Behind layers of security and a thick concrete wall, a team of welders work in shifts to fix the crippled Penly nuclear plant in northern France. Sweating under protective gear, they’re replacing cracked pipes in the emergency cooling system which protects against a reactor meltdown.
Each weld takes at least three days to complete, with workers often on their knees or backs to reach for the correct angle. Even in radiation suits, health regulations limit work in that environment to a maximum 40 hours a year.
The complicated procedures, replicated across sites this winter, have hampered the ability of Electricite de France to get its reactors back online after lengthy shutdowns.
