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.

Recent favorable results on START have caused renewed interest in low aspect ratio tokamaks. To design an economical next-step spherical tokamak to study confinement scaling and high beta plasmas, we have developed a transport scaling and device optimization code. This code OPT, benchmarked against START, includes 10 empirical confinement scaling laws and essential tokamak physics such as stability limits. Parameters are optimized separately for each scaling law and physics goal. Using OPT we find for R/a=1.2 to 2.0 one can achieve βN=5 and <β>=30% with just two neutral beams (PNB<3.5 MW) for Ip≥0.75 MA, and Ro≥0.6 m. In contrast, if one insists on using the nominal device parameters, Ip=1 MA and Ro=0.8 m, with each scaling law, achieving βN=5 requires typically PNB⋍7.5 MW.
