ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Ian Wall—ANS member since 1964
Ian Wall early in his career . . .
I graduated with a degree in mechanical engineering from Imperial College, London, in 1958. Nuclear power was viewed favorably at the time, so I took a 1-year course on the subject. I was then offered fellowships at Cambridge University and the Massachusetts Institute of Technology and thought the latter would be more interesting, so I moved to Cambridge, Mass., to study nuclear engineering. After completing my doctorate in 1964, I joined the American Nuclear Society and took a job with General Electric, then in San Jose, Calif.
In 1967, GE assigned me to explore the use of probability in reactor safety. At that time, the prevailing opinion was that the probability of a severe accident was infinitesimally small and the consequences would be catastrophic.

Monetary Award
$1,000
The Theos J. (Tommy) Thompson Award to recognize outstanding lifetime contributions to the field of nuclear reactor safety.
Nominees need not be ANS members.
The award consists of a plaque and a $1,000 monetary award which is presented by the chair of NISD during the ANS Winter Conference each year.
This award was established by the Nuclear Installations Safety Division (formerly the Nuclear Reactor Safety Division) in 1980 as a memorial award to the late Professor Theos J. (Tommy) Thompson of MIT, who made outstanding contributions to nuclear reactor safety, including being the principal author of a pioneering textbook on the subject. This award is funded by the operating budget of NISD.
The NISD Honors and Awards Committee administers this award. That committee establishes the evaluation criteria, solicits the nominations, and determines the recipient. The award is made to individuals selected by the NISD Honors and Awards Committee in recognition of outstanding contributions in the field of nuclear reactor safety. The ANS Honors and Awards Committee is available for consultation and review as appropriate.
Nominations must include the completed nomination form accompanied by the following supporting documents:
Nomination forms and supporting documents (in Word or Adobe Acrobat) should be emailed to honors@ans.org.
