| dc.description.abstract | A numerical comparison of international light water reactor
operating performance from 1975 to 1984 was carried out in
an attempt to identify trends and discrepancies in PWR and
BWR performance.
The countries examined were: France, the Federal Republic
of Germany, Japan, Sweden, Switzerland, and the United
States. Reactor performance losses for each country were
broken down into many categories for examination and
comparison including: Fuel, Reactor Coolant System, Steam
Generators, Refueling, Turbines, Generators, Condensers,
Circulatory/Service/Component Cooling Water Systems,
Economic, Husan, Regulatory, and Unknown. Additionally,
losses were also distinguished as forced or scheduled. All
loss categories were plotted as functions of both time and
reactor age.
It was found that from 1975 to 1984 the Swiss PWR and BWR
performance was the highest averaging 85.8X and 88.0X
respectively. The lowest PWR performance was in Sweden
averaging 54.4X. Germany was found to have the lowest BWR
performance averaging 51.1X.
For the PWR's, differences in regulatory, steam generator,
and economic losses were found to be the common contributors
to low performance. For BWR's, differences in regulatory,
reactor coolant system, and fuel losses were found to be
the common contributors to low performance.
Time and age dependent trends were observed for losses in
many of the loss categories. | en |
