DOE-HDBK-3010: Otherwise known as…
The Accident Analysis HandbookMishima’s HandbookDOE 3010The DOE Handbook DOE-HDBK-3010-94, “Airborne Release Fractions/Rates
and Respirable Fractions for Non-Reactor Nuclear Facilities”
3
Accident Analysis Method
Focus on co-located worker and public receptor Inhalation dose dominates the overall doseDetermine the amount of radioactive material driven
airborne to estimate downwind consequences for an accident
Airborne source term estimated by 5-factor formula
4
The 5-Factor Formula
Source Term = MAR x DR x LPF x ARF x RF
where:MAR = Material at risk (curies or grams)DR = Damage ratioLPF = Leak path factorARF = Airborne release fractionRF = Respirable fraction
5
The 5-Factor Formula
Source Term = MAR x DR x LPF x ARF x RF
where:MAR = Material at risk (curies or grams)DR = Damage ratio set to 1.0LPF = Leak path factor set to 1.0ARF = Airborne release fractionRF = Respirable fraction
6
The 5-Factor Formula
Source Term = MAR x ARF x RF
where:MAR = Material at risk (curies or grams)ARF = Airborne release fractionRF = Respirable fraction

Baking Powder Demonstration
The cup of baking powder represents an amount of material at risk (MAR)
Accident: Drop or spill of powderThe visible cloud is a good indication of the aerosol
released from the accident (ARF)The very small particles more closely represent the
respirable fraction (RF)How much respirable aerosol was produced?

Creation of the DOE-HDBK-3010
During 1980’s DOE began to increasingly emphasize ES&H issues
DOE sponsored the Defense Programs Safety Survey in 1993
One objective of survey was to “Develop consistent data and methodologies for making conservative estimates of basic consequence derivation parameters”
The research and compilation of data was documented in DOE-HDBK-3010 (two volumes)
9
Goals of DOE-HDBK-3010
Systematically compile airborne release and respirable fraction experimental data for non-reactor nuclear facilities
Assess available dataProvide values derived from data assessment that may
be used in accident analysis

Limitations of DOE-HDBK-3010
Best estimates by experts using data available at the time
Provides a general basis for decision makingLimited range of some valuesMedian and average values included only for perspective
on potential conservatismNot meant to be used for “pencil sharpening” of ARF/RF
to meet safety basis
19
Use of DOE-HDBK-3010 at WTP Provides basis for many of the ARF x RF values used in
PDSA However, 3010 is not directly applicable in all accident
scenarios (e.g. non-Newtonian waste) Several DNFSB questions have driven additional testing
applicable to WTP waste:i. Spray leaks
ii. Sparger entrainment
20
Conclusions
DOE-HDBK-3010 is a good starting point for any accident analysis
3010 is an excellent source of DOE recognized methodology and ARF/RF values
