2.0 Site Status Summary

The Waltz Mill site is currently licensed primarily to provide testing, calibration, and maintenance services for contaminated reactor servicing equipment and other reactor components. Radiological contamination in soil and groundwater existed on a portion of the site as a result of the clean-up activities following a 1961 incident at the TR-2 test reactor, waste segregation activities, and nuclear laundry services. Significant contamination was also present in retired facilities (hot cells, hot cell support rooms, and a section of the fuel transfer canal) within one of the site buildings. Contaminants are primarily Sr-90 and Cs-137, with lesser quantities of mixed fission, activation products, and trace levels of transuranic radionuclides. Due to a series of corporate mergers, the licensee for the TR-2 test reactor is CBS, Inc.

Westinghouse submitted a remediation plan in April 1997. NRC approved the remediation plan in January 2000. The licensee has remediated much of the interior and exterior contaminated areas. Remediation activities focused on the three hot cells and supporting facilities in conjunction with work on decommissioning the test reactor. Contaminated soil removal has been completed in the primary exterior contaminated area, although small pockets of contaminated soil and a major contaminated process drain line remain on the site.

In 2008 Westinghouse submitted documentation to revise the remediation criteria for the site. This included the soils and building structures. The revised criteria was approved and incorporated in their license in July 2010.

Westinghouse removed the old test reactor vapor shell in the spring of 2012. In July 2013 Westinghouse completed remediation and Final Status surveys of the G-building former laboratories, which were confirmed by BRP.

3.0 Major Technical or Regulatory Issues

The licensee does not intend to request termination of the license and is expanding site operations through consolidation of business from other sites.
