Book excerpt: A number of different types of procedures are used in the operation of a nuclear power plant [1], including emergency operating procedures (eops) or abnormal incident manuals (aims), maintenance procedures, testing procedures, operating manuals (oms), field procedures, etc. oms are used for normal plant conditions or when minor incidents occur. in general, there is a separate om for each system in the plant [2]. instructions for performing manual tasks in the plant are contained in field and maintenance procedures. transients that could affect plant or public safety are known as abnormal incidents and require the use of eops. since the accident at three mile island, increased emphasis has been placed internationally on the development of eops to mitigate plant upsets. plants are becoming increasingly complex and require many volumes of procedure instructions to allow operation under all conditions. the amount of information has grown to the point where an automated means of referencing this knowledge would be beneficial. recent advances in technology have prompted research to develop computer tools to assist operations staff [3]. this report reviews recent developments in the field of computerized plant operating procedures in all aspects of the procedure lifecycle. in particular, the evolution of procedure resentation from paper-based manuals to computer systems is described and a classification scheme is proposed to categorize levels of procedure automation. the results of a literature survey are given to describe current work by institutions around the world, and the three prototype presentation systems developed by aecl research are outlined.

Book excerpt: Solubility measurements are reported for unirradiated uo2 fuel in molten zircaloy-4 cladding at temperatures of 2200, 2300 and 2400 degrees c. the alloy starting materials in these tests were 0-free zircaloy and a prefabricated zircaloy/25 at.percent 0 alloy, the latter being used to represent the 0-saturated zircaloy fraction of steam-oxidized cladding. the solubility results were obtained using methods similar to those previously employed for 2000-2200 degrees c solubility measurements. however, the earlier tests were performed using a uo2/zircaloy mass ration of approximately 10.9 to simulate the mass ratio in a 27 element candu fuel bundle. in the present tests, it was found necessary to perform the tests using a higher mass ration of approximately 20 to compensate for the progressive increase in uo2 solubility with rising temperature. at each test temperature (2200, 2300 or 2400 degrees c), the uo2 solubility in initially 0-free zircaloy was greater than in zircaloy/25 percent 0. these results corroborate the earlier conclusion tat fuel dissolution in previously unoxidized cladding represents a worst-case scenario during a severe fuel damage (sfd) accident. thus, prior steam oxidation of the cladding will mitigate the extent of fuel dissolution by two mechanisms, namely: a) conversion of the outer cladding surfaces to zr02, leaving less zircaloy available for dissolving fuel, and b) increasing the dissolved 0 content of the remaining zircaloy, thereby lowering its capacity for fuel dissolution. comparison of the 2200 degrees c/mr approximately 20 solubility results with the earlier 2200 degrees c/mr approximately 10.9 values also confirms that uo2 solubility is increased at lower uo2/zircaloy mass ratios. the implications for fuel dissolution modeling that arise from these results are discussed.

Book Synopsis Flow-induced Vibration of Power and Process Plant Components by : M. K. Au-Yang
Download or read book Flow-induced Vibration of Power and Process Plant Components written by M. K. Au-Yang and published by American Society of Mechanical Engineers. This book was released on 2001 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information on the most common flow-induced vibration problems in power and process plant components. Based on the author's own experience that most errors in engineering analysis come from confusions in the units, the author begins with a short chapter on units and dimensions. He then provides step-by-step examples in dual US and SI units, leading to the final objective of design analysis, problem solving, diagnosis and trouble shooting.

Book excerpt: Electrical and mechanical transients were used to simulate acoustic emission (ae) signals expected during a crack-growth experiment by temperature-pressure cycling of a pressure tube. electric noise simulated heater noise, while mechanical transients from pencil-lead breaks and ballpoint-pen impacts on a pressure tube, respectively simulated ae from crack growth and mechanical noise in an operating fuel channel. simulations were used, before cycling, to assess the method's capability to discriminate against noise, calibrate instruments for sensitivity, and interpret ae events observed during cycling. digital signal processing (dsp) techniques, using correlation and frequency analyses, were applied to digitized transients. results show that: (i) a spatial filter on the ae instrument provides about 60 db discrimination against extraneous electrical and mechanical noise, (ii) ae bursts from ballpoint-pen impacts and pencil-lead breaks, on a pressure tube, contain low (

Book excerpt: OAK-B135 Flow-induced vibration in heat exchangers has been a major cause of concern in the nuclear industry for several decades. Many incidents of failure of heat exchangers due to apparent flow-induced vibration have been reported through the USNRC incident reporting system. Almost all heat exchangers have to deal with this problem during their operation. The phenomenon has been studied since the 1970s and the database of experimental studies on flow-induced vibration is constantly updated with new findings and improved design criteria for heat exchangers. In the nuclear industry, steam generators are often affected by this problem. However, flow-induced vibration is not limited to nuclear power plants, but to any type of heat exchanger used in many industrial applications such as chemical processing, refrigeration and air conditioning. Specifically, shell and tube type heat exchangers experience flow-induced vibration due to the high velocity flow over the tube banks. Flow-induced vibration in these heat exchangers leads to equipment breakdown and hence expensive repair and process shutdown. The goal of this research is to provide accurate measurements that can help modelers to validate their models using the measured experimental parameters and thereby develop better design criteria for avoiding fluid-elastic instability in heat exchangers. The research is divided between two primary experimental efforts, the first conducted using water alone (single phase) and the second using a mixture of air or steam and water as the working fluid (two phase). The outline of this report is as follows: After the introduction to fluid-elastic instability, the experimental apparatus constructed to conduct the experiments is described in Chapter 2 along with the measurement procedures. Chapter 3 presents results obtained on the tube array and the flow loop, as well as techniques used in data processing. The project performance is described and evaluated in Chapter 4 followed by a discussion of publications and presentations relevant to the project in Chapter 5, while the conclusions and recommendations for future work are presented in Chapter 6.
