Abstract

An innovative reactor core concept applying spectral shift rods (SSRs) is proposed to improve the plant economy and the operability of the 1700 MWe ABWR-II reactor. The SSR is a new type of water rod, in which a water level is naturally developed during operation and changed according to the coolant flow rate through the channel. By taking advantage of the largeness of the ABWR-II bundle, the enhanced spectral shift operation by eight SSRs allows operation of the ABWR-II with all control rods withdrawn. In addition, the uranium saving factor of 6-7% against the reference ABWR-II core with conventional water rods can be expected owing to the higher spectral shift effect. The combination of these advantages means the ABWR-II with SSRs should be an attractive alternative for the next generation nuclear reactor. (authors)

ABWR-II Core Design with Spectral Shift Rods for Operation with All Control Rods Withdrawn

Journal Article Moriwaki, Masanao; Aoyama, Motoo; Anegawa, Takafumi; ... - Nuclear Technology

An innovative reactor core concept applying spectral shift rods (SSRs) is proposed to improve the plant economy and the operability of the 1700-MW(electric) Advanced Boiling Water Reactor II (ABWR-II). The SSR is a new type of water rod in which a water level is naturally developed during operation and changed according to the coolant flow rate through the channel. By taking advantage of the large size of the ABWR-II bundle, the enhanced spectral shift operation by eight SSRs allows operation of the ABWR-II with all control rods withdrawn. In addition, the uranium-saving factor of 6 to 7% relative to themore »« less
Large Bundle Design and its Development for ABWR-II

Conference Moriwaki, Masanao; Chaki, Masao; Aoyama, Motoo; ...

The next generation ABWR, the ABWR-II, has been under development for more than a decade in Japan. Among various features newly adopted for the ABWR-II, a 1.5 times lager fuel bundle is notable. This bundle design makes it possible to increase the total number of fuel rods in the core while minimizing the reactor pressure vessel size increase. Also, the number of fuel bundles in the core will be reduced to almost half that of the ABWR. Due to larger cruciform control rods and the K-lattice configuration, in which a bundle faces two control rods along all four faces, themore »« less
Development of advanced BWR fuel bundle with spectral shift rod - BWR core characteristics with SSR

Conference Hino, T.; Kondo, T.; Chaki, M.; ...

The neutron energy spectrum can be varied during an operation cycle to generate and utilize more plutonium from the non-fissile {sup 238}U by changing the void fraction in the core through control of the core coolant flow rate. This operation method, which is called a spectral shift operation, is practiced in BWRs to save natural uranium. A new component called a spectral shift rod (SSR), which is utilized instead of a conventional water rod, has been introduced to amplify the void fraction change and increase the spectral shift effect. In this study, fuel bundle design with the SSR and coremore »« less
Evaluation of Stability and Transient Characteristics of ABWR-II Large Bundle Core and SSR Influence for Transient phenomena by TRACG Code

Conference Masao, Chaki; Hideo, Soneda; Shinya, Mizokami; ...

The next generation ABWR, the ABWR-II, has been under development for more than a decade in Japan. Among various features newly adopted for the ABWR-II, a 1.5 times lager fuel bundle is notable. This bundle design makes it possible to increase the total number of fuel rods in the core while minimizing the reactor pressure vessel size increase. As a result, the void coefficient is more negative due to the harder neutron spectrum since a smaller hydrogen-to uranium (H/U) ratio with fuel inventory increase makes the neutron spectrum harder. This more negative void coefficient affects the stability and transient characteristicsmore »« less
The status of ABWR-II development

Conference Hiroyuki, Okada; Kitamura, Hideya; Kumiaki, Moriya; ...

This paper reports on the current development status of the ABWR-II project, a next generation reactor design based on the ABWR. In the early 90's, a program to develop the next generation reactor for the 21. century was launched, at a time when the first ABWR was still under construction. At the initial stage of this project, development of a 'user friendly' plant design was the primary objective. Thus, the main focus was placed on selecting a design with features promoting ease of operation and maintenance. Meanwhile, the circumstances surrounding the Japanese nuclear power industry changed.
