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.

One of the most important considerations in the design of electronic systems for post-accident monitoring in a nuclear power plant is how to deal with the complex and uncertain radiation environments. Without using special design methodologies and adequate protection, nonradiation-hardened commercial-off-the-shelf (COTS) electronic components can easily be damaged. In this paper, a new design methodology is proposed so that COTS components can be used in building post-accident monitoring systems (PAMSs). To validate the effectiveness of the methodology, a prototype wireless post-accident monitoring system has been designed, implemented, and evaluated in a 60Co gamma radiation environment. It has been concluded that even at a dose rate of 20 krad (Si)/h, the prototype system operates satisfactorily even after being irradiated for 21 h. The system also operates satisfactorily at a low dose rate of 200 rad (Si)/h. It can be concluded that, even with COTS components, the proposed design can effectively extend the lifespan of post-accident monitoring systems in different radiation environments. Based on the experimental results, it can be said with confidence that the developed radiation-tolerant wireless monitoring system can operate for at least 8 h under the highest observed dose rate (530 Sv/h) encountered during the Fukushima Daiichi nuclear disaster and would have been able to provide crucial information to first responders following the accident.
