A reactor at the Calvert Cliffs nuclear power plant has resumed operations after a planned refueling outage, owner Constellation Energy Nuclear Group announced Tuesday. In February, one reactor shut down after an electrical malfunction caused by melting snow on a leaky roof, triggering the other to shut down as well, a Constellation spokesman said at the time. One reactor returned to service March 1 after confirming there were no safety issues, but the second reactor was scheduled to be shut down for refueling.

I read with interest the commentary, "The nuclear option" (Aug. 26), in The Baltimore Sun, and I wanted to comment on just one aspect of this public pitch for nuclear power. The author omitted the fact that Constellation Energy made application to the U.S. Nuclear Regulatory Commission to construct and operate Calvert Cliffs 3 in 2009, as I recall. They went into partnership with the French-owned Electricite de France to form UniStar Nuclear Energy to build an evolutionary pressurized water reactor similar to what is notoriously still under construction in Finland.

UniStar Nuclear Energy has asked the federal Nuclear Regulatory Commission to review the rejection of the French-controlled company's bid to build a third reactor at Calvert Cliffs nuclear power plant. UniStar filed a petition Monday asking for a hearing before the five member commission on the Atomic Safety and Licensing Board's ruling that the company is ineligible for a reactor operating license because federal law bars foreign ownership of a nuclear plant. The licensing board on Aug. 30 gave the company 60 days to find a U.S. partner or its application would be shelved.

The Calvert Cliffs nuclear power plant restarted its reactor that automatically shut down last week after a malfunction at the Southern Maryland facility. Operator Exelon Corp. said Monday that the Unit 1 reactor returned to full power at 9 a.m. Sunday. The facility's second reactor continued to run during the outage, one of three incidents in the last eight months in which one or both of the units had unplanned shutdowns. The malfunction that caused Unit 1 to power down Thursday morning happened during electrical breaker testing, Exelon said.

Joseph Cunniffe sees the proposed third nuclear reactor at Calvert Cliffs as a huge opportunity for his Sykesville-based firm GSE Systems, which develops simulation and training systems for the power-generation industry. So did more than 100 companies that gathered Thursday in Baltimore for an event drawing suppliers and vendors looking to do business with Areva, the world's largest reactor maker, which is designing and building the proposed third unit with construction company Bechtel.

Federal regulators plan a hearing Jan. 26 on a challenge to a French company's bid to build a third reactor at the Calvert Cliffs nuclear power plant, and will take public comments the day before. The Atomic Safety and Licensing Board will air contentions by four anti-nuclear groups that the Nuclear Regulatory Commission staff has not adequately weighed alternatives to building the facility. The hearing begins at 9:30 a.m. in the Albright Building, 205 Main St. in Prince Frederick.

A malfunction at the Calvert Cliffs nuclear power plant caused an automatic shutdown of one of the two reactors there Thursday morning, the latest in a series of issues at the Southern Maryland facility. Chicago-based Exelon Corp., which operates Calvert Cliffs, said the malfunction happened during electrical breaker testing. The Unit 1 reactor shut down as a result at about 10:15 a.m. "All safety systems responded as designed and the plant came off-line as expected," Exelon said in a statement.

A federal environmental review has found no reason not to permit construction of a third Calvert Cliffs nuclear power reactor in southern Maryland, the Nuclear Regulatory Commission announced Friday. The final environmental impact statement by the NRC and the U.S. Army Corps of Engineers Baltimore District recommends issuance of a construction and operating permit to Unistar to build a 1,500 megawatt pressurized water reactor near Lusby in Calvert County. Other regulatory hurdles remain.

One reactor at Constellation Energy's Calvert Cliffs Nuclear Power Plant automatically shut down Wednesday afternoon after a temporary problem distributing electricity to the grid, a company spokesman said. Calvert Cliffs I remains shut down as officials troubleshoot and investigate why that problem occurred at 1:51 p.m., said the spokesman, Dave Fitz. "Plant staff took appropriate action," he said. "The safety of Calvert Cliffs was never threatened from this activity." Staff reported the shutdown to the NRC within two hours, Fitz said.

The Calvert Cliffs Nuclear Power Plant shut down one of its reactors Tuesday after employees at the southern Maryland facility detected problems with a control rod. Operators took the plant's Unit 1 reactor offline around 8:30 a.m. to replace one of the electrical coils connected to a control rod and test all the other control rods, said Kory Raftery, a spokesman for Calvert Cliffs. The move came after monitoring of the reactor picked up "electrical noise" in that control rod, a sign that part of the connection might have gone bad, he said.

Federal inspectors found no violations as they delved into the reactor shutdowns in January at Calvert Cliffs in Southern Maryland, the Nuclear Regulatory Commission said Friday. An electrical malfunction caused both of the nuclear power plant's reactors to shut down during a snow and ice storm in January, sending natural gas prices soaring as energy providers rushed to make up for the lost electricity production. The commission sent a three-person special inspection team to the plant the following week.

The Nuclear Regulatory Commission announced Monday that it is conducting a special inspection at the Calvert Cliffs nuclear power plant in Southern Maryland after an electrical malfunction caused the two reactors there to shut down. The plant, which restarted both reactors over the weekend, suffered the shutdown after snow and ice during a storm Jan. 21 apparently affected a ventilation louver filter and caused a short circuit. After the electrical supply system shut down, so did several plant systems and components that rely on electricity, the nuclear regulatory agency said Monday.

The operators of Calvert Cliffs nuclear power plant in southern Maryland shut down one of its two reactors Thursday after a control rod assembly malfunctioned during testing, federal safety regulators announced. The shutdown occurred without complications and did not pose any risks for the public or plant staff, Nuclear Regulatory Commission spokesman Neil Sheehan said. Unit 2 was powered down around 5 p.m. Thursday after operators checking a control rod "received some indication that electrical maintenance was needed on one of the assemblies," said Kory Raftery, plant spokesman.

A new report suggests that a substantial number of U.S. nuclear reactors — including one or both at Calvert Cliffs in Southern Maryland — are at risk of early retirement. Mark Cooper with the Vermont Law School's Institute for Energy and the Environment said a third of the country's nuclear fleet have a number of risk factors, largely economic, that could lead to their owners' deciding to shut them down before their licenses expire. A single problem, such as a costly repair, could be enough to push any of the reactors over the brink, he said.

The Nuclear Regulatory Commission said Thursday that it has ordered a venting upgrade for nearly a third of the reactors in the country, including ones at the Peach Bottom Atomic Power Station just north of Harford County. Peach Bottom, in Delta, Pa., has two of the 31 reactors that must now have venting systems that can better handle accidents. The commission's order is part of its review effort following the 2011 nuclear meltdown in Fukushima, Japan, after an earthquake and tsunami.

One of two reactors at the Calvert Cliffs nuclear power plant in southern Maryland was shut down again Tuesday, the second unplanned outage in the past two weeks. Plant operators powered down Unit 2 manually around 5:30 a.m. after a pump that feeds water to a steam generator shut down because of high vibrations, according to Neil Sheehan, spokesman for the Nuclear Regulatory Commission. The cause of the pump's vibrations appears to be a failed mechanical coupling between the pump's motor and the pump, he said.
