"AECL also reports that initial inspections of NRU following the seismic event experienced in the Ottawa Valley on the afternoon of June 23 confirm that the seismic instruments that protect the reactor were not activated and no injuries occurred. A detailed walk-down of the NRU facility is in progress to confirm no damage to equipment or structures."Also, there's a bit of a glitch mentioned in the update (airborne tritium part) but the statement says that it's not a problem in terms of regulatory levels. Otherwise, they say they're still on track for resumption of isotope production by the end of July.
Precarious, as always.
