TOP PLANT: Beloyarsk Nuclear Power Plant Unit 4, Sverdlovsk Oblast, Russia
Owner/operator: Rosenergoatom Fast-neutron reactors are pivotal to Russia’s ambitious nuclear power plans. The successful construction, grid-connection, and testing of the country’s first BN-800 reactor at its Beloyarsk nuclear plant is a major achievement in the right direction. Since the Soviet Union began its first experimental nuclear power projects in the 1940s, Russia has embraced nuclear’s […]

Japan Kills Monju but Not Breeders
In a widely expected move, the Japanese government finally killed the ill-fated Monju breeder reactor project on September 21, but reasserted its faith in breeder reactor technology as a component of the nation’s future power mix. The Monju plant was an ambitious project that never came close to meeting its backers’ expectations. Launched in 1980, […]

HRSG Condition Assessments Identify CAPEX, Maintenance Priorities
As combined cycle gas turbine plants are called upon to play a larger and more flexible role in the generation mix, it’s important to schedule a comprehensive assessment of major components at key intervals to ensure reliable operation. Just like humans, power plants can benefit from regularly scheduled condition assessments, which are sometimes called “health […]

Efficient Use of Power Plant Process Data Improves Asset Management
Asset data is crucial in the power generation industry. Without it, utilities are forced to speculate about how long their assets will last, when they will need repair, and which strategies will maximize plant efficiency. With it, plant owners have the tools to drive down operational and maintenance costs while ensuring highly reliable power delivery. […]
