1. Thomas Jefferson National Accelerator Facility
Jefferson Laboratory
Patty Hunt, P.E., CIH
Located in newport news virginia, the facility has been in operation since employs around 850 full time staff and about 1000 user group members, consist of physicists from universities us and abroad.

2. Scope/Background Waste Minimization Impact on Waste Shipments
Dept. of Energy Laboratory
~850 employees
>2000 scientists from 18 countries
7/8 mile racetrack Accelerator
superconducting
4 experimental Halls
12 billion electron volts
I will talk in general about the science, and then where the lab is headed and the associated impact on waste production

3. Laboratory Mission
So as the slide says , in 1968 some ov the components of the proton were discovered and named quarks. They have funny names, the up down, the strange, the charmed…
The quarks are held together by a force/particle called the gluon

4. Jefferson Lab’s Scientific Purpose
Study how quarks and gluons combine to form
protons and neutrons
At Jlab, an electron beam is used to probe the protons in a target. The target material must be very simple, so low atomic number elements are typically used, for example, hydrogen, deuterium, lithium… The electron is much smaller than the subcomponents.. It interacts with the quarks//gluons and the result is a nuclear fragment. Magnets steer the scatter electron beam away to a dump, and the fragments are directed towards detectors. This takes place in an experimental endstation, or hall, as we call them.

11. Radioactive Waste Significant Project: Hall C Beam Dump Upgrade
Used ppe
Activated metals
Activated concrete
Solidified Decon Gel™

12. Hall C
Typical experiment detector setup in the end stations, note the size comparison of the equipment to the people is depicted. Beam comes in from the accelerator and hits the target. Small z targets 1 or 2 protons Deuterium Tritium lithium. Fragments are scattered and dectectors pick up signals that identify the fragments

22. Reduction in Hazardous Waste Shipment Cost Eductor System from Chemroom Fume Hoods lowers number of lab packs

23. Reduction in Lab Packs Insert hollow tube into waste acid bottle B
Turn valve at A
Eductor pulls waste acid out and it is diluted 20:1
Diluted waste is then directed to a gravity fed rinsewater line to the acid neutralization plant
Cannot do this for heavy metals- only niobium

24. Shipments for 2015, 2016 Radioactive Waste
2015: $ 35,000 (savings too soon to tell)
2016: $ 35,000
Hazardous Waste
2015: $ 25,000 (70% cost reduction)
2016: $35,000
