CRISLYN MAY KROON

Provided radiation protection support during R-27 refueling and system upgrade at Columbia Generating Station, ensuring compliance with ANSI 3.1 and site procedures. Monitored radiological conditions, minimized exposure, and enforced ALARA principles through job coverage. Assisted in training junior RP/HP technicians and participated in emergency response team activities.

Led radiation safety efforts during the decommissioning of key plant components, ensuring strict adherence to ALARA principles and NRC regulations. Managed radiation protection programs, supervised radioactive material transfers, and conducted radiological surveys to minimize exposure. Mentored a team of RP professionals, maintaining certifications and ensuring safe decommissioning practices. Provided plant-wide briefings, maintained detailed records, and monitored airborne contamination, ensuring regulatory compliance. Supervised work in alpha-contaminated areas, supporting safe decommissioning progress.

As an RP Count Room Technician, I process air samples from Radiologically Controlled Areas (RCA) and Contaminated Areas (CA) to monitor airborne contamination, ensuring timely and accurate reporting. I perform radiation surveys on items leaving the RCA, verifying compliance with release criteria and approving unconditional release when appropriate. I assist in the decontamination of radiation workers exiting the RCA, ensuring they are free of contamination and safe for unrestricted access. I maintain accurate documentation of Personal Contamination Events (PCE), ensuring compliance with regulatory standards. My role is vital in supporting radiological safety and ensuring both personnel and materials meet safety requirements during reactor shutdown activities.

Performed radiological monitoring by collecting air samples, conducting routine surveys, and tagging radioactive waste. Ensured proper radiological postings and RAM tags, assisted in shipping surveys, and provided job coverage for craft personnel in radiological areas. Maintained accurate records, controlled radioactive materials during shutdown refueling, and assisted in down-posting areas. Conducted routine source checks on radiation detection equipment.

Supported the Dry Cask campaign by collecting, installing, and counting air samples. Ensured proper radiological postings and verified RAM tags on radioactive material bins and boxes. Controlled and surveyed materials exiting the spent fuel pool for compliance with radiological safety standards. Assisted Senior Technicians with dry cask storage job coverage and performed neutron surveys. Conducted routine source checks on radiation detection instruments to ensure operability.

Collected, counted, and installed air samples. Ensured accurate radiological postings and proper RAM tags on radioactive material bins/boxes for short/long-term storage within the RCA. Provided RP support for job coverages involving neutron radiation, under Senior HP/RP technician supervision. Conducted routine source checks on radiation detection instruments, ensuring operability across the plant and inside RCAs. Performed routine surveys throughout the plant and assisted Senior Technicians with HRA job coverages, including up-posting and down-posting areas.

Collected and installed air samples, performed routine surveys, and conducted initial radiological surveys on pressurizers and BioShields. Rated and tagged radioactive waste, ensuring proper radiological postings and RAM tags on materials for short/long-term storage within the RCA. Performed shipping surveys and provided RP support during head lift and RCP evolutions. Assisted with refuel activities and cavity decontamination (Upper Internals & Lower cavity). Supported workers in HRA areas, collecting and installing air samples and ensuring proper PAPR usage. Assisted senior technicians with radiological posting changes and modifications.

Collected and installed air samples, conducted routine source checks on radiation detection instruments, and performed SOP smear and clear procedures for items exiting a CA in the RCA. Rated and tagged radioactive waste, ensuring accurate radiological postings and RAM tags on materials for short/long-term storage. Provided low-risk job coverage for valve breaching and performed daily routine surveys, ensuring compliance with radiological safety standards.

Collected and installed air samples, performed and documented radiation and contamination surveys in the RCA and CA, including overhead and HRA surveys. Verified and posted areas accordingly, conducted pre- and post-job surveys, and performed HRA surveys in the torus. Managed incoming radioactive materials (RM) to and from the RCA, assisted senior technicians in the pre-release process for items exiting the RCA, and smeared and cleared items from the CA. Ensured proper radiological postings and RAM tags on materials, and conducted dose rating and tagging of radioactive waste. Verified LHRA/HRA door locks, provided low to medium-risk job coverage, and performed routine surveys.
