German Court Questions Legality of Nuclear Tax
A German finance court in September questioned the constitutionality of a controversial tax on fuel used in nuclear power plants, a decision that could influence rulings in various finance courts around the country that are reviewing complaints by nuclear operators regarding the levy.

NewsEmergency Lighting Solution
BIRNS introduced what it is calling the “world’s most advanced, seismically qualified (per IEEE-344) emergency lighting solution” for nuclear containment: the BIRNS Emergency Light Fixture-LED. The slim-profiled, wall-mounted system provides in excess of 24 hours of continuous, brilliant LED light in the case of power loss in nuclear power facilities and is capable of withstanding […]

NuclearITER Gets New Life
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).

THE BIG PICTURE: Reactors Under Construction
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 […]

Hazard Recognition and Control: Improving Safety’s Bottom Line
The power generation industry is a highly competitive one in which players continue to change and the race for profits is a tough one with the challenge of heavy environmental regulations. One of the most overlooked areas for cost savings is safety. Notwithstanding the moral and legal responsibilities that power plant management has for creating a workplace where everyone can work without injury, reducing and eliminating workplace injuries and illnesses is good for business.

O&MSteam Turbine Cleaning Using Chemical Foams
In the May issue, we discussed the importance of either preventing copper plating of the high-pressure (HP) steam turbine rotor or finding a good foam or mechanical removal means of restoring lost efficiency. In that article we noted that “copper deposits typically form on the stationary nozzle block or first-stage stationary blades” and that those deposits usually result in a steam turbine loss of capacity at a rate of about 2 to 3 MW per month. We also stated that the “general rule of thumb is that there is a reduction of about 1 MW of generating capacity for each 1 to 2 pounds of deposit that accumulates on the HP turbine.

Improving Condenser O&M Practices
Losses attributed to condenser tube leaks, fouling, and failures continue to climb, costing the power generation industry an estimated half-billion dollars annually in maintenance costs and loss of production. Investing in an effective condenser maintenance program will reduce those expenses in short order.
