Porthilly mussels are very robust, but like all bivalves they don’t particularly like a chilly fridge. If you find any that have opened when you go to use them, DON'T PANIC! Take them out of the bag, pop them in a colander and give them a really good hard shake with little splashes of water. Tim's mussels really are robust and they will close. Be quite brutal, they sometimes need a good shake about but you will see the shell start to close. As long as there's movement (even if it's very slow), they are alive and you can just throw them in the pan and enjoy
