RSCS is Exhibiting at the HPS Midyear Meeting In Baton Rouge, LA, Feb 9-12th
Posted on February 10th, 2014

Eric Darois and Jay Tarzia of RSCS are exhibiting at the Health Physics Society Midyear Meeting in Baton Rouge LA this week. This topical meeting is focused on nuclear power radiation safety, and will address applying lessons learned from the past to future plant operations.

RSCS has a proven track record of supplying first class management and technical services to commercial nuclear power plants and research reactor facilities. We are well known for developing and implementing effective solutions for complex issues relating to the acquisition, management, and control of nuclear and radiological materials. We have over 20 years experience supporting all aspects of the nuclear fuel cycle including uranium enrichment, new-build activities, operations, and decommissioning at sites throughout the US, Canada, the UK and North Korea.

Our staff’s experience in radiation safety for operating nuclear plants also supports the initiatives of industry consortiums, including EPRI, NEI, and the OECD. We draft and contribute to the development of guidance documents that set the bar for best practices at operating plants.  An example is our participation in the Information System on Occupational Exposure (ISOE) Expert Group on Occupational Radiation Protection in Severe Accident Management and Post-Accident Recovery (ISOE EG-SAM) established by the OECD in 2011 in response to the accident at the Fukushima Daiichi Nuclear Facility.  Intended to provide future guidance on methods to minimize the impact of severe accidents to workers and the public, the ISO-EG-SAM group is drafting a document that identifies factors and aspects which played key roles in achieving good practice on occupational radiation protection during initial and post-accident recovery phases of a severe accident that is due for release in 2014.  Jay Tarzia is a contributing member of this group. 

Attendees of the HPS Midyear Meeting are encouraged to ask us about these select technical services that support operating nuclear plants:

  • Dose Assessments

At sites performing power up-rates, we have modeled the dose implications from increasing BWR turbine flow rates, using Monte Carlo N-Particle (MCNP) calculations to determine the increased dose rates from N-16 and subsequent shielding required to maintain regulatory compliance.  In addition, we perform neutron characterizations in areas around the plant to provide neutron correction factors for worker dosimetry.

  • Subsurface Measurements 

In support of NEI 09-014: Underground Piping and Tanks Integrity Initiative, we have assessed subsurface corrosive conditions proximal to subsurface pipes, systems, and tanks that contain, or may contain licensed radioactive material.

  • Ground Water Modeling

For sites that have adopted the Radiological Groundwater Protection Initiative (GPI) to characterize and monitor groundwater quality, we have performed numerical and spatial groundwater modeling.  This modeling identifies potential sources of groundwater contamination; optimizes the location and design of monitoring wells; and characterizes groundwater flow and monitors groundwater quality to identify changes in groundwater quality or contaminants that may indicate a leak and/or radiological release to the environment.

  • Large Volume Waste Characterization

At sites managing up-rates or decommissioning efforts, our staff has developed systematic sampling survey work plans that integrate MARRSIM and MARSAME statistical sampling methods with state of the art in-situ processes to provide efficient processes to screen large volumes of waste and segregate radioactive materials. These methods effectively reduce the volumetric waste and provide potential revenue streams as free release materials are recycled and reclaimed. 

  • Decommissioning Cost Estimation

To determine required decommissioning trust fund reserves, our unique estimation methodologies provide accurate and dynamic cost estimates to sites that facilitate maintaining decommissioning budgets and schedules throughout the decommissioning lifecycle. Learn more about our proprietary DeCAT software application that we use to develop cost estimates.

RSCS looks forward to meeting with our colleagues in the Health Physics Society to discuss the radiation safety issues that impact our fleet of commercial nuclear plants.
