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 late January, a 1.5-MW concentrating solar power (CSP) plant began providing power to Salt River Project customers in Greater Phoenix, Ariz. Though small, the plant, developed by Tessera Solar and Stirling Energy Systems (SES), is seen as a prelude to 1,500-MW projects that are due to break ground in California and Texas later this year.

Nearly every combined-cycle operator recognizes that cycling reduces the life expectancy of hot-gas-path components in combustion turbines. Often overlooked, however, is that the same phenomenon affects the heat-recovery steam generator (HRSG).

The "combined" portion of a combined-cycle plant is the heat-recovery steam generator (HRSG) that generates high-pressure and high-temperature steam and the steam turbine generator that expands the steam to produce electricity. Integrating the HRSG and steam turbine with the combustion turbine is a key challenge for plant designers, as each system has differing operating profiles, operational constraints, and design requirements.

Early last year, there were promising signs that electric transmission line construction would be facilitated by the convergence of the new administration’s emphasis on developing remote renewable generation resources, proposed legislative provisions expanding federal siting authority, and the granting by the Federal Energy Regulatory Commission (FERC) of generous cost-of-service returns on such investments. However, the stars did not align for transmission policy in 2009 as had been hoped, and the forecast is cloudy.

CAT PUMPS recently introduced two new stainless steel triplex plunger pumps featuring a 316 stainless steel liquid-end for corrosion resistance. The 7CP6111 and 7CP6171 are designed for pumping liquids like seawater in small seawater reverse osmosis installations, demineralized water for misting, or hot water and sanitizers for sterile cleaning systems. The 7CP stainless steel pumps […]
