Pages Extracted from F Division Monthly Progress Reports March 1945 to November 1945
This provides a compilation of Bretscher’s Group F-3 monthly progress reports in 1945. They are of historical importance because they cover the period when Los Alamos measured the DT cross section and discovered the large resonance enhancement, at DT energies relevant to thermonuclear application. See the July 1945 report in particular. Prior to this, the DT cross section was first measured at Purdue in 1943, but at much higher energies that are less relevant for applications. Numerical values are not given here – they can be found in the 1946 report LA-582 and Phys. Rev. 75, 1154 (1949).

A Look At Topics and Topic Clusters for DOE Laboratories, 1996 - 2021 [Slides]
Beginning in 2018, Elsevier through its Scopus database introduced topics to further refine its classification of publications: Previous classification schemes used concepts such as subject areas, e.g., physics and astronomy, chemistry, computer science, etc.; Topics, in contrast, are much more granular. There are over 96,000 and their titles/contents are very specific, e.g., “Multilayers; Interfaces (materials); Individual layer." Elsevier topic clusters or Clarivate citation topics represent good approaches to examining an institution’s scientific productivity areas. These approaches have the granularity that is not present in the previous categorization approaches used by these databases. The Elsevier topic clusters for the DOE Laboratories do not appear to vary that much over the 1996 – 2021 period. In some cases (ANL, LBNL, LANL, ORNL, and PNNL), there were over 1000 topic clusters at these Laboratories, but a consistent set formed the core of the publication activity. Diversity is viewed as a desirable property of a research portfolio. Examining the balance component of the DOE laboratories, the spread is uneven or not diverse. This may be due to the missions of these laboratories. The balance of a single university was unequal too.

American Nuclear Society 2023 Student Conference [Slides]
This presentation is titled American Nuclear Society 2023 Student Conference and is led by with introductions from a few of the students. This presentation touches on how operations serve the mission, and everyone is a part of it. In order for anyone to operate with special nuclear material (SNM) the responsible contractor or licensee must comply with several regulations. The presentation touches on how there are several roles involved in operations. This talk also includes a page of references, regulations, standards and guidance. The presentation concludes with a section on Material Balance Areas (MBA).

Writing Competitive Proposals [Slides]
A proposal is a written response to an opportunity offered by a funding organization. Proposals must meet a SOLICITOR’S needs, not YOUR needs. A solicited proposal is a written response to a specific solicitation issued by a sponsor. These solicitations are typically called RFPs, or Requests for Proposals. RFPs are specific in their requirements regarding format and technical content. Scientists at Los Alamos often deal with this type of proposal — Laboratory-Directed Research and Development (LDRD) proposals are one example. An unsolicited proposal is one submitted to a sponsor who has not issued a specific solicitation. It usually comes about during interactions at meetings or conferences. In some instances, a sponsor may be visiting for another reason when the possibility for an unsolicited proposal becomes available. A pre-proposal is one in which a sponsor wishes to gage competition before having participants prepare a formal, full-length proposal. These types of scenarios imply that the actual proposal could be highly competitive and will usually be by invitation only.

Development and Porting of Nuclear Reactor Computational Models for the NRIC Virtual Test Bed in FY23
The U.S. DOE’s National Reactor Innovation Center (NRIC) hosts an open-source website and associated GitHub repository called the Virtual Test Bed (VTB) on which computational models for advanced reactors are documented and shared with the reactor community. In FY23 under the NRIC program, computational models for nuclear reactor analysis were developed and contributed to the VTB Github repository during FY23 by contributors at Argonne National Laboratory. Other models developed outside of NRIC were also ported to the VTB as part of this work, serving a broader mission to make computational reactor analysis models more widely available to the reactor community. The model development activities focused on demonstration of gas-cooled microreactor models including computational fluid dynamics simulations of flow through an industry-inspired air jacket design, and simulation of multiphysics transients for a gas-cooled microreactor assembly. Additionally, development of a molten salt reactor (led at Idaho National Laboratory) was supported through Argonne’s expertise in multigroup cross sections generation. Models for these two reactor types were targeted due to their relevancy to NRIC’s Demonstration of Microreactor Experiments (DOME) and Laboratory for Operation and Testing in the U.S. (LOTUS) physical test beds, which are slated to host microreactor and molten salt reactor experiments. The model porting activities consisted of developing detailed documentation for several physics models which originate from the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program. We include only contributions from Argonne National Laboratory in this report.
