.S.
Less than a week after news broke of the U.S. entering into civil nuclear talks with Malaysia, the U.S. State Department announced that Secretary of State Marco Rubio and Bahrain’s Minister of Foreign Affairs Abdullatif bin Rashid Al Zayani have also signed a memorandum of understanding concerning civil nuclear cooperation.

A shattered pellet injector based on in situ technology was installed on the HL-2A tokamak, and preliminary experiments were performed recently. In this paper, a fast current shutdown experiment introduces shattered pellet injection (SPI). In comparison with spontaneous disruptions and massive gas injection, SPI has advantages for disruption mitigation. The experimental results show the hard-X-ray radiation intensity (40 to 60 keV) rapidly falling from 20 to 0 when SPI is used. From this, we can infer that runaway electrons are suppressed. This observation indicates that SPI should be a good candidate for current fast shutdown in the future.
