Great news. A zero emissions electricity grid requires nuclear, and will continue to do so for the foreseeable future; new battery techs are not there yet, and other non-intermittent sources like geothermal are too small scale and/or geographically specific. An irrational aversion to nuclear power has been a big obstacle to decarbonization, so every step in this direction is to be celebrated!
We don't need new tech, and while we do need nuclear in the long run, it is more important now that we switch off fossil fuels as quickly as possible. Nuclear is not fossil fuels, but it is notorious for taking a long time to build and get verified and turned on, as well as being horrendously late and over-budget. Renewables can be thrown up in a matter of months, are relatively very cheap and turn a profit quickly.
An irrational aversion to nuclear power is an obstacle, but there are plenty of rational objections and many of them point to nuclear being an obstacle/delaying tactic intended to sustain the fossil fuel industry for longer.
