Following the Fukushima Daiichi nuclear reactor crisis in Japan, the U.S. nuclear industry is more closely scrutinizing existing facilities, and long-standing problems are placing some plants under the microscope .

Two U.S. steel fabricators and a German pipe manufacturer have announced the formation of a joint venture to produce components for the 130-turbine Cape Wind farm in development off Nantucket Sound and other offshore wind farms emerging along the East Coast. EEW Group Monopile foundations at at EEW's Rostock, Germany facility, similar to the facility that will be built in Massachusetts to serve nascent offshore wind industry off the U.S. Atlantic coast.

Ten capped landfills will be reused as solar fields under an agreement between Cape & Vineyard Electric Cooperative, located in Cape Cod and Martha's Vineyard, and American Capital Energy, North Chelmsford, Mass. The 18.3-MW project on Cape Cod and Martha's Vineyard, the largest of its type in New England, is expected to produce 22,500 MWh per year, enough energy to power 3,132 Cape and Vineyard homes, according to the cooperative. Energy produced from the project will provide about 1.1% of electric power for cooperative customers. A construction date for the $83-million project has not yet been scheduled. The federal government
Preliminary analysis of a ceiling light fixture that fell into moving traffic in early February at Boston's Big Dig tunnel system suggests the fixture shows signs of severe corrosion caused by salt from snow and ice treatment.

Even though corrosion causes substantial damage to U.S. infrastructure every year, “corrosion is not well understood,” says Ted Greene, professor of mechanical engineering at the Wentworth Institute of Technology, Boston.

New Hampshire landowners are fighting the Northern Pass project, a $1.1-billion transmission line designed to import a reliable source of renewable hydropower from Canada into New England, where transmission and generation are constrained. Developers of the 180-mile line recently agreed to remove five alternatives for the line and focus on routes that would use existing rights-of-way south of Groveton, N.H., as well as a preferred route and several alternatives to the north that would require new rights-of-way. In an April 12 filing with the U.S. Dept. of Energy, Northern Pass officials successfully obtained an extension until June 14 to identify
Two months after a 110-lb light fixture fell onto a roadway along Boston’s Big Dig highway project, Massachusetts Dept. of Transportation inspectors have found some corrosion in the 23,000 lighting fixtures that line the Central Artery tunnel. In the wake of the resignation of a highway administrator following a delay in notifying the public about the fixture, the agency’s operational procedures are under scrutiny. “I have acknowledged our failure to alert the public in a timely manner and the lapse in our internal communications, which we are currently working to address,” state transportation Secretary Jeffrey Mullan says. “We are continuing
The state of Massachusetts is seeking damages from the manufacturer of a 110-lb light fixture that fell onto a Central Artery tunnel roadway in early February. The Massachusetts Bay Transportation Authority informed the public about the incident last week. “One of the 23,000 light fixtures in the Central Artery Tunnel system fell onto the roadway on the morning of February 8,” says a spokesperson for the MBTA. Although there were no injuries or property damage, the incident has reignited concerns about safety of the $2 billion project. The Massachusetts Dept. of Transportation claims it immediately began to inspect all of
