Abstract This paper describes ASEA-ATOMS activities in the noise field, and presents some practical experience on how results from process noise analyses may be interpreted. Process noise has been studied in all the operating ASEA-ATOM BWRs, chiefly during reactor commissioning, but also after commencement of commercial operation. During commissioning, process noise is studied in various modes

Totalt byggdes 11 kärnkraftreaktorer av ASEA-ATOM:s konstruktion. Av dessa finns 9 i Sverige (Barsebäck, Oskarshamn, Ringhals och Forsmark) och 2 i Finland (i Olkiluoto nära Rauma). Dessutom har det byggts tre tryckvattenreaktorer (PWR) av Westinghouse-konstruktion. Alla dessa reaktorer är fortfarande i drift utom de två During 1974 ASEA-ATOM, an overseas manufacturer of BWR's, advised GE that preliminary % formation from tests with single spray nozzles in pressurized steam environments indicated that the nozzle spray patterns were affected by several test parameters, including the steam pressure and nozzle flow rate. More specifically, the characteristic cone Ringhals 1 was built by Asea atom between 1969 and 1975. In 1976 it was put into operation and has delivered 220 terawatt hours of electricity to the Swedish electricity grid. Ringhals 1, a 910MWe boiling water reactor (BWR) was built by Asea Atom between 1969 and 1975 and began operation in 1976.

In some respects the nuclear and hydraulic design of the ASEA- ATOM BWR differs from that adopted by other BWR manufacturers. ASEA-ATOM SUMMARY BWR 75 designates the most recent design of the ASEA-ATOM boiling water reactor on which the basic design was carried out during 1974 and 1975. The first plants of this new de-sign were ordered by Swedish customers in 1975 and 1976.

Land for the plant was bought in 1965 by the energy company Sydkraft, and the first of the two BWR reactors was ordered from Asea-Atom in 1969. Unit one first attained criticality on January 18, 1975 and commercial operation began on May 15.

The new standard ASEA- ATOM BWR features a number of such refinements and design improvements involving main circulation punips, containment design, refuelling system and off-gas treatment plant.
