Nuclear

U.S. optimism has been restored by reports of abundant, reasonably priced natural gas to fuel most new generation; however, huge gaps in the fuel delivery system (thousands of miles of pipelines are needed) will soon challenge gas plant development. Meanwhile, the cloud of sovereign debt hangs over all major capital projects in Europe, where the UK moves ahead with new nuclear projects while many of its neighbors shut the door on nuclear and struggle to finance their commitment to renewables.

The technologies used to generate and distribute electricity will be radically transformed during the coming decade. Amid that change, the power industry must continue to meet customer reliability, safety, and cost-of-service expectations. Achieving the right balance among these often-conflicting goals is the primary focus of every utility. The Electric Power Research Institute is helping utilities achieve that balance with R&D programs for many new and emerging technologies.

The Five-Year Plan is the expression of the centralized planning goals for China’s economy. The 12th Five-Year Plan, approved by the Chinese Government on March 14, 2011, established many social and economic goals, including significant expansion of the country’s power generation industry in many new directions.

Tokyo Electric Power Co.’s (TEPCO’s) Fukushima Daiichi 1 reactor—a unit that suffered a core melt and hydrogen gas explosion after the March 11 earthquake in Japan and subsequent tsunami devastated the six-reactor facility—was fully encased in an “airtight” cover in October.

South Africa is at a critical turning point. An uncertain environment for private investment, escalating electricity prices, and a lack of available power threaten South Africa’s position as an attractive investment destination for many of the country’s most important industries. Power has been placed at the forefront of the government’s agenda, but South Africa needs a collaborative effort to meet the country’s energy demands and diversify its generation portfolio in order to drive economic growth.

The International Thermonuclear Experimental Reactor (ITER) in southern France, the world’s biggest nuclear fusion research project, is seeing a revival. After a budget shortfall last year and cost projections that continue to escalate, in September, the project got the European Parliament’s (EP’s) backing for an autonomous budget that seeks to guarantee transparent and reliable financing while limiting cost overruns. Japan also announced that it would increase its budget for ITER by 50% (the current ITER director-general is Japanese). Also in September, scientists announced that after an 18-month shutdown to upgrade the Joint European Torus (JET)—the world’s largest magnetic fusion device—the machine is ready to test materials to be used inside ITER (Figure 5).

For seven years in a row, the number of new nuclear construction starts increased markedly. Then the accident at Japan’s Fukushima Daiichi plant occurred, prompting shutdowns of existing plants and a rethinking of future plans in many countries. Nevertheless, the International Atomic Energy Agency (IAEA) expects “continuous and significant growth” in the use of nuclear […]

The global nuclear industry is moving forward at a brisk pace, only slightly slowed by the Fukushima Daiichi accident. The International Atomic Energy Agency’s most realistic estimate is that 90 new nuclear plants will enter service by 2030. Ten new nuclear plants went online over the past two years. We profile four of them as POWER’s nuclear Top Plants for 2011.

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.

One of the great successes of the power generation industry over the past two decades has been the significant increase in nuclear plant reliability and other performance standards. However, there is reason to be concerned that the design, operation, and maintenance practices used by the current fleet of plants do not leverage all the possible advantages from a digital controls upgrade. Perhaps past success is the biggest barrier to future success.
