Radioactive materials are clinging to the inside walls of reactor system components because of a noble metals injection process error some years ago at Cooper Nuclear Station (CNS). CNS has launched an aggressive, long-term program to remove the materials, but until the work is successfully completed, the station is also taking extensive measures to protect employees and reduce higher source term dose.

The expanded line of CoolPoint vortex shedding flowmeters introduced recently by Universal Flow Monitors Inc. is designed to ensure flow consistency in hydroelectric generators, heat exchangers, boiler feed pumps, steam turbines, natural gas humidification, and process cooling applications where water quality may be less than optimal. Additions to the product line include four larger sizes […]

Dickson’s new stainless steel case data loggers are designed to monitor up to 275F in wet conditions. The watertight instruments are made of stainless steel and are available in three models: HT 200 (the "Takes-the-Heat-Watertight" model) and piercing probe models HT 220 and HT 225. All models are available with user-replaceable one-year batteries and USB-enabled […]

The GRAPHLON GM 860 developed by Graphite Metallizing is an abrasion-resistant bushing material that protects pumps and helps prolong pump life. Designed for use in the manufacture of pump bushings and other critical-wear parts, the tough, polymer/graphite-based material was developed to replace traditional pump materials, which are prone to damage from highly abrasive suspensions. It […]

This year’s ELECTRIC POWER Exhibition will feature the latest technologies and services from approximately 500 companies. Get a preview of some of the exhibitor offerings here. For the entire offerings, you’ll have to visit the show floor in Chicago this May. (You’ll find all the event information here.)

The Environmental Protection Agency has ordered a review of some 300 U.S. utility coal combustion waste sites and said it will develop new regulations to ensure that incidents like December’s colossal coal ash spill in Kingston, Tenn., are not repeated.

Environmental Protection Agency Administrator Lisa Jackson has said that the EPA will reconsider a controversial policy memorandum issued by the agency late last year stating that the agency would not establish a carbon dioxide emission standard for new power plants and other large industrial sources of the heat-trapping gas.

In the face of growing criticism from congressional Democrats of his plan to require electric utilities and other industries to pay for greenhouse gas emission allowances, President Obama told business leaders he is willing to negotiate on the issue, but warned that broad, free allowance allocations would mask the carbon price signal economists say is crucial to speed the deployment of clean technologies needed to fight global warming.

Circulating fluidized bed technology has the potential to significantly reduce carbon emissions when burning coal and adds the additional flexibility of burning other renewable fuels. Foster Wheeler’s Flexi-Burn technology allows the CFB to produce a CO2-rich flue gas and be part of a practical carbon capture and storage solution.

Conventional wisdom tells us that the key to good boiler combustion requires carefully balancing the fuel-air ratios across all the coal pipes. Recent tests show that the uniformity of the burner-to-burner stoichiometries—not balanced pipe-to-pipe fuel flow distributions—dictates combustion uniformity.
