ANSI 3.1-2014 and the Supplemental Workforce of Radiation Protection Technicians.

Attrition in the supplemental workforce of radiation protection technicians continues to present challenges in supporting the US nuclear power industry with contract technicians during refueling outages, major projects, and decommissioning. Industry wide adoption of ANSI 3.1-2014, Selection, Qualification, and Training of Personnel for Nuclear Power Plants, can help overcome these challenges by accelerating the training and development of technicians in the supplemental workforce by applying the systematic approach to training (SAT).

Detection threshold of large area wipes.

A methodology is provided to determine how much removable surface contamination can be detected on a large area wipe by surveying the wipe with a portable survey instrument. Equations are provided to relate levels of removable surface contamination to survey instrument readings from a wipe, considering the effects of wipe size and background. Justification is provided to demonstrate that action limits have not been exceeded if contamination is not detected on a large area wipe provided the parameters of the survey are appropriately controlled.
