Changing perceptions of the risks and benefits of nuclear power leads to increasing public support for nuclear > allows the NRC licensing process to be completely revamped and the culture of the organisation to be changed from «safety first» to an appropriate balance of all costs and risks, including the consequences of retarding nuclear development and rollout by making it too expensive to compete as well as it could if the costs were lower (e.g. higher fatalities per TWh if nuclear is not allowed to be cheaper than fossil fuels);
(Sec. 242) Requires the Secretary to establish a program to make monetary awards to encourage the owners and operators of new and existing electric energy generation facilities or thermal energy production facilities using fossil or nuclear fuel to use innovative means of recovering thermal energy that is a potentially useful byproduct of electric power generation or other processes to: (1) generate additional electric energy; or (2) make sales of thermal energy not used for electric generation, in the form of steam, hot water, chilled water, or desiccant regeneration, or for other commercially valid purposes.
Once hydrogen production is converted to a non-fossil source (probably electrolytic or thermochemical splitting of water, powered by nuclear energy) and all industrial hydrogen (for things like the Haber Process) sourced thus, it would probably be better to synthesize hydrocarbon fuels (either methanol, or Fischer - Tropsch petrol or diesel) than attempt to use hydrogen directly.
