Did Bletchley Park use the deciphered traffic "to intercept and destroy Hitler's U-Boats"?

On the whole no, they used it primarily to make sure that convoys went around the areas where the U-Boats were waiting.

Later in the in the war the information from Bletchley Park was shared with the US and both the Royal Navy and US Navy sank all the German refueling vessels for U-Boats.

The Germans never believed that the ciphers had been broken, but that copies of the codebooks had been obtained and every time they got suspicious they changed the codes that were used.

If you are interested in this area, then I recommend "Enigma" by Hugh Sebag-Montefiore, who had a special interest in Bletchley Park as it was his families ancestral home.
