Travers, Plasma Arc Cutting j
z;t ht
. Reference (a) forwarded NRC staff questions resulting from our review of your.
,J safety evaluation for plasma are cutting of fuel assembly end fittings. We have reviewed your response submitted by reference (b) and have detennined that you inadequately addressed our concerns on the fonnation of nickle i
carbonyl during the plasma arc cutting process. As previously stated, there are literature references which indicate a potential for the formation of nickle carbonyl, a toxic substance, by plasma cutting of stainless steels.
It (s ;
-is possible that the cutting process may preferentially produce other nickle n.
compounds that present less of a safety hazard. However, there is sufficient i,
evidence of the potential for the fonnation of nickle carbonyl that it must be O
addressed.
t" Please provide the staff with adequate analytical data and literature 4
references describing the chemical processes that affect the formation of nickle carbonyl to further support your position that this compound presents f:L
.no safety hazard. As an alternative, describe the theoretical maxirum nickle carbonyl formation rates based on cutting rates and chemical composition of p
the alloys being cut, and describe the protective measures you will employ to 1;
protect the workers and ensure that toxic substances do not accumulate in the reactor building.
f If you have any question, please call me or my staff.
Sincerely,
