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.

Carbon Sheet Pump(CSP) has been proposed to be installed on the vacuum vessel wall of the Large Helical Device(LHD) in order to reduce the hydrogen recycling and improve the energy confinement.
The CSP of C/C composite with temperature below 200 °C can pump high energy hydrogen particles such as charge exchange fast neutrals by trapping them. The saturated hydrogen particles can be removed simply by heating the carbon sheet above 800 °C. One of the requirement on the CSP design for LHD is that the temperature of the vacuum vessel must be maintained to be below 70 °C to avoid excessive heat flux to the LHD superconducting magnet system.
The first design of CSP for LHD is presented, and a successful demonstration of heating the CSP carried out.
