There was a time when the various activities on the Hanford site contributed significantly to civil nuclear energy work, particularly on the fuel cycle end.
The production reactors (I presume mainly N-Reactor, considering the time frame) were used to supply the uranium-233 for the Shippingport Light Water Breeder Reactor core. Hanford was also where the early work on plutonium recycle in thermal reactors (eg, MOX fuel in LWRs) was carried out.
