LaSalle is requesting the following information:
1.
Does your site use lanthanum rods for welding?
2.
Any other information such as site contact, application, etc.,
if available.
Background; We had some Th-232 alpha issues in our spring outage related
to grinding weld rod/tips. Out of that came the following action; RP
to benchmark industry to see if other stations use lanthanum weld rod
(lanthanum rods do not contain natural alpha emitter isotopes but
provide as good a weld). From benchmark, determine if such rods should
be considered for use at LaSalle. These type of rods are much more
expensive than the regular weld rods.
Thanks,
