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.
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

Helping to save the plant safety puzzle: An overview of PRA
Probabilistic risk assessments (PRAs) have advanced the safe operation of the U.S. reactor fleet over many decades. Risk insights from PRAs have provided information from many different perspectives, from what is most important to maintain at a facility to a better understanding of how to address new information regarding safety issues. The methods and tools that have supported the creation and enhancement of PRA models were established through multiple decades of research, starting with WASH-1400, The Reactor Safety Study,1 published in 1975, through the comprehensive plant-specific models in use today.

Presented at the
MCD Topical Meeting Banquet
The Gerald C. Pomraning Memorial Award recognizes individuals who have made outstanding contributions toward the advancement of the fields of mathematics and computation in support of advancing the understanding of these topics of interest to the ANS membership.
When possible, one such award will be made every other year, coinciding with the year the Mathematics and Computation Division (MCD) Topical Meeting is held, following procedures established by the MCD.
Nominees need not be ANS members, and any ANS member can nominate a worthy candidate.
The award consists of an engraved plaque and monetary award of $1,000 which is presented at the MCD Topical Meeting, held in the spring of odd-numbered years, in addition to complementary registration at the MCD meeting.
The award was established by the Mathematics and Computation Division in 2002 as a Division-Administered award. It is named after Dr. Gerald C. Pomraning, who contributed greatly to the advancement of the fields of mathematics and computation in support of advancing the understanding of topics of interest to the ANS membership. This award is made possible by a $15,000 contribution from SAIC, a company that Dr. Pomraning co-founded.
Nominations must include the completed nomination form accompanied by the following supporting documents:
The principal sponsor has the responsibility of (a) securing the required letters of recommendations from the other two co-sponsors, (b) assembling the nomination package, and (c) submitting it to ANS along with his or her own recommendation of the nominee by the deadline indicated in the call for nominations announcement.
Evidence of the candidate’s contribution shall be submitted in the form of written recommendations from the sponsors and others as appropriate. Written recommendations should specify the candidate’s outstanding accomplishments and contributions that have benefited the fields of mathematics and/or computation in support of advancing the understanding of topics of interest to the ANS, to the degree meriting consideration for the Gerald C. Pomraning Memorial Award.
The selection of the Gerald C. Pomraning Memorial Award recipient is determined by critical review and assessment of submitted credentials and qualifications; hence, due care should be exercised in preparation of the nomination package. In the process of review and selection, emphasis is placed on excellence of achievement in the fields of mathematics and/or computation in support of advancing understanding of topics of interest to the ANS membership as evidenced by (a) outstanding original research, documented in refereed scientific journals or major publications and by (b) outstanding technical leadership.
Consideration for the Gerald C. Pomraning Memorial Award requires a willingness and formal acceptance on the part of the candidate to attend the MCD Topical Meeting at which the award will be presented at, unless unusual circumstances prevent attendance. Members of the MCD Executive Committee and Honors and Awards Committee are excluded as nominators of, as well as candidates for the award during their respective terms of office.
