PISCES (Plant Instrumentation Surveillance, Calibration and Evaluation System): A computerized instrument calibration recall system

The Plant Instrumentation Surveillance, Calibration and Evaluation System (PISCES) tracks calibration and functional testing. We introduced it in 1983 at Hanford's 200 East and 200 West Areas. The first affected facility was Plutonium and Uranium Extraction (PUREX). Other facilities followed until the last major facility was added in July of 1988. Initial system structure was a mainframe computer database with remote access from an IBM PC via telephone modem. Program language was Fortran. Acquisition of a Micro Computer Fileserver and small local area network in 1984/85 enabled 200 Area Maintenance Engineering to enhance update and report capabilities by reprogramming in dBASE II. We are continuing to add upgrades to PISCES to provide a better multi-user environment. The language of choice is Advanced Revelation. This database management system was selected and is being used by Boeing Computer Services, Richland to develop the Site Wide Job Control System.
