Enclosure 5 - Decommissioning Cost Estimate for License SNM-95 (Special Nuclear Materials)
Section A.3.4 Facility Description License Numbers and Types The Pennsylvania State University maintains license number SNM-95 issued by the Nuclear Regulato1y Commission a Special Nuclear Materials (SNM) license.
Types and Quantities of Materials Authorized The following are the licensed materials and quantities pennitted under SNM-95:

anaged
. The c covered by this license is six.
Routine surveys are perfo1med by Radiation Protection staff once per calendar quaiier to assure that safe working conditions are maintained. No1mal operating procedures require that radioisotope laboratories minimize contamination. Typically, surveys show no removable contamination above background (approximately< 50 dpm/100cm2) on surfaces and equipment using liquid scintillation counting (LSC) and Geiger meters. Penn State maintains a "no contamination" policy and any finding above background is promptly addressed and decontaminated.
Because of this continuous characterization of the radiation environment, n01mal decommissioning typically requires only the removal of radioactive materials, or solutions, and radioactive waste consisting of paper, plastic, and glass lab ware followed by appropriate surveys of the facility and equipment. Decommissioning surveys ai*e a routine paii of the radiation safety program when authorized users either relocate or te1minate.
Description of Facilities The Pennsylvania State University is a large educational institution serving more than 45,000 students and more than 2500 faculty. Research under this license cmTently takes place in two (2) buildings exclusively at the University Pai*k (UP) campus. Some buildings shai*e both educational and reseai*ch Inissions; others are designed as reseai*ch laborato1y buildings. Within a building, the use of radioactive material can be in many or just a few locations as approved by the University Isotopes Committee. As the type and emphasis of research changes over time, the occupancy of a building may also change and interior spaces ai*e often remodeled.

Enclosw-e 4: Decommissioning Cost Estimate for License SNM-95 Table 2 - Buildin s and Rooms Campus Number of UP UP Within any given approved laborato1y space, researchers are encouraged to limit work with radioactivity to as small an area as possible, e.g. one bench top. Individual instmments and equipment that are used to store or process radioactive samples are labeled with a Caution Radioactive Material label.
In summa1y, standard operating procedure is to protect the bench surfaces from contamination with absorbent material. Generally, no liquids are disposed of by means oflaborato1y sinks but, rather, are collected for disposal by Radiation Protection staff. Only accidental or incidental ( e.g. secondaiy glassware washing, etc.) discharge via a laborato1y sink is permitted unless sink disposal is approved by the University Isotopes Committee (UIC).
CmTently all SNM radioactive material use at UP is in traditional laborato1y setting (i.e. dedicated rooms or spaces with rooms having walls and doors). To simplify estimating the decommissioning costs, a Reference Laborato1y (RL) will be defined. This generic laborato1y consists of a single room used for peifonning research with radioactive materials as well as non-radiological research. Actual room sizes vaiy between approximately 100 ft2 to 1500 ft2 and the RL will be assumed to be 600 ft2 (20 ft wide by 30 ft deep by 10 ft high). Section A.3.5 contains more detail as to the contents of a RL.
Radioactive Waste On-Hand Before Decommissioning At the present time there is no SNM waste on hand. Due to the limited quantities in possession cmTently, SNM waste On-Hand at the time of decommissioning will be treated as zero. The info1mation provided below is almost entirely other byproduct waste disposal. The info1mation provided below is included as reference only and consideration as to typical types, volumes, and cost of disposal.
All wastes with less than or equal to 120 day half-life ai*e held for decay for at least 10 half-lives, then surveyed and released as non-radioactive waste. All long lived wastes are shipped to an appropriate waste disposal facility.
There ai*e no SNM wastes on-hand prior to decommissioning. Since some wastes will be generated during decommissioning, the wastes costs are based on the prior six yeai*s of waste shipment data.

It is assumed that nonnal operations continue up until the date the contractor comes on site. The contractor will need to first fainiliarize themselves with the facility and define the scope of work.
The Radiation Protection Office and Breazeale Nucleai* Reactor Facility maintain all records pe1iinent to the use of radioactive materials under the licenses. These include receipts, invento1y, locations of use or storage, waste invento1y, personnel, and sealed sources. The records are kept electronically in a database and updated as the record is generated (i.e. invento1y is updated as stocks are received; lab survey data is updated soon after the survey is completed, etc.) Laborato1y surveys are perfonned on at least a quaiierly basis and paper records kept for at least three yeai*s; therefore, a review of these documents will demonstrate the recent levels of contamination which may be expected. Locations of all licensable and generally licensed sealed sources are kept.
Historical Site Assessment The following records are available in the Radiation Protection Office (RPO) with regard to historical use of radioactive materials:
A) Paper smvey repo1is of laboratories where radioactive material has been used for the past three years. Smvey repo1is are not to scale, but represent the pertinent fixtures and equipment used for radioactive materials work. Smveys may extend to non-use areas and equipment that may be in a paiiicular location. Smvey repo1is typically record the radionuclides recently used and may not reflect all historical uses in a paiiicular location; however, historical purchase records ai*e available.

