So-called small modular reactors (SMRs) are defined as nuclear reactors which generate 300 Mega Watt equivalent or less energy. In short, this is a small-scale nuclear plant. It costs a lot less ( a traditional nuclear plant costs $6-9 billion. SMRs can save 15% to 40% to build.)

Critics of nuclear power claim SMRs suffer from many of the same problems as large reactors, most notably safety issues and the unresolved problem of what to do with long-lived radioactive waste. Further, SMRs will require substantial government subsidies to build and run. It is clear that the traditional nuclear industry needs SMRs, according to M.V. Ramana, a leading scholar at the Univ. of British Columbia.

While Biden supports renewable energy sources, he will continue Trump's policy, supporting US nuclear energy exports. Also, consider that nuclear energy now only supplies 11 percent of electricity (vs. 17.6% in 1996). Also, consider the cost of energy prices: coal prices $.06/kWh; fossil prices $.05/kWh; solar prices $.03/kWh; nuclear prices $.0077/kWh.

Considering the costs, benefits, and risks aspects of both SMRs and renewable energy, should the US focus on investing in nuclear power (including SMRs), or should we focus on sustainable, renewable energy sources? Support your argument.
