The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of amendments to Renewed Facility Operating License Nos. DPR-31 and DPR-41, issued to Florida Power and Light Company, for operation of the Turkey Point Nuclear Power Plant, Units 3 and 4, located in Miami-Dade County, Florida. Therefore, as required by 10 CFR 51.21, the NRC is issuing this environmental assessment and finding of no significant impact.
Identification of the Proposed Action
The proposed action would increase the number of fuel assemblies that can be stored at each unit at Turkey Point from 1,404 fuel assemblies to 1,535 fuel assemblies, an increase of 131. A freestanding spent fuel storage rack module would be installed in the cask pit in each unit's spent fuel pool. In addition, the new spent fuel storage racks will use Boral as a neutron absorbing material.
The proposed action is in accordance with the licensee's application for amendment dated November 26, 2002, as supplemented in a letter dated September 8, 2003.
The Need for the Proposed Action
The Turkey Point Nuclear Plant, Units 3 and 4, has two pressurized-water reactors. Unit 3 commenced operation in 1972 and Unit 4 in 1973. Based on the current licensed capacity, current spent fuel inventory, and the projected discharges of spent fuel, Unit 3 will lose the capability to fully offload the reactor core by the year 2007. Unit 4 will lose the capability to fully offload the reactor core by the year 2009. To extend this capability beyond the above dates, the licensee has proposed license amendments to install a freestanding spent fuel storage rack module in the cask pit of each unit's fuel handling building. The spent fuel pool for each unit is currently licensed to store a total of 1,404 fuel assemblies in high-density racks using Boraflex neutron absorbing panels. The new racks will use Boral as the neutron absorbing material. The racks are designed for storage of 131 fuel assemblies, increasing the total storage capacity of each unit to 1,535 assemblies.
The additional storage capacity provided by the cask pit racks will be used to store spent fuel to allow refueling outage fuel offloads and non-outage fuel shuffles. The cask pit racks will be removed, cleaned, and stored in an alternate location prior to any spent fuel cask loading operations.
Environmental Impacts of the Proposed Action
The NRC has completed its evaluation of the proposed action and concludes, as set forth below, that there are no significant environmental impacts associated with the proposed amendment. The details of the staff's safety evaluation will be provided in the license amendment when it is issued by the NRC.
During refueling outages, there may be a slight increase in the amount of heat that has to be removed from the combination of the spent fuel pool and the cask pit. The peak increase will be less than one percent, and the heat load from spent fuel storage is very small compared to the heat load from normal plant operations. Therefore, the overall increase in the amount of heat released will be quite small and insignificant.
Even though additional boron will be introduced by the Boral panels in the storage racks in the cask pit, no significant increase in tritium production from the neutron capture by boron-10 is expected.
The proposed action will not significantly increase the probability or consequences of accidents, there are no significant changes in the types or significant increase in the quantities of effluents that may be released offsite, and there is no significant increase in occupational or public radiation exposure.
With regard to potential non-radiological impacts, the proposed action does not have a potential to affect any historic sites. It does not affect non-radiological plant effluents and has no other environmental impacts. Therefore, there are no significant non-radiological environmental impacts associated with the proposed action.
Accordingly, the NRC concludes that there are no significant environmental impacts associated with the proposed action.
Environmental Impacts of the Alternatives to the Proposed Action
As an alternative to the proposed action, the staff considered denial of the proposed action (i.e., the “no-action” alternative). Denial of the application would result in no change in current environmental impacts. The environmental impacts of the proposed action and the alternative action are similar.
Alternative Use of Resources
The action does not involve the use of any different resources than those previously considered in the Final Environmental Statement related to operation of Turkey Point Plant, dated July 1972, and Supplement 5 to NUREG-1437, “Generic Environmental Impact Statement for License Renewal of Nuclear Plants Regarding Turkey Point Units 3 and 4,” dated January 2002.
Agencies and Persons Consulted
On September 29, 2003, the staff consulted with Michael Stevens of the Bureau of Radiological Control regarding the environmental impact of the proposed action. The State official had no comments.
Finding of No Significant Impact
On the basis of the environmental assessment, the NRC concludes that the proposed action will not have a significant effect on the quality of the human environment. Accordingly, the NRC has determined not to prepare an environmental impact statement for the proposed action.
