Ireland beat Wales by two points last season at Aberavon.
Ireland Women Head Coach Philip Doyle has made two changes to the side that demolished Scotland at Ashbourne last Friday night for the forthcoming clash against Wales.
Niamh Briggs is named at full-back and Larissa Muldoon comes in at scrum-half. The two players making way, Jackie Shiels and Amy Davis, are named among the replacements.
Hat-trick hero Sophie Spence will again line out alongside Marie Louise Reilly in the second row and Ireland will be hoping that Lynne Cantwell and Alison Miller who both scored a brace of tries against the Scots can have a similar impact against the Welsh. Fiona Coghlan will captain the side and Ashleigh Baxter comes onto the bench in place of Orla Fitzsimons.
Doyle commented, "The performance we put in against Scotland was coming for sometime but we are under no illusions as to the challenge the Welsh girls will present.
"There was only two points between the teams last year so this week we will require a further step up in performance from the group.
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.
