  1.  Do you perform Reactor Cavity Decon with House Personnel? Supplemental Resources  If not, who do you contract with to perform the work?
  2.  Do you hydrolase the walls or cavity floor
If you do, what areas do you hydrolase? Briefly describe.________________________
______________________________________________________________________

  1.  To what contamination levels do you strive to achieve?
  2.  What deconning agents if any, do you use on the walls and /or floor?
  3.  Which types of materials/chemicals do you decon with? _____mops
________rags _______ Scrub Pads__________ Hydrogen Peroxide
________high pressure washing ___________other, describe

  1.  Do you use any robotics to perform decon of the cavity?
If so, what type

  1.  Generally, how long does it take to decon the cavity? Time from initial RP survey to the time in which refueling re-enters the cavity
  2.  Are other groups working in the cavity in parallel with the decon crew?
If so, briefly describe

  1.  Estimate the amount of exposure in mRem that it takes to decon the Reactor Cavity?
_______100-500 _____500-750 _____>750 mRem

  1.  What recent changes have you made to decrease the time required to decon the cavity and/or reduce the exposure that it takes to achieve your decon goal?
  2.  Do you have a detailed procedure for this activity? If so, would you consider providing a copy for us to review?
