C&EN: COVER STORY - NUCLEAR POWER FOR THE FUTURE These new types of reactors are often described as "evolutionary" or "revolutionary." The evolutionary systems, known as generation III and III+ systems, have designs that evolved from the generation II fleet of reactors that were built in the 1970s and 1980s and continue to operate today. Generation I and II reactor safety systems are "active" because they rely on active electrical and mechanical control of equipment such as sensors, valves, pumps, accumulators, heat exchangers, and backup power supplies. The new systems range from a supercritical-water-cooled reactor (SCWR), which operates at 510–550 °C, to a helium-cooled very-high-temperature gas reactor (VHTR), which has an operating temperature of 1,000 °C. SCWR is the only one of the six generation IV technologies that is cooled by water. pubs.acs.org /cen/coverstory/8237/8237nuclearenergy.html   (3871 words)

Unique Reactors The BORAX II reactor, a Boiling Water Reactor (BWR) prototype was used. It is currently being used to support the development of the Generation IV reactors for the U.S. Department of Energy, and it will be contributing to NASA's space program. In addition to the reactor, a container was needed for the control room, another for the heat conversion system, and a total of three boxes for the cabling, auxiliary gas storage and handling equipment, and tools and supplies. eia.doe.gov /cneaf/nuclear/page/nuc_reactors/superla.html   (3085 words)

Phase II of nuke power generation begins It is also developing 100 kw Thermal compact temperature reactor to address the needs of remote areas in the country which are not connected to grid system while it has almost completed the construction of Advanced Vitrification system to immobilize the high level radioactive waste from nuclear power plant at Tarapur using Joule Melter technology. The year, which marked completion of 50 years of the existence of the Department of Atomic Energy (DAE), saw considerable development towards setting up of country's first 500 MW Prototype Fast Breeder Reactor (PFBR), a beginning of the second phase of nuclear energy programme. For the third stage of programme, envisaged keeping in mind the vast thorium reserves, the Advanced Heavy Water Reactor - a proliferation resistant reactor which is being developed by the Bhabha Atomic Research Center, is currently undergoing a safety review while the peer review has already been completed. web.mid-day.com /news/city/2003/december/71763.htm   (3085 words)

Reactors: Modern-Day Alchemy Experimental Breeder Reactor II was the first reactor to contain, as an integral part, a fuel reprocessing system that allowed spent uranium fuel to be removed from the sodium-cooled reactor, purified and made into new fuel elements, and then replaced into the reactor-- the ultimate recycling, energy-saving, and waste management system. Work on this next generation of fast reactors-- clean, resource-efficient, waste-reducing reactors-- was halted by Congress in September 1994 as the laboratory's mission was redirected by the Department of Energy into the development of electrometallurgical technology for DOE spent fuel treatment, reactor and fuel cycle safety, and decontamination and decommissioning technology. Experimental Breeder Reactor II and its primary system components -- including pumps, heat exchanger, instrumentation, and fuel handling system -- were submerged in a large tank of sodium during operation. www.anl.gov /Science_and_Technology/History/Anniversary_Frontiers/alchemy.html   (1507 words)

Utility, Industry, and Corporation News, January-February 1996 France, specializes in nuclear devices for remote handling, especially the new generation heavy manipulator arms such as CONDOR II. Plant 2's actual net generation of 6.9 million mega-watt hours of electricity during 1995 was second only to the 7.1 million net megawatt-hours generated in 1993. The nuclear power plant needed to move a one million pound steam generator to a location near the reactor assembly. npj.goinfo.com /NPJMain.nsf/0/bb0b2cbd517beb888525645100284761?OpenDocument   (1507 words)

Nuclear submarine emergency in floating dock during decommissioning A first generation Echo-II class nuclear submarine fell on its portside in a floating dock during decommissioning at a naval shipyard at the Kola Peninsula. Reactor compartments from Polyarny and other shipyards at the Kola Peninsula and in Severodvinsk, Arkhangelsk county, are towed to Sayda Bay, located not so far from Polyarny. In 2000, the civilian nuclear support ship Imandra was working at Polyarny defuelling two Victor-II submarines. www.diodon349.com /Stories/nuclear_submarine_emergency_in_floating_drydock_Russia.htm   (966 words)

Russia A chain reaction occurred in one of the two reactors on the Echo II, damaging the reactor's fuel rods and causing high levels of radiation in the reactor compartment. On 21 December 2001, Bellona reported that the Imandra service ship had defuelled the Victor III-class submarine K-254 at the Polyarninskiy Shipyard in November. Polyarninskiy repaired approximately 250-first generation nuclear submarines from 1962 to 1993, and is Murmansk Oblast's only shipyard capable of servicing second and third generation submarines. www.nti.org /db/nisprofs/russia/naval/nucflt/norflt/polyarny.htm   (966 words)

CANDU news at nuclear.com CANDU reactors emerged from World War II nuclear weapons research at Chalk River, Ont. Designed for plutonium production, they employ heavy water to allow the use of un-enriched uranium fuel. CANDU fuel rods, which can be removed and inserted during reactor operation, have a much shorter usable life span than the enriched uranium fuel rods used in light water reactors. The CANDU, with features such as on-load refueling to avert the most common cause of routine reactor downtime, is in many ways a great success, not only in Canada but also in Argentina, China, Romania, and South Korea. www.nuclear.com /n-plants/index-CANDU_news.html   (345 words)

Polyarny One of them, a first-generation Echo II, contains a damaged reactor with high radiation levels in the reactor compartment. Navy Yard No. 10 Shkval [Squal], located on the western side of the Murmansk fjord, has about a half-dozen decommissioned nuclear submarines. ANNEX B.

TransWare DOE-SBIR Grant Application for TransFX The geometry modeling technique shall allow for the accurate representation of all known nuclear fuel assembly and reactor component designs used in Generation II, III, and IV reactors. The flexible geometry modeling technique must be capable of modeling the highly heterogeneous designs proposed for Generation IV reactors. The problems that arise from the different modeling techniques are: (1) each technique uses a different interface for passing ray-tracing data from the geometry processing to the transport calculation modules; and (2) the techniques commonly employed in deterministic transport codes are based on two-dimensional geometries. www.twe.com /www/TFXMAN/TFX-doe_sbir-grant_app.html   (345 words)

Kalpakkam plant cleared to resume power generation - Sify.com Chennai: The Atomic Energy Regulatory Board (AERB) has cleared Unit-II of the Madras Atomic Power Station (MAPS) at Kalpakkam for resumption of power generation. When the tidal waves struck the Kalpakkam coast, Unit-2 was operating at its authorised power, but when water entered the pump house, it "tripped and the reactor was brought to a safe shutdown state," he said. AERB secretary Dr Om Pal Singh said in a release on Thursday that a five-member senior level team had inspected the nuclear facilities at Kalpakkam, including the Fast Breeder Test Reactor at the Indira Gandhi Centre for Atomic Research (IGCAR), and it was observed that there had been no impact on these facilities. sify.com /news/fullstory.php?id=13639875   (189 words)

Angra Nuclear Power Plant - Wikipedia, the free encyclopedia It consists of two Pressurized water reactors, Angra I, with a net output of 626 MWe, first connected to the power grid in 1982 and Angra II, with a net output of 1275 MWe, connected in 2000. As a result, Angra II was built with German technology, as part of a comprehensive nuclear agreement between Brazil and West Germany signed by President Ernesto Geisel in 1975. Angra I was purchased from Westinghouse of the USA, and the purchase did not include the transfer of sensitive reactor technology. en.wikipedia.org /wiki/Angra_Nuclear_Power_Plant   (390 words)

Chap. 2: Nuclear-powered vessels - The Russian Northern Fleet In addition, a first generation liquid metal cooled reactor on board the submarine K-27 broke down in 1968. The first generation Soviet naval submarines included: Project 627 A - November class, 658 - Hotel class, 659 - Echo-I class and 675 - Echo-II class. Construction of this class of vessels will probably begin in 2002-2004 at the Severodvinsk shipbuilding yard, and they will then enter service from 2006-2008.[ 99 ] These submarines will probably be fitted with both strategic and cruise missiles with multiple nuclear warheads.[ 100 ] spb.org.ru /bellona/ehome/russia/nfl/nfl2-1.htm   (390 words)

AnnexI In addition, a development programme was started in 1991 for ABWR-II, aiming to further improve and evolve the ABWR, with the goal of significant reduction in power generation cost relative to a standardized ABWR. Future ABWRs are expected to achieve a significant reduction in generation costs relative to the first ABWRs. LWRs include pressurized water reactors (PWRs), boiling water reactors (BWRs), advanced boiling water reactors (ABWRs), and the Russian type pressurized water reactors (WWERs). www-pub.iaea.org /MTCD/publications/PDF/cnpp2003/CNPP_Webpage/pages/AnnexI/AnnexI.htm   (7271 words)

Under way on Nuclear Power The power plant of a nuclear submarine is based upon a nuclear reactor which provides heat for the generation of steam. Mark I (Nautilus was known as STR Mark II) was built from the start inside a submarine hull, complete with a surrounding tank of water, on the assumption that it was a true seagoing power plant. The reliability of Nautilus’ nuclear propulsion plant was considered to be due in large measure to the experience gained in the construction and operation of the land prototype plant. www.rddesigns.com /saga/nucs.html   (3925 words)
