Service returns to Pilgrim as questions linger

Pilgrim Nuclear Power Station in Plymouth returned to service Wednesday following its seventh outage or other unexpected problem in two years, prompting critics to question whether there are larger issues at the plant.

The plant was shut down Monday after workers found a leak in a safety valve; earlier in January Pilgrim went offline for six days when recirculation pumps used to adjust power levels stopped working.
