claimThe International Atomic Energy Agency (IAEA) states that steady, near full capacity, baseload operation of nuclear power plants is often considered the most efficient use of capital investment for several reasons: constant thermal/electrical power operation is easier with fewer changes in plant condition; high capital costs combined with relatively low variable fuel costs make full-load operation the most cost-effective; baseload operation allows for more efficient utilization of nuclear fuel; and design and licensing are simpler for constant load operation because plant degradation and safety margins are more predictable.
claimA nuclear power plant may contain multiple generating units, with each reactor serving as the main element of a single generating unit.
claimWhile nuclear power plants do not directly emit greenhouse gases, they generate emissions through support systems and ancillary activities, including emergency diesel generators, onsite motor vehicles, and offsite power usage during refueling or maintenance.
