Title: Analyzing a Release of the Secret Herbs and Spices
1Analyzing a Release of the Secret Herbs and Spices
- Protecting the flock without giving up the recipe
- Charles Rives
- BW Pantex
- Pantex Plant Emergency Hazards Analyst
Consequence Assessment Team Leader
2Summary
- An approach to developing a reasonable and
conservative source term that allows an Emergency
Planning Hazards Assessment (EPHA) to provide
emergency decision-makers with information that
they need to know during an emergency involving a
release of materials with classified material
quantities or identities. - All discussion will be unclassified.
- This presentation uses a fictitious example of a
scenario, material types and material quantities.
3Accuracy
- Accurate with regard to the most important
decisions . . . - When and where protective actions need to be
implemented - Emergency categorization and classification
- Deliberately inaccurate otherwise
- Honest about the inaccuracy
4Accuracy
- Each of these models is inaccurate in some way
but can provide different users what they need to
know.
5If
- Material-A has an PAC-2 value of
- 1 mg/m3 and
- We have 1 kg of it, then that one kg can fill a
volume of 1x106 m3 with a concentration equal to
PAC-2. - (1kg)(1000g/1kg)(1000mg/g)(1m3/1mg)1x106 m3
- Then, if material-B has a PAC-2 value of 2 mg/m3,
- We can multiply the volume at PAC-2 for
material-A by the PAC-2 number for material-B and
come up with source term-B or STB.
6The Conversion - Graphically
7Source Term B
- STB(1x106 m3)(2mg/m3)2x106mg or 2kg
- I could represent a release of 1 kg of material-A
with a 2 kg release of material-B. - Or, if I have a mix of material-A and material-B,
I could use this ratio and treat it all as either
material-A or all as material-B and never even
acknowledge that material-A was there - (at least until the day that it actually happens
when the rules can sort of change).
8Arithmetic
- Now, if I have a fictitious source term with 1 kg
of material-A AND 1 kg of material-B, I could
treat it like this - 1 kg of A 1 kg of A
- 1 kg of B 2 kg of A
- 1 kg of A 1 kg of B 3 kg of A
9Fictional Scenario Background
- We make the best fried chicken in the world
- The Sultan of Absurdistan wants our chicken
recipe for part of his global war on poultry - We have to keep the recipe from him
- If we have an accident in the kitchen and spill
the herbs and spices, we could endanger the flock
10Fictional Scenario CG
- /// ALL OF THIS INFORMATION IS FICTIONAL AND
UNCLASSIFIED /// - The fact that we have the secret recipe for fried
chicken (U) - The fact that theres more than one herb or spice
in the recipe (U) - The fact that we use cayenne in our recipe (OUO)
- The amount of cayenne in the recipe (S)
- The fact that we use Red Chili in our recipe (S)
- The quantities and ratios of spices in the recipe
(S) - CLASSIFICATION IS FOR EXAMPLE PURPOSES ONLY
11Recipe (S)
- /// ALL OF THIS INFORMATION IS FICTIONAL AND
UNCLASSIFIED (and probably not very tasty) /// - 1 Chicken (U)
- 1 kg Cayenne (S)
- 2 kg Red Chili (S)
- CLASSIFICATION IS FOR EXAMPLE PURPOSES ONLY
12Fictional Protective Action Criteria
No. PACs Based on 60-min. AEGLs, ERPGs, or TEELs PACs Based on 60-min. AEGLs, ERPGs, or TEELs PACs Based on 60-min. AEGLs, ERPGs, or TEELs Units Comments and Changes from PAC Rev XX
No. Chemical Name PAC 2 PAC 3 Units Comments and Changes from PAC Rev XX
F1 Chicken 200,000 400,000 mg/m3 Fictional
F2 Cayenne 10 30 mg/m3 Fictional
F3 Red Chilli 20 60 mg/m3 Fictional
13Converting all of the STs to their PAC Volume
Source Term A (kg) Material Fictional PAC-2 (mg/m3) PAC-2 Volume (m)
2 Chicken 20000 100
1 Cayenne 10 100000
2 Red Chili 20 100000
Total PAC-2 Volume 200100
14Converting a PAC volume back to Cayenne
- (PAC Volume)(PAC Concentration) ST Mass
- (200100 m3)(10mg/m3)(1kg/1E6 mg)2.001kg of
Cayenne - If the Sultan of Absurdistan tries to fry a
chicken using just 2kg of Cayenne and nothing
else, he wont like the result.
15Using the idea
- Combined several real materials into one
pseudo-material - Called it a representative pseudo-material
- Did the math and conversion in a classified
document - Used the pseudo material values in a sensitive
unclassified document that we can share with
people who have need-to-know
16An Important Distinction
- Didnt lie
- Told the audience that these are representative
values - Told them why the actual source term is concealed
17On the Day that it Actually Happens
- Need-to-know changes
- Emergency health and safety provisions can drive
the Classified Matter Protection and Control
(Very important to keep contractor and federal
roles in mind during this process.) - Pantex sponsors DOE clearances for certain
off-site agency government officials. This
allows a range of information releases for this
event.
