A Study on the Clearance Level(draft) for the Steel Scrap from the KRR-1 ＆ 2 Decommissioning
Abstract
The exposure dose form recycling of a large amount of the steel scrap from the KRR-1＆2 decommissioning activities was evaluated, and also the clearance level(draft) was derived. The maximum individual dose and collective dose were evaluated by modifying internal dose conversion factor which was based on the concept of effective dose in ICRP 60, applied to the RESRAD-RECYCLE ver 3.06 computing code, IAEA Safety Series 111-P-1.1 and NUREG-1640 as the assessment tool. The result of assessment for individual dose and collective dose is 23.9 Sv per year and 0.11 manSv per year respectively. The clearance levels were ultimately determined by extracting the most conservative value form the results of the generic assessment and specific assessment methodologies. The result of clearance level for radionuclides( , C ) is less than 1.1410 Bq/g to comply with the clearance criterion(maximum individual dose : 10 Sv per year, collective dose : 1 manSv per year) provided for Korea Atomic Energy Act and relevant regulations.s.
