PROCEDURES IN EMERGENCIES INVOLVING UTILITY AND FEED LOSSES Unusual or unexpected operating problems in the Per-Tri Plant have developed in the past, and, of course, will occur.in the future. Each emergency situation such as a loss of one of the utilities or reactor feeds allows us a better knowledge of operations through experience. To summarize some of the previous problems, and consider other possible emergencies, this report is being compiled. Prior thought to loss of feeds or utilities, or other adverse conditions may avoids major damages or a disaster within the plant. Additions and corrections to the following discussions by any of the Per-Tri personnel are encouraged. This information should be kept up to date and should be especially beneficial for personnel newly assigned to the Per-Tri Plant. Abstract Conditions and operating procedures are discussed in this report for the following utility and feed losses: 1. Loss of 0a 2. Loss of Na 3. Loss of both 0a and Na 4. Loss of instrument air 5.
