Regardless of the fare rules, I would expect that it could be difficult and frustrating to obtain a refund from Ukraine Airlines. This might be a case where it could be useful to pay to use an excellent real live human travel agent (NOT an on line travel agent) rather than purchasing directly from the carrier.
If the price is right, perhaps the OP can purchase a RT ticket (for some cheap return date) and throw away the return portion, assuming that Ukraine wouldn't go after him for the difference to the correct one way fare.
