RBMK Retirements

Post by Kirk Sorensen » Dec 29, 2018 2:15 pm

The Soviet Union built 26 of its RBMK (Reaktor Bolshoy Moshchnosti Kanalnyy, “High Power Channel-type Reactor”). These were graphite-moderated, light-water-cooled reactors intended to simultaneously produce power and plutonium. The most infamous of these reactors was the Chernobyl Unit 4 which exploded on April 27, 1986.

Russia retires Leningrad unit 1
Unit 1 of the Leningrad nuclear power plant has been withdrawn from service after 45 years of safe operation, Russian state nuclear corporation Rosatom has announced. It said the lead unit in the RBMK-1000 series was shut down at 11:30pm on 21 December. The reactor was gradually shut down in accordance with the technological regulations before being disconnected from the national grid. The unit was commissioned on 21 December 1973 and had since generated 264.9 TWh of electricity. In all its years of operation it has not experienced a single serious incident, Rosatom said.
Nine of these RBMKs remain operational. Kursk units 1 through 4, Leningrad units 2-4, and Smolensk units 1-3.

264.9 TWh of electricity at $0.05 per KWh is over $13 billion. The economic activity that is generated by nuclear power plants is amazing. Imagine if it was a priority to produce electricity at the lowest cost to the environment and to the consumer.

Graphite moderated NPP s are on the way out. I worry about new graphite design lifter.
