The company added that its teams were "carrying out the necessary diagnostics and interventions" to get both reactors fully back online.

It is produced by nuclear fission for use in medical gauges and devices, but can also be a byproduct of nuclear reactors and weapons testing, the agency said.

It can be expensive to buy and maintain – the process is so intense it requires a complex reactor and regular cleaning.

Some Oregon progressives give a nod to the bureaucracy that once mired nuclear reactors and say it’s time to give windmills and solar panels a faster pass.
