Agenda
- NRC Mission
- Reactor Oversight Process (ROP)
- 2022 Safety Performance Overview
- Control of Radiological Effluents
- Question-and-Answer Session 4
OUR MISSION To license and regulate the nations civilian use of radioactive materials to provide reasonable assurance of adequate protection of public health and safety and to promote the common defense and Region III Office, Lisle, IL security and protect the environment.

How do we meet our Mission?

Monticello 2022 Assessment Summary
- Operated safely and in a manner that preserved the public health and safety and protected the environment
- 2225 hours0.0258 days <br />0.618 hours <br />0.00368 weeks <br />8.466125e-4 months <br /> of direct inspection
- All Green Performance Indicators
- One Green Findings with Associated Non-cited Violations
- Failure to Maintain FLEX Equipment Consistent with the Requirements of 10 CFR 50.155(c)(2)
Control of Radiological Effluents 12
Overview
- Nuclear power plants need to discharge radioactive effluents in small amounts in order to operate and have been doing so safely since initial start-up
- Rules limit the amount that can be released to ensure they are a fraction of what is received from background sources
- Release information is publicly available and inspected by the NRC 13
Dose
- A measurement of the energy imparted by radiation
- Conventional units used are mrem (millirem)
- Can be thought of as the overall risk from radiation to a person
- Average dose an individual receives per year from natural sources of radiation (sun, soil, etc.) is about 300 mrem 14
Regulations
- Focus on limiting the dose to people living around the site
- Nuclear power plants must limit dose to the public to 25 mrem/year
- Plants are designed to operate well below 25 mrem/year
- Monticello typically runs with the maximum dose to a member of the public below 0.1 mrem/year 15
Land Use Census Public GPI Health Effluent Controls
& Safety REMP 16
Land Use Census
- How the public is exposed to radiation depends on how the land around the plant is used
- Plants annually perform a census to identify changes in how the land is used
- Looks for things such as large gardens, dairy cows, where residents are located, etc.
17
Land Use Census Public GPI Health Effluent Controls
& Safety REMP 18
Effluent Controls
- We are using effluent as a generic term to describe radioactive material released from the site in gaseous or liquid form
- Effluent controls ensure that what is being released is monitored and controlled to ensure dose limits are met 19
Effluent Controls
- Doses to the public are too small to measure directly
- Sites sample and analyze effluents from the plant piping or tanks they are being released from
- Information from the land use census used to model how an individual would be exposed to the effluent release
- Doses are calculated based on the model 20
Effluent Controls 21
Land Use Census Public GPI Health Effluent Controls
& Safety REMP 22
REMP Radiological Environmental Monitoring Program
- Measures radiation in the environment during the lifetime of the plant
- Determines if any measurable levels of radiation are from plant operation
- Determines if results are commensurate with the radioactive effluents 23
REMP 24
Land Use Census Public GPI Health Effluent Controls
& Safety REMP 25
GPI Groundwater Protection Initiative
- Provide timely detection and effective response to inadvertent on-site releases to groundwater in order to prevent migration off-site and to quantify impacts on decommissioning
- Improve communication with external stakeholders
- Perform program oversight to ensure effective implementation 26
GPI
- How does the groundwater move?
- Where is there potential for leaks?
- Monitoring wells established in strategic locations based on hydrology and risk ranking
- Pumping contaminated water out of the ground for appropriate handling
- Protocols established between site and State/Local governments 27
GPI 28
Recent Tritium Leak
- Site identified elevated tritium levels in one of the GPI monitoring wells during routine monthly sampling
- Site notified the State and NRC of the elevated levels
- Sampling frequencies of nearby monitoring wells increased
- Site started investigation to determine source of the leak 29
Recent Tritium Leak
- Site identified source of leak in pipe that runs between the reactor and turbine buildings, which have a small gap between them.
- Leak was captured and rerouted back into the plant
- Site started recovering contaminated groundwater
- Stored in tanks on-site and reused as plant make-up water
- Site started installing additional monitoring wells 30
Recent Tritium Leak
- Routine sampling of monitoring well indicated some of the leak was again making it to groundwater
- Site shut down the plant to replace the section of pipe
- Permanent repair was originally planned for the routine maintenance outage scheduled in April 2023 31
Recent Tritium Leak
- Site continues to monitor location of tritium
- Monitoring well sample frequency adjusted for each well based on current conditions
- Evaluation for additional monitoring wells continues
- Recovery of contaminated groundwater routinely adjusted for current conditions
- Sites actions are aimed at preventing uncontrolled migration of the tritium off-site 32
Recent Tritium Leak
- Risk from off-site release
- The amount of tritium leaked to the groundwater would not pose a health concern even if all of it reached the Mississippi River
- Dose to a member of the public would be well below 1 mrem
- Remember, 300 mrem/year from natural sources 33
Recent Tritium Leak
- Even though there is no health concern, it does not mean it is okay to do nothing
- NRC expects effluents to be released in a monitored and controlled fashion
- Site had to identify and stop the leak
- Recovery of contaminated groundwater to mitigate off-site release through groundwater is expected
- Extensive monitoring of the groundwater will ensure that any off-site release through the groundwater is appropriately accounted for
- NRC will verify appropriate control 34
Inspections
- The NRC has specialized inspectors perform periodic on-site inspections of the programs discussed today
- The NRC maintains at least two resident inspectors at each site to oversee the day-to-day operation of the site
- NRC will continue to follow the sites actions through the routine inspection program 35
Inspections
- Review implementation and results
- Observe routine effluent sampling and analysis
- Walkdown effluent systems and radiation monitoring equipment
- Review maintenance and calibration records
- Review quality assurance programs
- Review discharges
- Walkdown and observe GPI program elements
- Review monitoring well results and licensee evaluations of results
- Observe sampling activities
- Review laboratory results and licensee evaluation of results
- Review quality assurance programs 36
Annual Reports Nuclear power plants are required to submit annual reports summarizing effluent releases, on-site groundwater monitoring results, and REMP results.
