SUMMARY

OF FACILITY ACTIVITIES 2.1 Decommissioning Status During Calendar Year (CY) 2015, the TRIGA Mark F Reactor was in a Decommissioning status.

The major tasks accomplished during this reporting period were:

  • Removal of hazardous material contaminants (Pb and Cd) from the walls and floor of the reactor pit and fuel storage canal. The contaminants were present in the surface layer of epoxy/gunite.
  • Collection of twenty (20) core samples from within the reactor pit and fuel storage canal.

2.2 Facility Status The MkF reactor was in OECON status during CY 2015. The reactor pit/canal was remediated of hazardous contaminants (Pb and Cd) and core samples extracted.

2.3 Decommissioning Schedule Removal of the Epocast coating and about % " of gunite from the walls and floor of the pit and fuel storage canal was conducted during AprU-May 2015. FoUowlng completlon of this task, eight (8) core samples were collected from the MkF pit walls and floor during July-August 2015.

Sample results showed measurable quan1ltles of Co-60, Eu-152 and Eu154. StatJstlcal analyses Indicated an addftlonat twelve (12) core samples would allow fuU characterization of the volume of material requiring remediation. These addltlonal samples were acquired in December 2015. The plan and schedule for completion of the decommissioning of the Mk F is dependent on the results of the characterization of the gunite. steel, concrete and soil contained wlth!n the core samples. Characterization of the depth and amount of contamination is expected to be complete in ear1y 2016. This will determine the volume of material requiring removal and aHow a statement of work to be written for structural analysts and excavation.

2.4 Radioactive Material Shipments During 2015 two (2) separate radioactive shipments or transfers were made from the Mk F faclllty to different facllJties.

On June 24, 2015, two excepted package-llmlted quantity wooden crates containing spent fon exchange resins were shipped from GA to Energy Solutions Bear Creek. PhUotechnics acted as broker. The packages together contained 4.0 mCi solfd oxide Co-60 and Cs-137. In addition. one row specific activity (LSA-11) fifty.five (55) gallon drum containing lead/steel was 1
