Calvert Cliffs Unit 2 shut down automatically Monday night because of a leak of hydraulic fluid in the system that opens and closes turbine steam valves on the non-nuclear side of the plant.
All systems responded as designed. Technicians at the Lusby, MD-based facility will repair and fully test the system before returning the unit to service. Unit 1 remains at full power.
The Unit 2 shut down will not impact electrical service to Exelon customers.
Calvert Cliffs is on the western shore of the Chesapeake Bay in Calvert County and is Maryland’s only nuclear energy facility. The station is home to two pressurized water reactors capable of generating 1,756 megawatts combined.
Units 1 and 2 began commercial operation in 1975 and 1977, respectively.
A gas leak forced businesses on the north side of Iowa City to evacuate Thursday night after a construction crew struck a gas line.
Iowa City Fire Department crews arrived on the scene around 6 p.m. Thursday after the line break, which was in the alley next to Hamburg Inn No. 2. Fire trucks, a police squad car and an ambulance blocked the roadways of about a block of Market Street and the connected block of North Linn Street.
Restaurants and businesses on the east side of the block of North Linn Street evacuated around 6:30 p.m.
MidAmerican Energy crews headed to the scene to fix the line break, fire department Battalion Chief Eric Nurnberg said. He didn’t know how long it would take to repair the line.
Nurnberg said firefighters would remain on the scene until the line is repaired then check for any lingering gas before allowing anyone to re-enter the buildings.
Over $400,000 in damage occurred at a Heartland REMC substation in Wabash, IN, on November 25 after someone shot the transformer, officials said.
The substation is near the Red Bridge Marina on Mississinewa Reservoir Property. The substation lost power that night after someone shot the substation transformer, according to Indiana Conservation officers.
REMC personnel discovered the bullet hole in the substation transformer that had penetrated the radiator. Other bullet damage was apparent on the outside of the transformer, but did not penetrate it. REMC personnel did find spent rifle cartridges nearby which officers will examine as possible evidence.
Damages to the substation are at least $400,000 or more.
REMC Chief Executive Rob Pearson said evidence indicates the perpetrator stood at the locked gate entrance and fired at least two rounds, since all of the holes in the transformer were made by the same gun.
From the location of the shots as well as the number of shots, the shooting is believed to be an intentional act to damage Heartland REMC property, Pearson said.
“We believe it was intentional because there was more than one bullet on the transformer and we found more than one shell casing,” he said. “We knew it wasn’t a random stray bullet.”
Pearson said the damage also caused a hazardous oil leak around the substation, which had to be cleaned up.
This is the second time someone has shot and damaged the substation. Pearson said the equipment suffered similar damage from a bullet earlier this year.
Toshiba Surveillance & IP Video Products is introducing two new Pan-Tilt-Zoom (PTZ) 3MP IP dome cameras, both featuring 20x optical zoom and delivering streaming video at 2048×1536 resolution for applications requiring highly detailed surveillance, indoors and outdoors in any lighting environment.
Toshiba’s IKS-WP8203R PTZ camera can operate in the harsh outdoors with its IP66 enclosure protection, integrated heater and auto defogging, while the new IKS-WP8103 PTZ provides an attractive indoor solution for covering large spaces such as shopping malls, casinos or schools.
True Day/Night imaging with Digital Wide Dynamic Range empower both cameras to capture images in high contrast and changing light conditions down to 0.01 lux. In addition to 24V, both cameras end up powered with PoE+ which eliminates the need for power cables and reduces installation cost. Also, both are backed by ONVIF Profile S to ensure seamless interoperability with third-party ONVIF-conforming equipment and software.
A core benefit of the new PTZ cameras is powerful, built-in optical zoom capability. It enables up to 20x optical magnification (f=4.7 ~ 94 mm, F1.6 to F3.5) and achieves quick subject tracking through a high-speed auto focusing system so operators can react instantly to suspicious situations. The cameras’ ability to precisely identify small details, such as car licenses or facial features, means they are suitable for users that demand enhanced detail when zooming in, plus makes them able to handle installations where detailed coverage of longer distances is essential including airports, borders, roads, cities and campuses.
The cameras’ also have a high-speed 360° continuous pan that achieves surveillance of large areas without blind spots, and its precision -10° to 190° tilt drive offering almost instant preset positioning. Equipped with 256 presets, pattern tour, autoscan and auto flip, nothing escapes the cameras’ PTZ.

There were no injuries as a result of a blaze that erupted when a gas pipeline ruptured north of Kansas City, Missouri Tuesday night, officials said.
The fire ended up reported about 6:30 p.m. Tuesday in Platte County, north of Kansas City and not far from Kansas City International Airport, a Platte County Sheriff’s Department dispatcher said.
The responding Southern Platte Fire District said the blaze resulted from a pipeline explosion, though the cause was unclear.
The identity of the owner or operator of the pipeline was not immediately available.
The pipeline carries ethane and propane, Kansas City Fire Department officials said.
Joe McBride, a spokesman for the airport, said the blaze was not affecting flights at the airport and was not on airport property.
Three people suffered injuries after an aerosol plant explosion in Neodesha, KS, last Tuesday.
The blast forced an evacuation for residents in Neodesha, officials said.
Three people suffered injuries, including one worker who ended up transported to a Wichita hospital in critical condition, firefighters said. Neodesha is about 15 minutes north of Independence. The explosion happened around 6 a.m.
Additional tankers from neighboring areas were requested to help.
Several agencies responded including Neodesha Fire and law enforcement, Highway Patrol and Fredonia Fire and law enforcement, officials said.
In addition to the fire and evacuation, Neodesha firefighters said should not use city water due to extremely low pressure and possible contamination. Water should only end up used to flush toilets and other limited life-sustaining uses. Residents should not drink the water or use for cleaning.
According to a release, the city of Independence declared a Stage 3 water emergency. It says the city water treatment plant will stop taking in water from the Verdigirs River at 4 a.m. Wednesday and water testing will take place. This would likely cause many businesses in the area to shut down.
The cause of the explosion remains under investigation. Firefighters says the fire is under control but still burning. Crews are expected to work through the night.
A natural-gas explosion Wednesday night in downtown Canton, IL, killed an Ameron Illinois worker, officials said.
The killed worker was part of a crew that was investigating a gas leak in a building at 45 East Side Square. At least 11 others required hospital attention.
Fulton County Coroner Steve Hines identified the killed worker as 38-year-old Arturo Silva Jr., of Mapleton. Three other workers suffered injuiries, and two of them remained hospitalized Thursday, said Ameren Senior Vice President Ron Pate.
The explosion took place shortly before 6 p.m. The Ameren workers arrived about 5:30 following a report a contractor damaged a gas-service line, said utility spokesman Tucker Kennedy.
“The utility business is a close brotherhood, and our family is hurting right now,” Kennedy said about 10 p.m. during a news conference at the hospital.
“We express our deep sadness and our profound sympathies to the family of our fallen Ameren Illinois worker and ask everyone to keep their family and our family in their thoughts and prayers.”
