Book Description
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 Description
The experimental evaluation was conducted on two typical wing splice joint configurations used in the C5-A aircraft consisting of two aluminum layers each 3/16 to 1/4 inches thick. Notches simulating cracks were machined in a radial direction extending from the fastener hole and the faying surface between sheets. A digital eddy-current system designed around a PDP-11/40 minicomputer was utilized for the experimental evaluations. The digital system was programmed to generate the signal wave-forms that excite the test coil and perform the function of phase-sensitive detection of response signals that are received from the test coil. Special test coils were designed to induce eddy currents in the aluminum alloy that lies beneath the head of the fasteners. A series of measurements were taken on the wing-splice samples at various frequencies, excitation levels, and phase settings. These data were analyzed using the Automatic Interaction Detector, AID, computer code to indicate initial capabilities of crack detection, and to compare the various operating parameters such as excitation frequency and test coil design.
