Lessons learned from a NUREG-0737 review of high-range effluent monitors and samplers

Conference ·
OSTI ID:6221748
Shortly after the onset of the accident on 3/28/79 at Unit 2 of the Three Mile Island Nuclear Power Station, the upper range capabilities of its real-time monitors for gaseous, radioiodine and particulate effluents to the atmosphere were exceeded. Subsequently, the NRC required extended range gaseous effluent monitors and an improved capability for the obtaining of frequent samples of radioiodines and particulates at the concentrations that would be anticipated in effluent steams under accident conditions (NUREG-0578, NUREG-0660, NUREG-0737, Items II.F.1-1 + II.F.1-2). In 1983 an on-site post-implementation review of their installation and operation was initiated by the NRC Region I. The results from nineteen such reviews indicate that the licensees have adopted a variety of approaches to meet the NRC's requirements ranging from the installation of completely new commercial modules to improvised additions to existing monitors and samplers. Some advantages and drawbacks of these various approaches are summarized. 12 refs., 15 figs.
