PWRs and carbob14 -Reply
The USNRC did work on C-14 in power reactor waste in the early 80's in
preparation for regs on low-level waste disposal. Appendix C of the FEIS for
the regs may be helpful. It's in NUREG-0945, Vol. 3.
For technical info try "Radiochemistry in Nuclear Power Reactors" available
online at http://www.nap.edu/readingroom/.
Donald Filion of Rochester Gas & Electric did some work on C-14 effluent
releases from power reactors. I believe he is retired now. Jason Jang of the
USNRC is familiar with his work. Contact me if you wish additional info for
contacts.

Carbon 14 in primary circuit coolant water of PWRs
I am investigating the state of knowledge concerning the origin of Carbon 14
in primary circuit coolant water of pressurised water reactors. I understand
that Carbon 14 arises principally from the neutron activation of naturally
occurring Oxygen17 and Nitrogen 14.
I am trying to find out when Carbon14 was first recognised as a PWR
radioactive waste issue.
Also interest is what can be done to minimise the product of Carbon14 in
primary circuit coolant water of PWRs.
I am particularly interested in the disposal of MODIX resins used to treat
primary coolant. The MODIX resins trapping Carbon14 and the problems this
causes for disposal.
Any help on answering my questions would be most appreciated.
