A simplified procedure is proposed, which reduces the cost of steam turbine acceptance testing without significantly affecting testing accuracy. This simplified acceptance test procedure is applicable to both fossil and nuclear power plants. It involves only the measurements required to calculate heat rate and required to compare the test value to guarantee. The object is to simplify the acceptance test and to reduce its cost to the extent that a no-tolerance acceptance test is conducted on every new, large steam turine-generator unit. While maintaining the traditional high level of testing accuracy, this method also facilitates periodic testing. The results of such tests can provide the information required for scheduling plant outages for maintenance or repair thus ensuring efficient operation of the steam turbine/feedwater cycle throughout the life of the turbine.
