OSLO, June 23 (Reuters) - Sweden's OKG, a part of E.ON group, said on Tuesday it would decide in the third-quarter whether to permanently shut down two nuclear reactors at its Oskarshamn plant in Sweden.
"E.ON has informed of its intention as majority owner of OKG AB to pursue a direction to permanently discontinue electricity production at OKG unit 2 as soon as possible," OKG said in a market message.
The 638-megawatt reactor has been offline since May 2013 and may never restart if OKG board
It wasn't a tsunami but it had the same effect: A huge cluster of jellyfish forced one of the world's largest nuclear reactors to shut down – a phenomenon that marine biologists say could become more common.
Operators of the Oskarshamn nuclear plant in southeastern Sweden had to scramble reactor number three on Sunday after tons of jellyfish clogged the pipes that bring in cool water to the plant's turbines.
The Swedish Radiation Safety Authority (Strålsäkerhetsmyndigheten) has asked nuclear waste contractors at the Oskarshamn nuclear plant to review their security requirements after cracks were found in the pools where nuclear waste is temporarily stored on site.
Cement walls are cracked in two of ten waste pools at the Clab storage facility, which is run by the Swedish Nuclear Fuel and Waste Management Company (Svensk Kärnbränslehantering, SKB).
STOCKHOLM--The Oskarshamn 2 nuclear reactor in southern Sweden will be taken offline Thursday after the Swedish Radiation Safety Authority ordered an immediate shut-down due to safety concerns.
The authority said the reactor's operator, OKG, which is owned by German utility E.ON AG and Finnish Fortum Oyj, hasn't been able to show that important safety functions comply with the required standards.
The authority's concerns relate mainly to diesel generators which are part of the plant's backup power system.
The nuclear reactor at Oskarshamn was closed down late on Saturday night after a fire broke out at the plant.
Although the fire, which broke out in the turbine hall of Unit 2, was quickly put out by the plant’s own emergency services, the reactor and the turbine were closed down as a precautionary measure.
It is still unclear when the reactor 2 can be restarted again, with investigations ongoing.
Finland and Sweden are working on technology for the safe burial of nuclear waste in bedrock. A partly Finnish-designed machine was on display at the Oskarshamn nuclear power plant in Sweden. The purpose of the device is to transport the dangerous materials deep into caverns excavated for the purpose.
The highly radioactive spent nuclear fuel needs to be isolated for at least 100,000 years.
Sweden is preparing to bury a total of about 12,000 tonnes of radioactive uranium waste.
STOCKHOLM, Nov 4 (Reuters) - Swedish power group Vattenfall said on Tuesday an inspection had revealed one broken control rod and cracks in about 30 percent of others at its Forsmark 3 reactor.
Forsmark communications director Claes-Inge Andersson told Reuters that about 100 out of 169 rods had been inspected and cracks had been found in some 25-30 percent of them.
STOCKHOLM, Sweden (AP) — Managers of an atomic power plant in Sweden used janitors to guard the facility when the alarm system was malfunctioning, according to a critical report Thursday from the country's nuclear watchdog.
In a statement on its Web site, the Swedish Radiation Safety Authority called the incident at the Oskarshamn plant serious because the workers had no training as security guards.
Stockholm - Two of Sweden's 10 nuclear reactors were to be offline for at least a month as checks continued on the control rods used to control the nuclear fission process, officials said Monday. The Swedish Radiation Safety Authority last week ordered operators to check the control rods after cracks were detected in the control rods at one of the three reactors at the Oskarhamn nuclear plant, south-eastern Sweden.
STOCKHOLM, Sweden - A Swedish nuclear reactor was shut down Tuesday for safety checks after an annual review of a similar reactor found cracks in several control rods.
Workers found cracks in at least five of 90 rods of a reactor at the Oskarshamn nuclear plant during annual maintenance work earlier this month. That reactor was closed for maintenance and has yet to reopen.
