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.

At the L-2M stellarator, in the electron cyclotron resonance heating regime, the processes of plasma self-organization were studied in different successive phases of plasma confinement during the facility shot. It is shown that in the phase of initial plasma heating, because of the absence of plasma-wall interaction, the canonical pressure profiles of the electronic component are not formed. In the quasi-stationary phase, the forming pressure profiles are close to the canonical one, and the energy loss is somewhat higher than in the phase beginning immediately after switching off the microwave heating pulse. After turning off the microwave pulse, the self-organization processes form the canonical pressure profiles of the electronic component in plasma, which ensure minimal energy loss from the plasma. In this case, the total power of energy losses from the plasma is proportional to the cube of the plasma energy.
