The steam generator changeout at Beznau-1
At the Beznau-1 nuclear power plant in Switzerland, the unit's two steam generators were replaced in the second quarter of 1993. The steam generator replacement portion of the outage - the period from when contractors were given access to the containment to when the steam generators were ready for hydrostatic pressure testing - was 44 days (April 12- May 26, 1993), shorter than the 46 days gained. Total length of the outage was 99 days (April 2 - July 9). Collective radiation dose received by project personnel was 110 person-rem, much less than the planned 250 person-rem. Project cost was about $50 million, including the new SGs and the replacement work, according to Nordostschweizerische Kraftwerke AG (NOK), plant owner and operator.
