The Bilibino Nuclear Power Plant (Russian: Билибинская АЭС [pronunciationⓘ]) is a power plant in Bilibino, Chukotka Autonomous Okrug, Russia. The plant is equipped with four EGP-6 reactors.[2] The plant is the smallest and the second northernmost operating nuclear power plant in the world.[3] Plans to begin a shutdown procedure of the plant in 2019 have been announced,[4] and it will be replaced by the floating nuclear power station Akademik Lomonosov.[5]
Radiation exposure
As of 2012, the EGP-6 reactors at the plant exposed personnel and staff on average to 3.7 mSv/year.[6] This makes up 18.5% of the 20 mSv/year designated radiation workers can receive. The exposure by the Bilibino Nuclear Power Plant is higher than the average for Russian nuclear power plants which sits at 1.26 mSv/year.[6]
Improvements since the Fukushima-Daiichi accident
Following the 2011 Fukushima nuclear disaster, measures were taken to ensure safety and emergency responses for Russian nuclear power plants. These plants included RBMK, BN, WWER-440, WWER-1000, and EGP reactors.[6] For nuclear power plants with EGP's, mobile pumping sets, motor-driven pumps, 0.2 MW mobile diesel generator units (MDGU), and 2 MW diesel generator plants (MDGP) had been supplied for mobile emergency response.[6] Seismic protection systems (SSP) were introduced.[6] The "Management Guide for Beyond Design Basis Accidents at RMBK NPPs Including Severe Accidents", a guide for prevention and mitigation for an accidents concerning graphite-moderated reactors, was revised with the incidents of Fukushima in mind.[6]
