The ministry said radiation levels were normal. TASS news agency, citing an official in the city of Severodvinsk, reported a short-term spike in radiation levels.
The explosion is the second military accident within a week.
On Monday, a fire at an ammunition depot in Siberia caused a massive explosion that killed at least one person and injuring 13 more, forcing several thousand people to flee their homes in the Krasnoyarsk region.
