No 8 Rachel Taylor will lead the side in her second campaign as skipper.
Seven uncapped players were earlier named in Wales' Six Nations squad but Edwards has resisted the temptation to throw his untried players in to the lion's den - although five have sufficiently impressed him to make the bench.
Front rows Carys Phillips and Bethan Howell will join back row Nia Davies on the bench while full back Dyddgu Hywel and wing Rafiuke Taylor also make the replacements.
"I'm happy with the team selection because if you look at the squad from one to 15, all the players have got some international experience behind them," said Edwards.
"It's great that we have Catrin, Gemma and Catrina back in the frame as they bring a vast amount of experience to the team. But even some of the younger players like Rosie Fletcher, who was one of the few positives to come out of last season, has got five caps to her name as has Rebecca de Filippo who is still only 18 years old," he added.
"With just one season of international rugby behind them, they have become established players in the side while the uncapped players who have made the bench are all there on merit and form.
"Ireland are getting better and better all the time and have an established line-up but going into the match we are very confident. We've definitely got the players and the right game-plan, we just have to make sure we perform on the day."
