Exelon Press Release

LONDONDERRY TWP. Pa. (May 31, 2010) – Three Mile Island Unit 1 (TMI-1) began producing carbon-free electricity today at 7:18 a.m. ET when operators connected the plant to the regional power grid. TMI-1 generates 852 megawatts of electricity, enough power for more than 800,000 homes.

The unit was taken offline on May 28 at 11 p.m. ET to perform maintenance on a reactor coolant pump. The maintenance work has been completed.

While the plant was offline, plant personnel took advantage of the opportunity to do additional maintenance to ensure a reliable summer operating run.

C&D Technologies, Inc. (C&D) received a report from a non-domestic customer who is not a U.S. licensee concerning cracks in positive post seals in C&D 3DCU-9 batteries.

The Pennsylvania Environmental Quality Board (EQB) approved two important water protection rules that will shield both drinking water and the state's rivers and streams. One rule sets a protective limit on total dissolved solid (TDS) pollution and requires Marcellus Shale drillers to treat wastewater that they discharge to rivers and streams to drinking water standards. The second rule requires new developments to create or protect a 150 foot natural filter planted with trees and other plants along our best waterways.

From the Philadelphia Inquirer:

The Nuclear Regulatory Commission has found the Department of Veterans Affairs in apparent violation of three federal regulations involving radiation use at 13 VA hospitals across the country, including the Philadelphia VA Medical Center.

While the action could result in a fine, the bigger issue is that the commission could strip the VA of its ability to oversee radiation services at all 153 hospitals nationwide. The commission would then take on those duties or assign them to states such as Pennsylvania and New Jersey that have that capability.

"We have concerns about the way oversight and enforcement actions are being implemented" by the VA, commission spokeswoman Viktoria Mitlyng said.

From the Burlington Free Press:

Vermont Yankee reported Friday afternoon that the radioactive isotope strontium has been located in the soil near where tritium had been discovered leaking at the Vernon nuclear power plant in January.

Strontium-90 was discovered in soil that had been excavated from the area of the leak, Vermont Yankee spokesman Larry Smith said. It was noted in an analysis the company received Monday from a soil sample taken March 17, he said. The state Health Department and Nuclear Regulatory Commission were notified Thursday, he said.

From the U.S. Energy Information Administration

The nuclear industry has expressed strong interest in continuing the operation of existing nuclear facilities, and no particular technical issues have been identified that would impede their continued operation. Recent AEOs had assumed that existing nuclear units would be retired after 60 years of operation (the initial 40-year license plus one 20-year license renewal). Maintaining the same assumption in AEO2010, with the projection horizon extended to 2035, would result in the retirement of more than one-third of existing U.S. nuclear capacity between 2029 and 2035. Given the uncertainty about when existing nuclear capacity actually will be retired, EIA revisited the assumption for the development of AEO2010 and modified it to allow the continued operation of all existing U.S. nuclear power plants through 2035 in the Reference case.
