The Dragons beat the Scarlets 8-6 at Rodney Parade last Wednesday to reach the final of the competition.
Backs Coach Jon Bryant said: “All the hard work and effort that the boys have put in this season has been rewarded by making it to the Uner 18 final.
“Regardless of the result it has been a hugely successful season for us, particularly highlighted by the number of players selected in the extended Wales U18 squad.”
