From Enformable Nuclear News:

After the Fukushima nuclear disaster, the health effects of ionized radiation have become a hot topic around the globe.  A new study showing that survivors of the Hiroshima and Nagasaki nuclear bombings have continued to show a higher-than-normal risk of thyroid cancer, over half a century after their initial exposures.

The researchers calculated that 36 percent of the 191 thyroid cancers that eventually developed in people who were kids or teens at the time of the attacks were likely due to radiation exposure.

“Thyroid cancer is one of the most radiosensitive cancers,” said Dr. Kiyohiko Mabuchi of the National Cancer Institute in Bethesda, Maryland, who worked on the new study.

On February 28, 2012, PPL filed a Notice of Intent with the PUC to increase  “distribution rates and will allow the Company to begin to recover the costs incurred since 2010 for the improvement and expansion of its distribution system. The request also will reflect increases in operation and maintenance costs since 2010, including costs associated with major storm events, programs to enhance retail electric competition and customer education.”

June 19, 2012 – Operators at the Unit 1 reactor performed a planned shutdown to investigate the source of a minor water leak inside the containment structure.

A plant official said the leak does not affect the safety of the plant or the public. Unit 2 is continuing to operate at full power.

May 7, 2012 – The NRC issued a report dealing with a supplemental inspection at the Unit 1 reactor from Feb. 13 through March 2, 2012. The inspection stemmed from unplanned scrams (plant shutdowns) in 2010 and early 2011, and an internal flooding incident in the third quarter of 2010 that resulted in a white finding from the NRC of low to moderate safety significance.

From Bellona:

The reactor vessel is one of the most important safety elements, both holding hot water under pressure and preventing the escape of radionuclides into the environment. Theoretically, should Dael No 3’s vessel be damaged, a cement barrier surrounding it would prevent further spread of radionuclides. (Lampert emphasis)

Possible problems with the vessel were first suspected by FANC in June, it said on its website statement. The agency has also promised to publicize a dossier of its data confirming that the cracks “do not threaten the structural integrity of the reactor vessel,” suggesting that the regulator is attempting to justify the reactor’s further use.
