G7 pledges support for nuclear at Italy meeting
The Group of Seven (G7) recommitted its support for nuclear energy in the countries that opt to use it at a Ministerial Meeting on Climate in Italy last month.
In a statement following the April meeting, the group committed to support multilateral efforts to strengthen the resilience of nuclear supply chains, referencing the goal set by 25 countries during last year’s COP28 climate conference in Dubai to triple global nuclear generating capacity by 2050.

Large amounts of tritium will inevitably be produced during operation from the Thorium Molten Salt Reactor (TMSR) fueled by lithium salt, which is detrimental to the human body. Therefore, it is necessary to evaluate the radiation dose of the generated tritium. The tritium production, emission, and radiation dose of TMSRs were estimated by numerical calculation. According to this study, a 2-MW(thermal) TMSR produces 3.33E+14 Bq·yr−1 of tritium, discharges 2.42E+13 Bq·yr−1 of tritium, and causes 1.06 μSv·yr−1 of radiation dose. A 30-MW(thermal) TMSR produces 5.00E+15 Bq·yr−1 of tritiu.m, discharges 3.62E+14 Bq·yr−1 of tritium, and causes 2.02 μSv·yr−1 of radiation dose. A 2250-MW(thermal) TMSR produces 3.75E+17 Bq·yr−1 of tritium, discharges 2.77E+16 Bq·yr−1 of tritium, and causes 79 μSv·yr−1 of radiation dose. The radiation dose of TMSRs is much less than 1 mSv·yr−1, which is the dose limit for internal recruitment in China. It is determined that TMSRs are safe for humans regarding tritium hazard.
