Committee flags possible data issue in uranium isotopic results

During review of the holding-basin documents, a committee member reported uranium isotope numbers in an appendix that appeared inconsistent with expected natural or depleted uranium ratios. The member noted that natural uranium typically shows about 0.7% U‑235 by mass (common summary values) and that a value around 5% would be anomalous for environmental groundwater samples. Brad agreed to re-check the source tables and confirm whether the figures are extraction errors, scanned-table artifacts, or genuine laboratory results.

"If you measure something with a U235 concentration that's 5% that just can't be right," a member said when pointing to a table; the committee asked Brad to find the original lab table and report back. The item was assigned as a near-term follow-up before the committee finalizes comments on the work plan.
