NMNTI TruPro - Nuclear Sampling System
NRC has been critical of the number of samples taken during initial characterization surveys. Use of TruPro® technology allows for far more samples to be collected in a shorter period of time. Because of the enclosed vacuum system there is a less chance of cross-contamination during collection and handling (material contained in filter). This provides better Quality Controls. TruPro® methodology is used for the radiological characterization of contaminated area, concrete slabs, walls of nuclear power plant containment units and of nuclear process facilities as required by NUREG-1700, Standard Review Plan for Evaluating Power Reactor License Termination Plans as real and credible defensible data matters.
NMNTI`s TruPro® Patented Technology, concrete / metal sampling and profiling tools, provide a superior smarter solution and approach to concrete or bulk material sampling and analysis to the traditional methods of concrete or metal sampling using a wet or dry coring machine or robots. The primary objectives of radiological characterization are to:
- Provide a basis for survey unit classifications
- Provide a basis for identification and distribution of contaminants
- Provide a basis for the lateral and vertical extent of contamination in soils, concrete and systems
- Evaluate the variability of radioactivity
- Evaluate neutron activation of concrete
- Provide sufficient data to determine waste streams
- Provide sufficient data to guide remediation planning/selection of technology
TruPro® Accelerates Facility Clean Out and Demolition by:
- Eliminating Historical Unknowns;
- Minimizing Life cycle Risks, Applying Creative and Innovative Real-Time Deployable Solutions;
- Implementing Effective Sampling and Characterization;
- Identify Program Risks for Problem Areas Enhancing PM Approaches and Principles •
- Ensure Adequate Radiological Controls of Work Areas;
- Improve Site Upfront Understanding and Planning;
- Better Allocate Resources, Raw Materials & Highly Skilled Labor.
TruPro® can be implemented for the sampling of the following:-
- Concrete Floors, Ducting, Cracks , Walls & Ceilings;
- Various Constructional Materials ; Concrete, Brickwork, Granite, Asphalt Blockwork, Plastered Brick, Plastered Block, Tiled Brick, Metal Plate / Pipe and Hardcore;
- Bioshields; Uranium Converters, Refractory, Glass; Brick Structures, Footers;
- Building Sub-surfaces, Bedrock, Clay, Sand & Gravels and;
- Grouted Drummed and Contains ;rized Rubbled TRU Waste
- Nuclear Reactors.
- Rate of sampling, 90 inches in 90 minutes or 17 working days v 55 working days ;
- Cheap and timely quantitative analysis of radionuclides of interest using portable infield instrumentation and radioanalyses;
- Minimal sample turnaround time, approx. 10 to 20 minutes;
- Highly strategic, directional and focused sampling regime to areas of concern maximizing mai resources; ipower ar id financial
- No secondary wastes just sample; no airborne particulate and no water/oil used
- No subsampling of cores;
- Keeps operator dose As Low As Reasonably Achievable;
- Complete Containment of drill cuttings and fugitive tritium;
- Representative sample and quality from bulk materials where the baseline method cannot retrieve high quality
- representative samples;
- Varying masses of sample;
- Reduced chances of cross contamination of samples;
- Increased safety due to less hand on exposure to physical hazards and waste contaminants c ind;
- Sampling incrementally to depths of up to 6 meters.
- Smaller holes (1/2" v 3") means less potential for fracturing concrete or encountering re-bar or tendons
- Increased safety due to less exposure to physical hazards (less weight and no requirement for ` bolting drill to surfaces)
- Reduced project cost and better defensible actionable data
- Reduced dose due to less time in radiation fields as shown below
ALARA Considerations Implemented by Utilizing TruPro® Patented Concrete Profiling Technology
Under Vessel Area 5 sample locations Average Dose Rate: 300 m R/hour
TruPro® Concrete Profiling
12 minutes/location x 5 locations = 1 hour in area
0.3 rem/individual x 2 = 0.6 rem total
CORING
2 hours/core x 5 cores = 10 hours in area
3 rem/individual x 3 = 9 rem total
An RWP is required for this work
Work would be denied (wait until vessel/source term removal)
