El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

Award
Engraved Bronze Medal
The Walter H. Zinn Medal recognizes an individual for outstanding contributions to the advancement or implementation of nuclear technology. This award is to recognize notable and sustained technical contribution, leadership, or other service that has not been widely recognized.
Nominees may be from any nation, but they must not be deceased at the time the awardee is selected and need not be ANS members.
The award consists of an engraved medal. It is to be made no more frequently than once per year and is normally conferred during the ANS Annual Conference.
This award was established by the Operations & Power Division in 1976 with the inaugural award going to Walter H. Zinn, a pioneer in nuclear reactor development and the Society's first President, for his many contributions to the development of nuclear power. Subsequent recipients have been selected by the Operations & Power Division Honors and Awards Committee to recognize individuals who have made outstanding contributions to nuclear power. In August 2018, the OPD and ANS H&A Committee elevated this award to a national Top Tier ANS award, and it was renamed the Walter H. Zinn Medal.
Nominations must include the completed nomination form accompanied by the following supporting documents:
