France stopped the reactor from the Flamanville nuclear power plant
Due to a technical failure, one of the two reactors at the Flamanville nuclear power plant was arrested, probably for several weeks. The communication service of the central states that there is no leakage of radiation. The largest producer and supplier of electricity in France, EDF said the second reactor of the plant was "broke down in the night of Monday to Tuesday." A backup transformer then took over, but it was impossible to repair the main reactor quickly. For this reason, the authorities decided to stop at 18:15 (local time). "It is highly likely that the transformer must be changed," said the communication service, adding that it could take weeks.
For now, no exact date of restarting of the second reactor were announced.
EDF states, in the communiqué issued last night that this failure has "no impact on plant safety, or the environment" because the first reactor of the Flamanville plant operates in the usual diet and "contributes to supply the national grid. "
The reactors of the Flamanville nuclear power plant produced 300 MWe each what 1 which represents 4.5% of the French nuclear output and 80% of the electricity consumption of Normandy.

December 18, 2015 accident at Russia's Leningradskoe power station
英語字幕
The conditions inside the power plant nuclear block and outside nuclear power station are normal
There is no reason to evacuate the nuclear power station personnel or neaby residents
Ecologists from Green Peace stated that the escaped steam was radioactive
However,the background radiation is normal
Head of Sosnovy Bor city administration Mr. Sodovsky said nuclear power station personnel not actively engaged with the shut down of the reactor had been released to go home
Eyewitnesses of the accident and the inhabitants of the Russia's northern capital are scared. The second unit was stopped at the station.

MOSCOW (QHA) -
The accident occurred at the second power unit when a pipe with steam cracked in turbine hall yesterday. The steam filled the room, and leaked beyond the power plant. The employees of the Leningrad Nuclear Power Plant (LNPP) had to go home. The second unit was stopped manually, Ekho Moskvy reports.
According to specialists, the release was radioactive, because the waste steam entered the so-called loop reactor coolant. However, the population was encouraged not to panic.
East wind carried a cloud in the direction of Estonia and Finland.
The LNPP is located 80 kilometers from St. Petersburg, on the Gulf of Finland. It is considered one of the largest producers of electricity in the north-west Russia.
Emergency stop of the second power unit of Leningrad NPP took place on Friday, 18
December 13 hours and 50 minutes. The reason for stopping and cooling down the reactor was a sudden intake of radioactive steam from a faulty pipe in one of the rooms of the turbine shop.
Both the turbine to operate the reactor were stopped. During cooldown steam produced in the reactor is discharged through the pipe into the environment. South southeast wind around 5 meters per second (not typical for this area) refers radioactive steam toward the Gulf of Finland, in the direction of Vyborg - Zelenogorsk. The radiation background in the middle of pine trees, 5 km from the emergency unit at 17 hours was based on the results of measurement "Green World" was 20 mR / hr.
Thus, the five millionth city of St. Petersburg, located 40 km east of SELA were lucky this time. According to some sources was increasing background radiation only a few times in the station area.

Reference: The second power unit of Leningrad NPP operates 40 years, with 30 years of project resources. Life extension has been made without the legally required public hearings and state environmental expertise.
To date, all 4 LNPP operate in a prolonged life. The oldest of the Chernobyl reactor series in Sosnovy Bor plans to stop only in 2018 after 45 years of operation.
The eastern part of the Gulf of Finland enters into a ten-year streak of increased risks of accidents at nuclear facilities. In the period up to 2026 on the one hand will produce an extended service life and have a higher probability of accidents of RBMK-1000 reactors of Leningrad NPP. In the same period, planned for commissioning new power units of Leningrad NPP-2 (VVER-1200), will also have an increased risk of accidents due to errors of designers, builders, and even inexperienced personnel.
So ahead of "resonance" increase the probability of accidents in the Sosnovy Bor nuclear cluster.
