2021 Nuclear Data for Reactor Antineutrino Measurements Workshop

21 Jun 2021, 11:00 → 24 Jun 2021, 17:00 US/Eastern

ONLINE

WoNDRAM is a “mini” workshop organized by the Nuclear Data Working Group (https://www.nndc.bnl.gov/ndwg/) to address the impact of nuclear data on reactor antineutrino measurements.

The goals of the workshop are:

1. Identify nuclear data needs for the reactor source term, the antineutrino spectrum calculation and the detector response that impact the fundamental research and applications of reactor antineutrino measurement systems.
2. Recommend solutions to the identified nuclear data needs.
3. Bring together the various communities involved in reactor antineutrino measurements along with the nuclear data community to enhance communication and understanding.

The workshop consists of a plenary and three topical discussion sessions:

1. Nuclear Data for Reactor Source Term Calculations
2. Nuclear Data for Antineutrino Spectrum Calculations
3. Nuclear Data for Detector Response Calculations

The objective of each session is to obtain community consensus of nuclear data needs and recommended solutions.

Nuclear Data for the Reactor Antineutrino Source Term

Session Chairs
- Andrew Conant
- Catherine Riddle
- William Wieselquist

The goal of the Reactor Antineutrino Source Term session is to focus nuclear data needs for nuclear reactor modeling & simulation, operation, and applications that directly impact the simulated reactor antineutrino source term. The session covers nuclear data uncertainties through the fission process and other in-reactor nuclear reactions. Additionally, the impact of uncertainties in reactor operations will be addressed. Examples of topics to be covered include: fission yields, non-fuel effects, advanced reactors and spent fuel storage. Nuclear data needs will be identified along with proposed solutions and recommended improvements in modeling & simulation capabilities to support reactor antineutrino measurements.

Nuclear Data for Antineutrino Spectrum Calculations Session

Session Chairs:
- Bryce Littlejohn
- Pat Huber
- Shikha Prasad
- Alejandro Sonzogni

Antineutrinos produced by nuclear reactors are potentially useful for non-proliferation and reactor monitoring applications, for validating other existing and future datasets in the nuclear data pipeline, and for performing fundamental particle physics measurements. These three spheres of application rely to varying degrees on an accurate and precise understanding of the true aggregate antineutrino energy spectrum emitted by each primary fission isotope. The goals of this session are to identify future experimental, theory and software improvements that can expand understanding of directly-measured and indirectly-predicted antineutrino spectra, and to define the extent to which each of these improvements will benefit the three spheres of application described above.

Nuclear Data for the Antineutrino Detector Response Session

Session Chairs
- Bethany Goldblum
- Nathaniel Bowden
- Jon Link
- Pieter Mumm

Advances in detector modeling capabilities would further the development of basic and applied antineutrino physics technologies. This session focuses on identifying and prioritizing nuclear data needs that impact the ability to model antineutrino detector performance in the reactor energy range—important for detector design, development, and data interpretation. This includes data deficiencies for modeling both neutrino signal and background for a wide range of detection techniques such as CEvNS, electron elastic scattering, and inverse beta decay.