- Decommissioning Cost Estimate for License SNM-95 Page 10 of 20 December 2025 B) Paper final survey reports of laboratories that have been decommissioned and released for unrestricted use after cessation of radioactive materials use. Survey reports are not to scale, but represent the pertinent fixtures and equipment used for radioactive materials work. Portable equipment released in a final survey report is not identified with specific information such as manufacturer, model or serial number. Once an item of equipment is determined to be free of radioactive contamination, the Caution Radioactive Materials label is removed and it is released to unrestricted use.
C) A listing of all locations by user, nuclides, building and room number where radioactive materials were ever authorized under license.
D) A listing of locations where radioactive materials are currently authorized.
E) A database of all licensable, generally licensed, and sealed sources currently in possession. Sealed sources are inventoried as least semi-annually by the RPO and all disposals of sealed sources are by the RPO. A concerted effort has been made to dispose of sources no longer needed; therefore there should not be any surprise discoveries of sealed sources.
F) Leak test records for all sealed sources.
G) A database of all radioactive waste currently being held in storage, whether for decay-in-storage, or ship-out.
H) Scale floor plans of buildings are maintained by the Office of the Physical Plant, and available in the Facilities Information System (FIS) but survey maps used by the RPO show major room components.
Other Activities In addition to a records review, a visit to a representative sampling of locations will be made to confirm the starting radiological conditions. Based upon the current level of use, Penn States no contamination policy, and a review of past surveys showing no contamination in labs, it can be concluded that radiological conditions are already within the release criteria.
The contractor will prepare the actual decommissioning plan for regulatory review. This will define the scope of work, the radiological conditions of the site, and provide a plan for action. Upon approval by the regulator, a working plan will be developed to include a strategy for systematic decommissioning surveys along with manpower and equipment requirements.
The following table summarizes the work days associated with these activities. The estimates are from Ecology Services, Inc. and Chase Environmental, Inc. and are the worst case values for a particular activity. Other than the characterization activity in Table 9, all others are independent of the number of laboratories. In addition, the final work days for this step are divided by the number of labs currently in use to obtain the work days per lab, which is the basis for all following tables.

Lab Section A.3.7 Decontamination or Dismantling of Components (Work Days)
Based upon the continuous survey and decontamination efforts conducted during the n01mal radiation safety surveillance program, there are few components which might need to be addressed in this catego1y.
Fume hoods - A ve1y small number, less than three (3), of chemical fume hoods are used with SNM radioactive materials. For these hoods, removal of interior air baffles will be done to reveal hidden surface areas and the connection to the exhaust duct. These areas will be checked for contamination.
Sinks -Although liquids are collected by the RPO, within a posted laborato1y one sink per lab is assumed to possibly be contaminated from accidental spillage in the sink or for personal decontamination. To ensure contamination has not lodged in the drain system, the sink traps will be disconnected to survey interior of drain piping.

$132,540 Section A.3.14 Packing, Shipping, and Disposal of Wastes Note: Labor costs for waste processing is included in this section and not in the above analysis.
Packaging Material Costs Because of the University's "no contamination" policy, there would be a minimal amount of waste generated from decommissioning. There are no areas in which protective clothing, other than gloves, need to be worn. Penn State owns enough chy and liquid waste containers to handle all waste on-hand and residual liquid and chy collection beyond the n01mal waste generation volume. The only waste sti*eam anticipated will be chy waste consisting of wipe down towels, gloves, and miscellaneous paper and/or solid items. Note that no labor costs are associated with packing materials needed. Using the Reference Laborato1y, the following packing materials will be needed:

$1,994 Shipping Costs Once a laborato1y has been decommissioned, there is labor cost associated with the collection of the waste containers from the lab, documenting the shipment, and packing the tiuck. These costs are addressed below. Note that since all lab wastes will be shipped at one time, the costs shown are for ALL labs.
To calculate the number of standard 40 foot semi-ti11ck loads needed, the volume of a 40 foot trailer (https://afmeng.com/HotStamping/Hot Stamping Info1mation/Hot Stamp Machine Shipping/fmck Sizes.pdf?ID=815 )
is 3083 ft3. The total volume to be shipped is:

$15,360 Waste Disposal Costs For the Reference Lab, one diy box and one gallon of liquid per lab is assumed to be generated.
Historically, the cost per pound is more consistent year to year so this DCE will estimate disposal cost by weight rather than volume. The following assumptions apply to this estimate:
Each box ofD1y Active Waste is assumed to weigh 100 pounds, 6 boxes generated Each 30 gallon illlllll of liquid waste is assumed to weigh 175 pounds, 1 di11m generated Each 55 gallon illlllll of metals is assumed to weigh 175 pounds, 1 di11m generated Page 17 of20 December 2025 OFFICIAL USE ONLY - SECURITY RELATED INFORMATION OFFICIAL USE ONLY - SECURITY RELATED INFORMATION

Enclosw-e 4: Decommissioning Cost Estimate for License SNM-95 Section A.3.15 Equipment and Supply Costs Smears and related supplies (gloves, vials, and scintillation fluid) are based on MARSSIM criteria for final surveys. Estimating an average of 20 smears per lab, and 6 labs to be surveyed, indicates a need for approximately 120 smears, to be analyzed via liquid scintillation counting. Purchase costs for anticipated packaging supplies are noted in Table 17.
hlstrnmentation needs would include pancake GM survey meters, low energy sodium iodide detectors, and an alpha probe survey meter.

$12,663 Section A.3.16 Laboratory Costs It is not anticipated that any analyses will need to be perfo1med by an independent third pa1ty laborato1y; however, to be conse1vative, this DCE includes outside laborato1y se1vices to analyze laborato1y smear smveys for these 6 labs being decommissioned.
Third-paity laborato1y estimates are $155 per lab. With 5 active labs being decommissioned, the Laborato1y Cost estimate can be detennined.
