submitted an application to the United States

for a 20-year extension of the existing 40-year license for Oyster Creek, which was due to expire in 2009. According to a 2006 survey commissioned by the operators, relicensing of the power plant was supported by the majority of citizens living in areas surrounding the plant, and by local elected officials. However, some local opposition to re-licensing was evident at public hearings on the issue. On May 31, 2007, several Ocean County residents attended the Atomic Safety Licensing Board (ASLB) hearing in the county administration building. At that meeting, several of the local residents were opposed to re-licensing of the nuclear power plant. The ASLB's decision on May 31, 2007 hearing led to a full public hearing on the issue of the monitoring of corrosion in the plant's drywell liner. The hearing was scheduled for September 24, 2007 in the county seat Toms River. In 2008, the Atomic Safety and Licensing Board twice rejected citizens' contentions concerning Oyster Creek. The majority of the three-judge panel ruled in favor of the plant, deciding "that the group's motion did not follow the proper guidelines for late-filed contentions and failed to link an alleged inadequacy to a significant safety issue." In May 2007, the state Attorney General's Office, on behalf of the state Department of Environmental Protection (NJDEP), petitioned the federal Third Circuit Court of Appeals to compel the Nuclear Regulatory Commission to consider the potential for a terrorist attack as part of the criteria for Oyster Creek's licensing renewal process. In July 2007, the NJDEP faulted both Exelon and the Nuclear Regulatory Commission for relying on environmental studies that were up to 30 years old at the time of Exelon's relicensing application. The NJDEP refused to make a "positive consistency determination" for Oyster Creek, as required by the federal

. The positive determination is required for all applicants seeking to relicense an existing facility. On April 8, 2009 the plant was granted a license extension to operate until April 9, 2029. This came a week after the Nuclear Regulatory Commission voted 3–1 against an appeal by anti-nuclear groups. As of June 2009, five environmental and citizen groups were appealing the decision in the federal court. Richard Webster, attorney for the groups, claims the NRC did not have sufficient information to determine whether the plant can operate safely for the next 20 years. “This has been the most extensive license renewal review to date, including the first adjudicatory hearing of a license renewal application,” said Eric Leeds, NRC's director of Nuclear Reactor Regulation. “The staff’s licensing and inspection scrutiny, along with the independent contributions of the ACRS, the ASLB and various citizen groups, should give the people of New Jersey added confidence that Oyster Creek will remain safe during its continued operation.”

Closure and decommissioning

In December 2010, Exelon reported that Oyster Creek would close in 2019, 10 years earlier than planned so that cooling towers will not have to be installed to meet new environmental standards. In February 2018 the closure date was adjusted to October 2018. The reactor was ultimately shut down on September 17, 2018, and its fuel was removed by September 25, 2018. Work will now begin on dismantlement and long-term decommissioning. Oyster Creek was sold to Holtec International in July 2019 after clearing regulatory approval, and a Holtec and

joint venture called Comprehensive Decommissioning International will be responsible for decommissioning the plant. About 200 of Oyster Creek's employees will remain at the plant to carry out decommissioning work with Holtec.

Electricity Production

Environment

As a part of Exelon Corporation, Oyster Creek followed the corporation's environmental policy. In August 2009, workers found and stopped two small leaks of

of about 12 years. An NRC investigation of the leak found that the levels were too low to be a danger to public health. The leaks originated from two buried pipes that had not been properly insulated when they were last worked on in 1991. A second leak was discovered in August 2009, from a pipe leading into an electrical turbine building. Tritium levels found in this leak were measured at 10 microcuries per liter of water, higher than the 5 to 6 microcuries per liter found in the earlier leak. Tritium-contaminated groundwater remained on site and had not spread to any public water supplies. In May 2010, the New Jersey DEP announced that water from the leak had spread to a nearby aquifer, though it stated there "was no imminent danger" to water supplies. At the current rate of migration, the water will reach the closest public wells within 10 to 15 years. The DEP stated there are several ways to address the problem, such as pumping out the tainted water, or injecting fresh water to force the tainted water backwards. A spokesman for Oyster Creek said they are working with the state on the issue, and have seen contamination levels steadily dropping, sometimes by "as much as 90%". Tritium causes less concern than other radioactive substances such as strontium, caesium and iodine. It does not bio-accumulate inside human tissue.

Safety

Employees at the Oyster Creek nuclear power plant averaged less radiation exposure from 2005 through 2008 than workers at any other nuclear power plant of similar design in the United States. In early May 2011, fuel supplier General Electric notified the operators of the Oyster Creek and Nine Mile Point nuclear plants regarding safety calculation errors. General Electric had made mathematical errors which could have resulted in nuclear fuel getting hotter than operators expected, reducing the plants' margin of safety. Plant operators were able to make corrections.

Hurricane Sandy

, the nuclear power plant's intake structure was flooded with six and a half feet of water as a result of the storm surge from the hurricane, with no damage sustained, and at the same time the plant was already down for maintenance and lost its electrical power from the grid, so operators called an alert that escalated the plant a step up from the lowest emergency level, and turned to backup generators to keep cooling the reactor. In following months, local residents continued to voice their worries despite a statement by Gordon K. Hunegs of the Nuclear Regulatory Commission that during Hurricane Sandy "the plant was always safe."

Seismic risk

The Nuclear Regulatory Commission's estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at Oyster Creek was 1 in 71,429, according to an NRC study published in August 2010.
