The electrolytic separation factor, α, has been measured for 17O and 18O at Pt and Ni anodes in both light and heavy water solutions of
6MKOH
as a function of current density. For oxygen‐17, isotopic separation effects were not observed, within the experimental uncertainty of ±2%, under all conditions studied. For oxygen‐18, three is a small difference of 2% in α values between Pt and Ni in both light and heavy water solutions, but there is no significant difference in α values between light and heavy water solutions. In light water solutions, the separation factor at Pt is small,
α(18Ofalse)≤1.02
for
i≥0.1 A/cm2
. This value agrees reasonably well with theoretical estimates.

Five analysis methods were compared for the determination of boron in heavy water moderator: isotope dilution mass spectrometry, spectrophotometry, neutron activation, inductively coupled plasma -atomic emission spectrometry, and ion selective electrode potentiometry. Ten samples were analysed by each method; the results showed close agreement between all of the methods. Only mass spectrometry achieved the required precision (< 1% rsd) for samples taken during initial reactor operation, but all of the methods achieved sufficient precision (
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
