admin CRIIRAD, the independent radiological French monitoring laboratory already had monitors in place and so far is not seeing unusual levels of radioactive aerosols as a result of the explosion. Beyond Nuclear is monitoring their updates (in French) here.
No further updates on the aftermath of the explosion at the Marcoule facility have come in. The explosion took place in one of the ovens of the incinerator that melts low-level radioactive detritus mostly emanating from the country's 58 reactors. Nevertheless, the concerns - and the potential for a devastating outcome as a result of an accident at the multi-facility nuclear site, serve as a reminder of the risks that continue to be taken by prolonging the use of nuclear energy as an electricity source.
