Callaway Nuclear Power Plant

Ameren's Callaway nuclear power plant produces about 19 percent of the electricity the company generates in Missouri. It is the only nuclear energy facility in the state.

Starting this week, Ameren will have a new way to store radioactive waste at its Callaway nuclear power plant near Fulton.

It’s called dry cask storage.

Ameren is not moving forward with plans for a second reactor at its Callaway Nuclear Power Plant in mid-Missouri near Fulton. Ameren's application for a second reactor at Callaway was filed with the Nuclear Regulatory Commission in 2008.  But funding issues hampered the project. State lawmakers have balked at the utility's efforts to allow Ameren to charge customers for the facility as it was being built.

During a conference call Friday morning with analysts, Chief Executive Officer Warner Baxter cited several reasons for the decision to pull the plug.

The Missouri Coalition for the Environment filed a federal lawsuit Thursday over a federal agency’s renewal for Ameren’s Callaway Nuclear Power Plant.

The Nuclear Regulatory Commission has renewed the operating license for Ameren's Callaway nuclear power plant through 2044.

But ongoing litigation could quash that renewal.

The Missouri Coalition for the Environment has filed a petition to intervene with the Nuclear Regulatory Commission to try to keep the NRC from relicensing Ameren's Callaway Nuclear Power Plant.

The Missouri Coalition for the Environment is one of several groups filing suit against the U.S. Nuclear Regulatory Commission to try to get the agency to address the long-term storage of nuclear waste.

That suit follows similar cases filed by the states of New York, Connecticut, and Vermont, the Natural Resources Defense Council, and the Prairie Island Indian Community in Minnesota.

Missouri lawmakers are sounding off on proposed Environmental Protection Agency rules aimed at reducing carbon emissions.  

The proposed rules effectively provide individual states with options to reduce carbon emissions by 2030. These options include making facilities more energy efficient, investing in alternative energy sources like solar and wind power, or joining other states in “cap and trade” programs.

Missouri's sole nuclear power plant is back online after being shut down for more than three weeks.

Ameren Missouri's Callaway Energy Center was taken off line July 26 after an electrical arc caused a small fire.  The plant resumed operations Sunday morning.  Spokesman Cleve Reasoner says the arc was triggered when a ventilation louver came loose and got too close to the power cables.

"Testing confirmed that there was no impact to the major components," Reasoner said. "So the repairs were those that were associated directly with correction of the arc damage."

Missouri's lone nuclear reactor remains shut down while workers and officials continue to investigate what caused a small fire at the Callaway County plant Friday night.

Ameren Missouri spokesman Cleve Reasoner said it'll be several days before the plant is back online.

"We are assessing impacts from the arc that we had in our cable leading from the plant," Reasoner said. "We've begun disassembling equipment and investigating what the nature of the damage is and what the nature of the cause(s) of the event are."

Ameren-Missouri officials say a small fire in a turbine building last night has prompted them to temporarily shut down the nuclear power plant near Fulton, Mo.

The fire was put out quickly, no injuries have been reported and at no time did the situation threaten the public or nearby communities, according to a statement released by Ameren-Missouri.

According to an Ameren-Missouri release:

Ameren Missouri released a statement today saying that the plant is operating safely, but did not release any further details about those injured. An excerpt of the statement: 

A collaboration between St. Louis-based Ameren Missouri and Westinghouse Electric Corporation to develop small modular nuclear reactors was passed over Tuesday for initial

funding by the U.S. Department of Energy.

The DOE will, instead, fund a similar project by Babcock & Wilcox and the Tennessee Valley Authority. The Ameren/Westinghouse partnership was seeking $452 million in funding to build the SMR's alongside the utility's Callaway county reactor.

Together with its partner in the venture, Westinghouse Electric Company, Ameren held what it called a “supplier summit” today in St. Louis.

Ameren's request to renew the operating license for its Callaway Nuclear Power Plant with the U.S. Nuclear Regulatory Commission, for the next 20 years, has garnered another legal challenge.

Ameren, Westinghouse to give more details on nuclear partnership

Missouri regulators will learn more today about a proposal to build small nuclear reactors at Ameren Missouri's Callaway nuclear power plant.

Updated 2:15 p.m. with link to full legal document.

A St. Louis-based environmental group is asking the federal government to more closely scrutinize Ameren Corp.'s request for a 20-year license renewal at Missouri's only nuclear power plant.

Westinghouse Electric Corporation and St. Louis-based Ameren Missouri will collaborate on developing small modular nuclear reactors, or SMR’s, and will seek to build them at Ameren’s Callaway County plant.

Westinghouse officials say they’ll apply for $452 million in federal funding.  Plans are to build at least one and possibly five SMR's alongside Callaway’s current reactor, and to build more SMR’s at the site for export.  Governor Jay Nixon (D) described the economic potential as enormous.

Tests on infant formula find no trace of deadly bacteria

Illinois-based Mead Johnson says another batch of tests done on its Enfamil Premium Newborn infant formula found no trace of the bacteria tied to the death of a Missouri baby.

Preliminary hospital tests indicated 10-day-old Avery Cornett died Dec. 18 of a rare infection caused by bacteria known as Cronobacter sakazakii. The source of the bacteria hasn't been determined, but it can be found in powdered formula. Avery had consumed Enfamil Newborn formula.


City Corrections Commissioner suspended hours before jail break

Hours before an inmate escaped from a St. Louis jail on Friday night, the city's corrections commissioner was suspended because of complaints about his management of city jail facilities. Commissioner Gene Stubblefield will be able to defend his performance in several hearings and meetings. The city emphasized that no one is alleging any criminal misconduct.

Legislation that would allow Missouri utility customers to be billed for a site permit for a second nuclear reactor may be dead for the session.

The measure had recently been added to a separate bill dealing with utility deposits and the Office of Public Counsel.
