Monju is a sodium-cooled, MOX-fueled loop type reactor with 3 primary coolant loops, producing 714 MWt / 280 MWe.
The successor to Monju is expected to be a larger demonstration plant that will be completed around 2025, built by the newly formed Mitsubishi FBR Systems company.
Fortunately, the leak occurred in the plant's secondary cooling system, so the sodium was not radioactive. However, there was massive public outrage in Japan when it was revealed that Power Reactor and Nuclear Fuel Development Corporation (PNC), the semigovernmental agency then in charge of Monju, had tried to cover up the extent of the accident and resulting damage. This coverup included falsifying reports and the editing of a videotape taken immediately after the accident, as well as the issuing of a gag order to employees regarding the existence of the real tapes.
On November 24, 2000, Japan's Atomic Energy Commission announced their intention to restart the Monju reactor. This decision was met with resistance by the public, resulting in a series of court battles. On Jan. 27, 2003, the Nagoya High Court's Kanazawa branch made a ruling reversing its earlier 1983 approval to build the reactor, but then on May 30, 2005, Japan's Supreme Court gave the green light to reopen the Monju reactor.
The restart is currently scheduled for October 2008, having been moved back five months.
