It's kinda sad that nowadays that you see News like this and move on, as anything said about Russia is more likely than not fake, but this seems fairly well verified.
Russia has belatedly admitted that the mystery explosion which released radiation into the air last Thursday, triggering warning alerts across towns near the northern port cities of Arkhangelsk and Severodvinsk, involved a “small-scale nuclear reactor”.
Radiation levels had spiked to 20 times their normal levels after the incident at a military testing ground in Russia’s Arkhangelsk region, prompting an emergency response team to deploy in full nuclear radiation protective gear, as photos which came out in the aftermath appeared to show. Consistent with early speculation, western defense officials and analysts now believe it was a failed test of a Russian nuclear powered cruise missile.

“A bright memory of our comrades will forever live in our hearts,” the statement said.
The statement, though, shed little light on exactly what detonated on Thursday at the White Sea testing range. No use for the propulsion unit was mentioned, although President Vladimir V. Putin previously boasted that Russia has developed a nuclear engine for long-range missiles. And there was no explanation why the authorities in a nearby city had reported rising radiation levels for a brief period several hours later.
While the government has provided no full explanation of what happened, Rosatom’s statement suggested a mishap during a test of a new class of nuclear-engined weapons that Mr. Putin first spoke publicly about last year.

The rocket engine that exploded seems to be one powered basically by a small but very hot nuclear reactor. Here is the model:
