In addition, since these structures are designed for a maximum ground acceleration of 0.3g, the overall and local design of these structures are not expected to be governed by hurricane. Residual heat transferred to the atmosphere, 11 systems eliminated from previous designs, 25 percent of pumps, valves and motors eliminated. It has the lowest core damage frequency (industry standard measure of safety) of any Generation III or III+ reactor and can safely cool itself with no AC electrical power or human action for more than seven days. %PDF-1.4 %���� Using natural circulation, the ESBWR has 25 percent fewer pumps and mechanical drives than existing active safety plants. The ESBWR is designed to generate electricity while producing nearly zero greenhouse gas emissions during operation. In the USA, the federal Department of Energy (DOE) and the commercial nuclear industry in the 1990s developed four advanced reactor types. endstream endobj 239 0 obj <> endobj 240 0 obj <> endobj 241 0 obj <>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC]/ExtGState<>>> endobj 242 0 obj [/ICCBased 247 0 R] endobj 243 0 obj <> endobj 244 0 obj <>stream ABWR to ESBWR evolution: Nuclear Island 1 1 1 High Pressure Core Flooder 2 Fuel and Aux Pool Cooling – equivalent designs Reactor Water Cleanup System – equivalent designs 2 2 3 3 3 9Suppression Pool Cooling & Cleanup System –equivalent capability 7 –replaced by HP CRD makeup 0000001119 00000 n endstream endobj 245 0 obj <> endobj 246 0 obj <> endobj 247 0 obj <>stream 0000033657 00000 n It is projected to have the lowest operating, maintenance and staffing costs per megawatt hour of any reactor technology available today. There are around 33 operating BWRs in the US out of approximately 100 nuclear stations in service, and they form the majority of the Japanese fleet – the global total is around 90 units The most obvious difference between a BWR and a PWR is apparent in the name. The ABWR is a single-cycle, force-circulation, boiling-water reactor (BWR), with a rated power of 3926 MWt, designed by GE Nuclear Energy. Compared to typical generation on the U.S. grid, the electricity produced by an ESBWR would avoid the emission of approximately 7.5 million metric tons of CO2 per year. ITS will also be used outside the U.S. by AREVA, Toshiba/Westinghouse, GE-Hitachi and Mitsubishi. • The AP1000, ESBWR and EPR represent very different designs with new passive design features. The ABWR is a design that has already been proven with more than 18 reactor years of operating data from plants completed in Japan in the mid-to-late 1990s. 0000001558 00000 n The advanced boiling water reactor (ABWR) is a Generation III boiling water reactor.The ABWR is currently offered by GE Hitachi Nuclear Energy (GEH) and Toshiba.The ABWR generates electrical power by using steam to power a turbine connected to a generator; the steam is boiled from water using heat generated by fission reactions within nuclear fuel. Using natural circulation, the ESBWR has 25 percent fewer pumps and mechanical drives than existing active safety plants. So we have with serial production of ESBWRs a cost of $5 billion per GW, not terrific, but not bad either, TransAtomic Power believes they can lower nuclear costs to $3.4 per GW, while Terrestrial Energy expects to take it even lower. BWR Type 1 (BWR-1, BWR/1): In 1955 GE … 0000002193 00000 n The ESBWR program inherited a technologically rich legacy of design, development, and analysis work passed along from the SBWR and ABWR programs. • Four ABWRs have been built in Japan. :b�~��`R��ug���F�k%�����q��n`� iO��1Y�tV��2�-��l1��i �-�8�]>�+��[yM�@R����`A�'S��Oc��{tz��?�z+�Y�V/yx(r�:�����'[�}��o��?�'��,ܮ�pL(h�jQ�ē��]�A�����*����h``RҌb �8.P�c���Z�t �I5,��Q���Q��LM"!���^�gS�4/��-Re�g8��4�#CC W�}�3��/`�pn���)����F�V.� ��L�\�n W�����t��a���ZtX^}� lzH3��ev����@� �ד� ESBWR.

It requires action and new work for it to be addressed. Now GE has just ESBWR in the US and no ESBWR has been built anywhere in the world, unlike ABWR.

GE’s link for the ESBWR The third is GE’s latest design, the Economic Simplified Boiling Water Reactor (ESBWR) which just received its Final Design Approval from the NRC on October 15, 2014. It also has fine motion control rod drives. ABWR: Higher safety margins, no external recirculation loops, reactor internal pumps. In addition, EXCEL is currently supporting the development and licensing of ITS for the very first AREVA EPR The ABWR has an impressive track record.
