Yes,

I responded to his questions. It was about the difference between zirc fire and Hydrocarbons fire.

Brian McDermott, NSIR, may have been in the OPCEN. Ghani may have responded to this request earlier and provided him information about what the chemistry of the emissions is during a zirc fire.

Thanks

I reported to the Ops Center at 9:00 a.m. as you requested. The RST Director (Fred Brown) said he needed me to meet with the NR rep. So I did. Who is Brian McDermott and what is he doing?

Jason did you discuss with Brian McDermott and if not, please contact him. Brian’s phone number is (301) 415-2334 but you may need to call the opcen.

Thanks again all!

While the nosepieces of the assemblies are under water, the oxidation is in steam – so chemistry is like in-vessel. Most significantly, Ru release is not favored. Under pure air, Ru oxide could be evolved. Late in boildown the Zr outer canisters could air oxidize.

The Op Center requested a response to the following question to Jennifer Uhle.

“Can someone call Brian McDermott and provide him information about what the chemistry of the emissions is during a zirc fire. Please do so sometime today, preferably before lunch.”

Brian’s phone number is (301) 415-2334.

Please let us all know if any of you have addressed the question and what was the answer for us to follow up.

Thanks,
C.
