Dangerous nuclear operation in Kola Peninsula

Saturday, October 25, 2008

Experts from the Russian state nuclear energy company Rosatom are preparing for the removal of spent nuclear fuel from a submarine reactor in the base of Gremikha on the Barents Sea coast. The operation is highly complicated and dangerous, they say.

The spent nuclear fuel will be removed from a reactor formerly belonging to a “Alfa”-class submarine. The operation is part of the Russian effort to decommission and scrap the many retired nuclear subs left after the Soviet period.

Kola-I's operating license was extended

Thursday, August 14, 2008

KOLA-I'S OPERATING LICENSE WAS EXTENDED until July 6, 2018, by the Russian regulator, Rostekhnadzor. In June 2003, the regulator authorized a limited extension of five years while it undertook a full safety assessment following upgrades and modernization work undertaken since 1990. The assessment was carried out in line with Russia's current nuclear legislation and also took into account the recommendations of the International Atomic Energy Agency and other international experience in assessing the safety of nuclear power plants.

DEPRESSURIZATION OF CONTROL ROD HOUSING DISCOVERED DURING ROUTINE INSPECTION

The unit was operating at rated power. Routine inspection of the control rod drive mechanism housings was in progress. Boron traces and small steaming were discovered in the flange joint of control rod housing 12-43 (located in central position) with nozzle of the reactor vessel head. The reactor was normally unloaded and then cooled down according to the operating procedure. After disassembling of the control rod housing erosion wear of base metal in the flange (on mating surface) was identified. Previous inspection on 27.02.94 did not detect any indications of the defect.

COOLANT LEAK FROM THE AUXILIARY PRIMARY CIRCUIT CLEANUP SYSTEM DURING COOLDOWN OF THE PRIMARY CIRCUIT


The unit was in maintenance. At 19:35 while performing the reactor cooldown effort coolant leak from a NB50 pipeline of the primary water makeup system into the sealed rooms occurred. At 21:03 the leak was stopped by isolating the affected pipeline. The leak from the pipeline was isolated under the normal design configuration in the Unit confinement. Radiation situation in the Unit attended rooms, on-site and off-site remained unchanged. Activity releases through the vent stack above limits prescribed for normal operation did not occur.

UNIT SCRAM DUE TO INADVERTENT ACTUATION OF PRESSURIZER PILOT RELIEF VALVE

The unit was operating at 330 MWe power. Due to inadvertent opening of one out of two pressurizer pilot relief valves (PRV) primary circuit pressure drop occurred. On primary pressure drop to 115 kgf/cm2 AZ-1 protection actuated and the reactor was scrammed. All safety systems functioned as designed. While safety system operation during the 1 hr 10 mins. period several PRV actuations occurrred; primary pressure varied in the range of 128-72 kgf/cm2; as a result of pressurizer PRV and AZ-1 protection actuation the temperature droppped from 283 C to 254 C during 7 mins.
