Winger Claire Flowers opened the scoring in the second minute with the first of her 4 tries. This was quickly followed through by April Dent as Wales built up an unassailable lead that saw them 41 - 0 up at half time.
Centre Louise Rickard crossed for a hat trick of tries as the forwards laid the platform for the backs to demonstrate some excellent running rugby. Further tries came from Sue Jones, Karen Mayze and Kylie Wilson (2) to bring the curtain down on a good all round team performance.
Wales now face Italy on Monday (KO 3:30pm GMT) having finished top of their pool.
Nearly 40 players were involved in the first Wales Under 18 training session of the season. WRU National Performance Manager Gethin Watts is excited at the potential shown by the group and expects the Regional Under 18 Championship to hone their skills even further.
