Title: Quarterly Environmental Radiological Survey Summary Third Quarter 1998, 100, 200, 300, and 600 Areas

Abstract

This report provides a summary of the radiological surveys performed in support of near-facility environmental monitoring at the Hanford Site. The Third Quarter 1998 survey results and the status of actions required are summarized: (1) All of the eighty-five environmental radiological surveys scheduled during July, August and September were performed as planned. Fifty-one of the surveys were conducted at Project Hanford Management Contractors (PHMC) sites and thirty-four at Environmental Restoration Contractor (ERC) sites. Contamination above background levels was found at seventeen of the PHMC waste sites and two of the ERC waste sites. Contamination levels as high >1,000,000 disintegrations per minute (dpm) per 100 cm{sup 2} were reported. Of these contaminated surveys nine were in Underground Radioactive Material (URM) areas, three were in unposted areas and seven were in contamination areas. The contamination found within four of the URM and three of the CA areas was immediately cleaned up and no further action was required. The remaining five URM and two unposted sites were posted and along with the five CA sites will require remediation. Radiological Problem Reports (RPR's) were issued and the sites were turned over to the landlord for further action as required. (2) During the second quartermore » of 1998, 1.2 hectares (3.0 acres) were stabilized and radiologically down posted from Contamination Area (CA)/Soil Contamination (SC) to URM. (3) Four hectares (10 acres) located south and west of B-Plant were posted as a radiological buffer area as a result of a contamination spread. This off-normal occurrence is currently being investigated. (4) Four Surveillance Compliance Inspection Reports (SCIRs) remained open and had not been resolved. Tank Farms Operations has responsibility for the unresolved SCIRs.« less

  • Routine surveys to monitor radiological conditions are performed by Westinghouse Hanford Company`s Health Physics Group. Areas surveyed include the road surfaces, radioactive waste sites, radioactively contaminated areas resulting from spills or releases, outdoor areas near facilities and tank farms located in the 200/600 areas. This report provides the status of radiological conditions in the environment near facilities located in the 200 and 600 areas. The Third Quarter 1990 survey results and the status of actions required in past reports are summarized in this report. 8 figs., 4 tabs.
  • Routine radiological surveys are part of near-facility environmental monitoring, which monitors and helps direct the reduction of the radiological areas at the Hanford Site. The routine radiological surveys are performed by the Southern Area Remediation Support Group and the Site Support Services Radiological Control Group as directed by Environmental Monitoring and Investigations. The surveys performed have included inactive waste sites; outdoor radiological control areas; tank farm perimeters and associated diversion boxes, lift stations, and vent stations; perimeters of active or uncovered waste sites such as burial grounds, retention basins, ponds, process trenches, and ditches; underground pipelines; and road and railmore » surfaces. This report provides a summary of the radiological surveys performed in support of near-facility environmental monitoring at the Hanford Site during the first quarter 1998. The survey results and the status of actions required are also discussed. A waste site survey schedule, Routine Environmental Monitoring Schedule, Calendar year 1998, HNF-SP-0098-9, was developed by Environmental Monitoring and Investigations working with the Southern Area Remediation Support Group and the Site Support Services Radiological Control Group. Environmental Monitoring and Investigations reviews the radiological survey reports and files a copy for historical purposes and reference. Radiological conditions are tracked and trends noted. All sites are surveyed at least once each year. The survey frequencies for particular sites are based on site history, 1,551 radiological conditions, and general maintenance. Special surveys may be conducted at irregular frequencies if conditions warrant (e.g., growth of deep-rooted vegetation is noted at a waste site). Radiological surveys are conducted to detect surface contamination and document changes in vegetation growth, biological intrusion, erosion, and general site maintenance conditions. Survey data are compared with standards identified in HSRCM-1, Hanford Site Radiological Control Manual, as well as previous surveys to recognize possible trends, assess environmental impacts, and help determine where corrective actions are needed. Landlords of the sites found out of compliance with HSRCN-1 may be issued a Radiological Problem Report (RPR) from the appropriate radiological Control Group. Open Surveillance Compliance Inspection Reports (SCIRS) are listed. Surveillance of the active nuclear facilities and inside the tank farms is the responsibility of the facility. These radiological surveys are to determine surface radiological conditions and do not constitute a release survey. Therefore, surveys that detect no contamination in radiological areas do not release the site from control but may result in a posting status change.« less
  • This report provides a summary of the radiological surveys performed in support of near-facility environmental monitoring at the Hanford Site. The Second Quarter 1998 survey results and the status of actions required are summarized. Eleven of the ninety two environmental radiological surveys scheduled during April, May, and June were performed as planned. Sixty seven of the surveys were conducted at Project Hanford Management Contractors (PHMC) sites and twenty five at Environmental Restoration Contractor (ERC) sites. Contamination above background levels was found at twenty one of the PHMC waste sites and two of the ERC waste sites. Contamination levels as highmore » >1,000,000 disintegrations per minute (dpm) per 100 Cmz were reported. Of these contaminated surveys twelve were in Underground Radioactive Material (URM) areas, three were in unposted areas and eight were in contamination areas. The contamination found within six of the UFW and four of the CA areas was immediately cleaned up and no further action was required. The remaining six URM, four CA, and three unposted sites were posted and will require decontamination. Radiological Problem Reports (RPR`s) were issued and the sites were turned over to the Landlord for further action as required. During the second quarter of 1998, 1.2 hectares (3.O acres) were stabilized and radiologically down posted from Contamination Area (CA)/Soil Contamination (SC) to URM. Four Surveillance Compliance Inspection Reports (SCIRS) remained open and had not been resolved. Tank Farms Operations has responsibility for the unresolved SCIRS.« less
