Subject:

Oyster Creek Nuclear Generating Station Independent Spent Fuel Storage Installation Annual Report

Reference:

Building Permit; Appeal 93-40 (after remand)

Conditions 10 and 11 of the referenced building permit require the Oyster Creek Nuclear Generating Station (OCNGS) to submit annual reports to Lacey Township concerning the status and operation of the OCNGS Independent Spent Fuel Storage Installation (ISFSI).

Enclosure 1 provides the OCNGS response to Conditions 1O and 11. Enclosure 2 provides the ISFSI 2016 monthly average temperature graphs and Enclosure 3 provides the most recent ISFSI 2016 seml-annual radiation survey.

If any further information or assistance is needed, please contact Rheiner Dutes at {609) 971-4629.

Sincerely,

}

Enclosure 1 Oyster Creek Nuclear Generating Station Independent Spent Fuel Storage Installation Response to Building Permit Conditions 10 and 11 Independent Spent Fuel Storage Installation (ISFSI)

Building Permit Condition Ten:

"The applicant shall provide to the township on a yearly basis, written records revealing all temperature and radiation measurements. The applicant shall further advise of any and al!il reparrs made to- Ehe- COl"l'Crete modufes."'

Oyster Creek Nuclear Generating Station (OCNGS) Reply to Condition Ten:

The temperatures within the loaded concrete Horizontal Storage Modules (HSMs) are monitored daily and are part of the stations surveillance records. The average internal temperature of the loaded HSMs is approximately 84°F and the average internal temperature of the unloaded HSMs is approximately 61°F. The average internal temperature of the loaded HSMs is approximately 8° to 33°F higher than unloaded HSMs, depending on the heat load of the spent fuel loaded in the HSM. Between October 31, 2015 and October 31, 2016 the highest HSM temperature measurement was approximately 125°F. This is well within the design limits of the modules and represents a maximum aCtual heat loading of approximately 12 KW.

The graphs in Enclosure 2 provide the average daily temperature data for the period from October 31, 2015 to October 31, 2016, for the following HSMs.

HSM numbers Year loaded 1, 2, 3, 4 2002 5,6, 7,8 2003 9, 10, 11 2004 12, 13, 14, 15, 16. 2005 17, 18,20 2010 19,21,22,23 2012 24,25,26,27 2016 28 throuqh 34 Empty

. areas between HSMs) are 1.6 mr/hr gamma (i.e. vented region between HSM-15 and HSM-17) and 1.0 mrem/hr neutron (i.e. on HSM-18 and HSM-22). These readings are well within the design limits of the modules. The most recent semi-annual radiation survey is provided as Enclosure 3.

There were no repairs performed to the concrete HSMs or Independent Spent Fuel Storage Installation (ISFSI) in the last year. The total number of installed HSMs remains the same as the number in the previous annual report. No additional HSMs were

• installed since 2012. Four additional HSMs were loaded with spent fuel in the 2016 ISFSI campaign during the spring.

Enclosure 1 Oyster Creek Nuclear Generating Station Independent Spent Fuel Storage Installation Response to Building Permit Conditions 10 and 11 The existing OCNGS ISFSI, which was reviewed under Building Permit, Appeal 93-40 (after remand) is complete with 34 installed HSMs, of which 27 are loaded with spent fuel.

• ISFSI Building Permit Condition Eleven:

"The applicant shall provide to the township on a yearly basis, the specific number of spent fuel rod assemblies which have been moved into the dry storage facility."

OCNGS Reply to Condition Eleven:

The following table provides the number of fuel assemblies that were transferred to the ISFSI for each of the applicable years, starting in 2002. There were no fuel assemblies loaded into the ISFSI prior to 2002. Presently, there are no further transfers planned until 2018; however, rescheduling may occur given plant status and future activities.

Year loaded Number of assemblies 2002 244 2003 244 2004 183 2005 - -

305 2010 183 2012 244 2013 0 2014 0 2015 0 2016 244 Total assemblies 1647 Status of Yucca Mountain Repository The Department of Energy (DOE) submitted a license application for construction of the Yucca Mountain Repository to the Nuclear Regulatory Commission on June 3, 2008.

In testimony to the Senate Budget Committee on March 11, 2009, Dr. Steven Chu, DOE Secretary, stated "[B]oth the President and I have made clear that Yucca Mountain is not a workable option." In accordance with this view, the Administration requested, and Congress appropriated, for FY201 O, only enough funds to continue the NRG license proceeding, while halting any design or development progress on the actual repository.

The Administration's FY2011 budget proposal eliminated all funding for the Yucca Mountain project.

Enclosure 1 Oyster Creek Nuclear Generating Station Independent Spent Fuel Storage Installation Response to Building Permit Conditions 10 and 11 Shortly before releasing the FY2011 budget proposal, the Administration directed the DOE to establish a Blue Ribbon Commission on America's Nuclear Future (Commission) to explore, study, and evaluate alternatives to the Yucca Mountain facility for the permanent storage of spent nuclear fuel. The Commission's goal was to "provide recommendations for developing a safe, long-term solution to managing the nation's used nuclear fuel and nuclear waste." The Commission would not, however, consider specific sites for a future repository. The Commission was charged with producing an interim report within 18 months of the Commission's establishment and a final report within 24 months.

The Commission issued its final report on January 26, 2012. The report did not make any specific recommendations as to the "suitability" of Yucca Mountain, other than to make clear that the process of selecting and establishing the Yucca Mountain facility has suffered from several flaws and should be replaced by a new "consent-based approach" that provides "incentives" and encourages interested communities to "volunteer" as a potential host site for an eventual repository.

While acknowledging that "the future of the Yucca Mountain project remains uncertain,"

the Commission did make specific findings that may have significant influence over the future of nuclear waste disposal. The Commission concluded that deep geologic disposal "is the most promising and accepted method [of disposal] currently available,"

and therefore recommended that the United States "should undertake an integrated nuclear waste management program that leads to the timely development of one or more permanent deep geological facilities for the safe disposal of spent fuel and high-level nuclear waste." The Commission also reiterated the severe consequences of continued delays and urged Congress and the President to take action to institute the Commission's recommendations "without further delay." Congress has thus far taken no action to implement the Commission's recommendations.
