Book excerpt: Recent tests in the Experimental Breeder Reactor II (EBR-II) have demonstrated that reactor feedbacks can passively reduce power and thus effectively mitigate reactor undercooling caused by equipment failures. A follow-on testing program is being designed to investigate the use of these feedbacks along other liquid metal reactor (LMR) characteristics to routinely control reactor power during plant maneuvers and fuel burnup, compensation, and to limit the possibility and consequences of over-power accidents. In all of the tests described in the present paper, the control rods will not be used as the plant is maneuvered over the power range between 40 and 100%. The plant variables (forcing functions) employed in the power control include the primary flow, the secondary flow, and the turbine admission position. The pretest predictions for the tests are presented and a preliminary analysis on the effects of controller failures is discussed. This paper provides concepts in reactor power control which may lead to fundamental changes in design and safety consideration of metal fueled LMRs.

Available in PDF, EPUB and Kindle. Book excerpt: A group of five plant inherent control tests was successfully conducted in November 1987 in the Experimental Breeder Reactor II. These tests demonstrated that the plant power of a metal-fueled reactor can be passively controlled over a large power range by slowly changing the primary flow and the reactor inlet temperature. These variables are, in turn, regulated by the primary pump speed, the secondary flow, and the turbine inlet pressure. In all tests, control rods were not used to regulate power. It was demonstrated that the plant power can be controlled with reasonable accuracy without using control rods when the reactivity feedback characteristics of the reactor are well understood and the plant controllers are adequately designed.

Available in PDF, EPUB and Kindle. Book excerpt: On April 3, 1986 two milestone tests were conducted in Experimental Breeder Reactor-2 (EBR-II). The first test was a loss of flow without scram and the second was a loss of heat sink without scram. Both tests were initiated from 100% power and in both tests the reactor was shut down by natural processes, principally thermal expansion, without automatic scram, operator intervention or the help of special in-core devices. The temperature transients during the tests were mild, as predicted, and there was no damage to the core or reactor plant structures. In a general sense, therefore, the tests plus supporting analysis demonstrated the feasibility of inherent passive shutdown for undercooling accidents in metal-fueled LMRs. The results provide a technical basis for future experiments in EBR-II to demonstrate inherent safety for overpower accidents and provide data for validation of computer codes used for design and safety analysis of inherently safe reactor plants.

Book Synopsis EBR-II Inherent Shutdown and Heat Removal Tests by :
Download or read book EBR-II Inherent Shutdown and Heat Removal Tests written by and published by . This book was released on 1985 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of inherently safe characteristics of LMFBR systems is being conducted in EBR-II. Experiments have been conducted which show (1) capabilities of heat removal without the aid of active safety systems and (2) capabilities to mitigate a reduction in-core cooling flow or heat rejection to the balance of plant (BOP) without aid of active control or protection systems. Experiments involving loss of forced reactor cooling flow and loss of all heat rejection to the BOP are planned to be conducted. Purpose of this paper is to summarize the result of the test program by presenting representative test data.

Available in PDF, EPUB and Kindle. Book excerpt: The Experimental Breeder Reactor II (EBR-II) is a liquid metal reactor (LMR) whose sodium-bonded metallic fuel core has substantial negative reactivity feedback. It has been demonstrated that this feedback enables a loss-of-flow without scram (LOFWS) to shut the reactor down without operator action. This inherent effect also causes a reactor shutdown following a loss-of-heat-sink without scram (LOHSWS). On April 3, 1986, an LOFWS and an LOHSWS were each performed from full power. In the latter test the secondary sodium flow was reduced to less than 1% about three minutes. This caused the reactor inlet temperature to increase only about 45°C and essentially stopped the fission process and shut the reactor down. These tests demonstrated that an LMR plant can be designed in which natural phenomena, rather than electromechanical systems (such as those which move control rods), are effective in protecting the reactor against the potentially adverse consequences of loss-of-primary-flow and loss-of-heat-sink accidents. Moreover, the same phenomena which shut the reactor down during these two tests could be exploited to allow primary flow or inlet temperature, rather than control rods, to be used to maneuver plant output within a considerable power range. This capability would enable an LMR to be designed in which far less reactivity is invested in the control rods than is currently the practice. The ultimate goal is to design an ''inherently safe'' LMR in which reactor safety does not depend upon control rods and also where severe rod withdrawal accidents do not need to be considered.

Download or read book Data Handling at EBR-II (Experimental Breeder Reactor II) for Advanced Diagnostics and Control Work written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Improved control and diagnostics systems are being developed for nuclear and other applications. The Experimental Breeder Reactor II (EBR-II) Division of Argonne National Laboratory has embarked on a project to upgrade the EBR-II control and data handling systems. The nature of the work at EBR-II requires that reactor plant data be readily available for experimenters, and that the plant control systems be flexible to accommodate testing and development needs. In addition, operational concerns require that improved operator interfaces and computerized diagnostics be included in the reactor plant control system. The EBR-II systems have been upgraded to incorporate new data handling computers, new digital plant process controllers, and new displays and diagnostics are being developed and tested for permanent use. In addition, improved engineering surveillance will be possible with the new systems.
Book Synopsis Operational-safety Advantages of LMFBR's by :

Book excerpt: LMFBR's contain many inherent characteristics that simplify control and improve operating safety and reliability. The EBR-II design is such that good advantage was taken of these characteristics, resulting in a vary favorable operating history and allowing for a program of off-normal testing to further demonstrate the safe response of LMFBR's to upsets. The experience already gained, and that expected from the future testing program, will contribute to further development of design and safety criteria for LMFBR's. Inherently safe characteristics are emphasized and include natural convective flow for decay heat removal, minimal need for emergency power and a large negative reactivity feedback coefficient. These characteristics at EBR-II allow for ready application of computer diagnosis and control to demonstrate their effectiveness in response to simulated plant accidents. This latter testing objective is an important part in improvements in the man-machine interface. (MMI).

Book excerpt: Two tests of great importance to the design of future commercial nuclear power plants were carried out in the Experimental Breeder Reactor-II on April 3, 1986. These tests, (viewed by about 60 visitors, including 13 foreign LMR specialists) were a loss of flow without scram and a loss of heat sink without scram, both from 100% initial power. In these tests, inherent feedback shut the reactor down without damage to the fuel or other reactor components. This resulted primarily from advantageous characteristics of the metal driver fuel used in EBR-II. Work is currently underway at EBR-II to develop a control strategy that promotes inherent safety characteristics, including survivability of transient overpower accidents. In parallel, work is underway at EBR-II on the development of state-of-the-art plant diagnostic techniques.
