The U.S. Department of Energy contracted Shaw AREVA MOX Services LLC to design, construct, and operate a Mixed Oxide (MOX) Fuel Fabrication Facility (MFFF) at its Savannah River Site in South Carolina. The MFFF will convert depleted uranium and excess weapons-grade plutonium stockpiles, equivalent to approximately 17,000 nuclear weapons, into MOX fuel assemblies that will be used in U.S. nuclear power plants by 2018.

Small reactors are big news, particularly the 180-MWe Generation III++ Babcock & Wilcox mPower small modular reactor (SMR). This SMR has all the features of its larger cousins, but the entire reactor and nuclear steam supply system are incorporated into one reactor vessel, all about the size of single full-size pressurized water reactor steam generator. Expect the first mPower—and probably the first SMR—to enter service before 2022.

In February 2012, the Nuclear Regulatory Commission approved two combined construction and operating licenses for Southern Nuclear’s Plant Vogtle Units 3 and 4 in Georgia. They were the first licenses ever approved for a U.S. nuclear plant using the one-step licensing process and the first allowing construction in more than three decades. Now the real work begins.

Ongoing investigations into cancellation of the Yucca Mountain project have revealed an astonishing number of irregularities by agencies responsible for the project. Those investigations have exposed a broken system that failed to properly manage the project and that surrendered to political pressure. Worse still, the draft report of President Obama’s Blue Ribbon Commission on America’s Nuclear Future gave the industry little reason to hope that there would ever be a long-term nuclear waste fuel repository.

PRISM is an advanced sodium-cooled reactor that simultaneously reduces proliferation concerns by consuming transuranics and weapons-grade plutonium and closes the nuclear fuel cycle. PRISM’s passive safety systems, successfully demonstrated in earlier liquid metal reactor programs, combined with modern design requirements, make PRISM invulnerable to most serious accidents that can affect light water reactors.

In 1983, OSHA published its Hazard Communication (HAZCOM) Standard, which requires that the hazards of all chemicals used in the workplace be communicated to employees so that responsible protective measures can be taken. Today, HAZCOM remains near the top of the list of most frequently violated OSHA standards that result in a citation. The 1917 Halifax Explosion, one of the world’s largest nonnuclear explosions, testifies to what can happen when you don’t have—or don’t follow—an effective HAZCOM program.

The commercial nuclear industry is in the midst of developing multiple reactor technology options. Next in our series of articles exploring competing reactor technologies are GE Hitachi Nuclear Energy’s Advanced Boiling Water Reactor (ABWR) and Economic Simplified Boiling Water Reactor (ESBWR). The design improvements incorporated into these reactors include passive safety systems, design and construction simplification, and component standardization to reduce construction and operating costs.

The refurbishment and restart of all four CANDU reactors at Bruce A may be Ontario’s most significant and complex power generation project since the first phase of the Bruce Nuclear Generating Station was built more than 30 years ago. Units 1 and 2 are expected to be synchronized in 2011 and return to commercial service by early 2012, joining Units 3 and 4, which restarted in 2004 and 2003 respectively. POWER visited Bruce A in April to witness the project’s progress.

The Nuclear Waste Policy Act and Amendments of 1982 and 1987 established a national policy and schedule for developing geologic repositories for the disposal of spent nuclear fuel and high-level radioactive wastes. Those deadlines have come and gone; the cancellation of Yucca Mountain was only the latest failure of this policy to become reality. The task of finding a new storage location is now a political committee’s homework assignment. History tells us that committee members have been given an impossible task.

In August 2009, the Nuclear Regulatory Commission (NRC) issued its fourth Early Site Permit for two new units at Southern Nuclear’s Vogtle site and its first for the Westinghouse AP1000 pressurized water reactor design. The two new units planned for Vogtle also became the reference plant for the AP1000 under NuStart in June 2009. This means Vogtle Units 3 and 4 will be the first licensed installations of the new AP1000 reactor design in the U.S. Plant Vogtle is expected to get the NRC’s approval to begin construction in 2011.
