Award
$2,500* and a Bronze Medallion
The Untermeyer & Cisler Reactor Technology Medal recognizes an individual(s) who have made outstanding scientific, engineering, or management contributions to the advancement of nuclear reactor technology. The contributions may involve technology development, reactor system design, safety, deployment, or operation. The award scope considers any fission-based reactor technology.
The award consists of an engraved medal and a monetary award of $2500*. The award is to be made twice per year, normally conferred during the ANS Annual or Winter Conference.
Nominees may be from any nation, must be living at the time the awardee is selected, and do not need to be ANS members.
*In lieu of a cash award, recipients can opt for travel reimbursement up to the award amount.
This award is a combination of the earlier independent Untermyer, Cisler, and Reactor Technology awards. The three awards were combined in 2023 by the ANS Honors & Awards Committee.
Nominations must include the completed nomination form accompanied by the following supporting documents:
The selection committee consists of seven (7) members – six (6) from the Honors and Awards Committee and one (1) from Atomic Energy Society of Japan, appointed by AESJ. They review the nominations and make their recommendation to the chair of the Honors and Awards Committee. If the committee determines that there is no candidate of sufficient merit, the committee may recommend that the award not be made in that year.
