Several tools are available or being developed that
can be used to quantify nuclear data uncertainties
and sensitivities
UQ/S studies can inform nuclear data priorities
Covariance data are lacking and sometimes not
well quantified
Nuclear data end-use uncertainties must be
defined

Even if good quality data are available in
ENDF, there are cases where the evaluation
codes, data processing codes, or transport

The actinide “network” contains many short-lived
actinides that are difficult to measure
Solution requires decay data, theoretical models and
experiments
Measure well the long-lived isotopes to bound the
solution of the short-lived isotopes

NDREW Session Summary
 
Breakout Session Goals
Determine
 mission-driven 
nuclear data priorities with targeted uncertainties
Obtain user input
Determine all 
tasks
 required to ensure that nuclear data are available to users:
Measurements – differential and integral
Evaluations
Processing
Covariance data
Validation
Testing
Create a mechanism for 
peer reviewed 
ideas
Determine where needs 
overlap
 with other mission spaces
Capture opportunities to 
leverage
 or enhance existing funded/planned work
Think outside the confines of the typical funding mechanisms
What does it really take to get it done right?
 
NDREW Feedback
General Comments:
Collaboration opportunities
Obtained a broad view of the problems/increased awareness
Helped in understanding the needs of the different applications
Useful information was exchanged/discussion format helpful
Necessary process in addressing NA-22’s nuclear data needs
Should be annual event 
Breakout Sessions:
Some of the facilitators did not engage
Facilitators inconsistent
Breakout needed to be more cozy and interactive
Agency/User input
Needs to be more application oriented
Need more detailed agency overviews/need more direction
More agency input in each breakout session
Need more user input
Thursday Afternoon Review:
Helpful for missed sessions/ too top level and general
 
Moving Forward
Annual NDIWG FOA is anticipated
Annual Workshop will provide input for the FOA
Challenges:
Prioritizing nuclear data needs when many are deemed necessary
Deconflicting between programs and international efforts
Staying 
mission-centric
; ensuring that recommended work is relevant and
necessary
Avoiding entropy by demonstrating 
mission impact
 
Workshop for Applied Nuclear Data Activities
January 22 – 24, 2019
George Washington University, Wash, DC
Classified day 25
th 
(invite only)
Program focus on:
Nuclear Energy
Isotope Production
Safeguards
Same format as NDREW – facilitated discussions
2 parallel sessions
Review of NDIWG FOA funded projects
Program updates by program managers
Wrap up on Thursday afternoon
 
WANDA will be held at George Washington University
Friday session at Forestall
Two additional rooms available for breakout sessions
 
Wanda Skeleton Agenda
 
What WANDA offers
A venue to encourage communication between consumers and
providers of nuclear data
A place to hear from PMs about their vision for their programs
A place to form new collaborations that ensure that data needs are
addressed in an end-to-end fashion
The goal is a roadmap/plan for multiple sponsors to
address nuclear data needs
Identified
Need

Nuclear Data Topic Selection
General Focus:  Nuclear Energy, Isotope production, Safeguards related
Nonproliferation topics not covered fully last year
Eight ½ day sessions available
SELECTION CRITERIA
MISSION IMPACT:  Does anyone care?   Should anyone care?
SPONSOR INTEREST:  Is there a potential sponsor?  Does the sponsor care?
 
Safeguards topic area suggestion
Safeguards measurements are used to ensure that nuclear material  declarations
are accurate; and that no significant quantities of nuclear material have been
diverted for misuse or weaponization. These measurements are very dependent
on the quality of the 
atomic and nuclear data 
used in the physics-based models
and codes that analyze the 
gamma, neutron, and heat signatures 
collected.  Poor
knowledge of the underlying nuclear data, reduces the ability of a Safeguards
inspector to fully quantify the uncertainties associated with safeguards
measurements.
INMM -July 2019:
Suggested a Nuclear Data 101 “workshop” is planned during the NDA experts meeting on
Sunday.
A nuclear data session during the regular meeting is planned

Recent events in nuclear data include workshops, whitepaper releases, interagency working group meetings, and roadmapping workshops aimed at enhancing nuclear data for various applications. DOE Nuclear Physics has organized interagency working group FOAs to improve nuclear data through collaborative projects. The Nuclear Data Roadmapping and Enhancement Workshop brought together participants from various institutions and government agencies to discuss nuclear data needs and capabilities.
