Scott A. Thompson Ol(LAHOMA Kevin Stitt Executive Director Environmental Governor Quality May 31 , 2022 Mr. Jeff Lux, Senior Project Manager Environmental Properties Management LLC 615 N. Hudson; Suite 200 Oklahoma City, OK 73102 Re: Uranium Daughters in Groundwater Cimarron Environmental Response Trust, NRC Lice nse No. SNM-928
Dear Mr. Lux:
Thank you for the subject letter, dated May 2, 2022, in response to an infom1atio n request by the Nuclear Regulatory Commission (NRC). As a Beneficiary of the Trust, DEQ has the following questions, intended to clarify the subject letter, and perhaps expedite NRC approval of the Decommissioning Plan (DP) . DEQ does not require a direct response.
In Attachment 3, should the third and fourth table both be labeled " Activity (pCi/µg) of total U"? Both appear to describe the same four samples, but the third table appears to describe calculated activity of each isotope per microgram of material and the fourth appears to describe calculated activity of each isotope as a percentage of the total activity of the sample.
The section " Daughter Radionuclides in the Feedstock" estimates the time for various Uranium daughters to reach seven half-lives and approx imate the ac ti vity of the parent isotope. For the decay chain for the remaining Uranium-235 (U-235), would the time fo r Protactinium-231 (Pa-231) to achieve the act ivity of the parent be *'over two centuries", which is less than one half-life (32,760 years) for Pa-231 , or "over two hundred millennia?
Simila rly, for the decay chain for the remaining U-238 , should the time for "newly-grown U-234" (i .e., not received in the feedstock) to achieve the same acti vity as the U-238 be " most of two millennia which is less than one half-life (245,500 years) fo r U-234) or *'well over a m illion years"?
