Lessons Learned: D&D (Decontamination & Decommissioning)

The purpose of this forum is to document on-the-job work experiences. Submit your best solutions for various jobs and processes. This is not to be plant specific, rumor, slander or urban legend. Postings will be reviewed, verified, edited for content, and archived for future reference. Post a summary for review if you wish to post a thesis or position paper. We are getting fewer and fewer, but before the knowledge is lost forever and plant / sites reinvent the wheel; we need to document what we have learned.

Good day everyone,
  I have been tasked to do some research on lessons learned from D&D activities.  I am currently working for the DOE in Idaho.  I need to determine the big issues to be addressed in making a D&D decision.  Any publications, contacts, or personal experiences would be appreciated.

Thanks ahead of time,
Sam

Hi SamA,

Fire off some of your questions here.

Have a Great Week!

SamA:
Hey Moke,

  Actually, my boss wants me to come up with a list of around 20 questions that represent that major issues that need to be addressed.  He would then like me to contact or obtain literature from D&D'ed sites to see how these sites dealt with the issues.
So, I guess my question to you is what questions would you be asking if you had a reactor that was to be D&D'ed?

Hi SamA,

The Record of Decision (ROD) in many cases provides a wealth of information concerning the target area and/or facility in question regarding D&D. In  many cases the ROD does not include all Target Isotopes and other chemical constiuents.

The first question is: have all of the Isotopes and Chemical Constituents been identified to include any surprises. Have the Facility Oldtimers been contacted and questioned?

Major problem is that when the characterization team fails to utilize a systemmatic approach one will be unable to:

Determine the EXTENT and Type of contamination.

Determine proper instrumentation that will enable detection.

When additonal contamination or isotopes are identified in the 11th hour of the game, this is where the problem comes in.

It's like the old scouts of the past doing reconisance (-12 Sp.); tell us who,where,when and why. Positive characterization up front to include forecasting possibilities remain important. Tell the complete story.

Another question being the personnnel involved with the ROD or decision making process.

Are workers qualified? If so, what kind of experience do you have regarding decontamination. Many have little or no experience that may lead to safety and cost overun concerns.

If you are decontaminating a Lab, what controls are in place to deal with unknown constituents? This can be a serious personal safety issue regarding shock senitive and/or pyrophoric material.

Do you have a Chemical Specialist (expert) on your team? If not, you better have one.

Another important D&D question is Safety. If safety is not regarded as the main focus your project may suffer down the road.

I'll be posting additonal stuff later when time permits.

Use the ROD as your Bible and cross check what is procedure against the ROD.

Be back later.

Moke
