Subject:

Crystal River Unit 3 - 2014 Annual Radioactive Effluent Release Report

Dear Sir:

Duke Energy Florida, Inc., hereby provides the 2014 Radioactive Effluent Release Report for Crystal River Unit 3 (CR-3) in accordance with 10 CFR 50.36a(a)(2) and the CR-3 Improved Technical Specifications (ITS), Section 5.7.1.1(c). The attached report includes a summary of the quantities of radioactive liquid and gaseous effluents, and solid waste released from the CR-3 site during 2014. The material provided is consistent with the objectives outlined in the Off-Site Dose Calculation Manual (ODCM) and the Process Control Program (PCP), and is in conformance with 10 CFR 50, Appendix I, Section IV.B.1.

The CR-3 ITS, Section 5.6.2.3, requires submittal of licensee initiated changes to the ODCM as part of the Radioactive Effluent Release Report for the period of the report in which any changes were made. The ODCM and the PCP were not revised in 2014.

No new regulatory commitments are made in this letter If you have any questions regarding this submittal, please contact Mr. Phil Rose, Lead Engineer, Nuclear Regulatory Affairs, at (352) 563-4883.

Sincerely, Blair P. Wunderly Plant Manager Crystal River Nuclear Plant BPW/ff

The plant remains shutdown in mode 7 (defueled) for all of 2010, 2011, 2012, 2013, and 2014 due to reactor building containment concrete wall delamination issues.

Due to the decision to decommission the plant, the facility will remain permanently defueled.

Unplanned Releases There were no unplanned releases in 2014.

Radioactive Waste Treatment Systems There were no significant changes to the radioactive waste treatment systems in 2014. Due to the lengthy shutdown of Crystal River Unit 3, liquid waste volume and radioactivity concentration had continued to decrease until the decision to retire CR3 and begin decommissioning was made in February of 2013. As part of the preparation to place the unit in SAFSTOR, liquid waste inventory of all systems no longer required to support spent fuel cooling have been processed and discharged as liquid wastes, where possible. The liquid waste demineralizers were recharged with new condensate resin that was previously loaded into the condensate demineralizers to support the plant restart from the refuel 16 outage. This resin is a 2:1 cation to anion macroporous gel mixture of Ambersep 200H cation resin and IRN78 anion resin. This resin has performed extremely well while processing higher activity waste tanks including reactor coolant and borated refueling water. The liquid waste processing demineralizers and filters were sluiced and recharged several times to support processing the large volume of water as systems are drained and abandoned to support reaching the SAFSTOR configuration.

Annual Land Use Census The 2014 land-use census did not identify any new dose calculation locations.

Effluent Monitor Instrument Operability For the year 2014 the main gaseous effluent pathway is the auxiliary building ventilation exhaust system.

Radiation monitor RM-A2N is the effluent monitor for this pathway. This monitor remains in service and has two back up compensatory monitors RM-A4 and RM-A8, which sample various locations of the auxiliary building. There were no Reactor Building Purge evolutions performed in 2014.

The liquid effluent pathways are the primary plant liquid waste stream, which is monitored by radiation monitor RM-L2, and the secondary plant liquid waste stream, which is monitored by radiation monitor RM-L7. These liquid radiation monitors remain operable.

As system abandonment continues so the plant can reach the prescribed SAFSTOR configuration, various radiation monitors are also being removed from service as they no longer can perform their design function due to they either have no radioactive source term to monitor or the system they originally were designed to monitor is no longer in service. The monitors taken out of service are as follows:

(Liquids)

" RM-L1, Reactor Coolant Letdown monitor

" RM-L3, Nuclear Services Closed Cycle Cooling monitor

Meterology Instrumentation Evaluation During 2014 the yearly instrumentation data recovery for all meterology tower instruments has remained in the range of > or = 95.7%. The 2014 lower level joint frequency distribution MET data recovery rate was 98.4% based on review of OSI PI data by Murray and Trettel. Actual meterological tower data is available and is maintained at the Crystal River site. The actual meterological data is not provided in this report as is allowed by the ODCM.

Offsite Dose Calculation Manual (ODCM) Changes The ODCM was not revised in 2014 or 2013. A major change to the ODCM is planned for 2015 which will support various system abandonments as the facility is configured for SAFSTOR.

Process Control Program (PCP) Changes The PCP was not revised in 2014.

Emergency Feed Pump 2 & Steam Releases Due to the fact that the plant has not operated since September of 2009, the emergency feed pump has not operated, nor has there been any secondary plant steam releases that need to be evaluated for radioactive constituents.

Based on the decision to retire and decommission CR-3, the emergency feed pump 2 will never operate again and there will be no steam releases.

Carbon-14 Evaluation During the entire year of 2014, Crystal River Unit 3 has been in a cold shutdown, defueled mode. The plant was taken off line in September of 2009 for refueling outage 16. In 2009, the primary plant was degassed, the reactor building was purged of radioactivity, waste gas decay tanks were released, a construction opening was made in the side of the reactor building containment wall, and both once through steam generators were replaced. Since the plant has been in cold shutdown for the entire years of 2010 through 2014 due to reactor building containment wall concrete delamination issues, there is no source term generation for carbon-14 production. Since the decision to retire the facility has been announced, there will be no C-14 source term generated ever again at CR-3.

Nuclear Electric Institute (NEI) Required Information The following environmental data is being included in this report per objective 2.4.b.i and 2.4.b.ii of NEI 07-07 Industry Ground Water Protection Initiative, as this groundwater well data is used to assist in evaluation of groundwater at the site, but is not officially included in the Radiological Environmental Monitoring Program (REMP) or the Offsite Dose Calculation Manual (ODCM). These 2 graphs are of tritium measurements in units of pCi/I, taken from groundwater monitoring wells located west of CR-3 on either side (north and south) of the site settling ponds. There are many other groundwater monitoring wells included in the REMP that are used for evaluating the groundwater in the vicinity of the CR-3 site.

These 2 wells are providing supplemental information. The LLD for tritium measurement of these environmental well samples is -150 pCi/I.

Additional Information On February 5, 2013, Duke Energy announced that a decision has been made to permanently retire Crystal River Unit 3. The decision was made due to the high cost of repair and risk associated with repairing the containment building's delaminated concrete wall. The company is working to develop a comprehensive decommissioning plan and intends to place the facility in SAFSTOR for the immediate future and eventual dismantling. The plant staff (called decommissioning transition organization) is working to shutdown and abandon as many systems as possible, by removing energy sources, lubrications, greases, electrical, and system fluids to prepare the unit for SAFSTOR and eventual dismantlement.
