There are 6 ways to develop nuclear plants and parts FASTER, CHEAPER, and with GREATER RELIABILITY.
Renewable plants are considered intermittent or variable sources and are mostly limited by a lack of fuel (i.e. wind, sun, or water). As a result, these plants need a backup power source such as large-scale storage (not currently available at grid-scale)—or they can be paired with a reliable baseload power like nuclear energy.
