The ISFSI well is tested annually.The groundwater table general gradient slopes downward toward the river. Water in the saturated zone under the flood plain occurs as free groundwater or in a leaky aquifer between alluvium on top and bedrock below, or both. Groundwater on the hillsides occurs under a mixture of perched conditions and in minor quantities in cracks in the rocks. The unsaturated zone on the hillsides is relatively thin. Groundwater loading conditions developed at or near grade are conservatively used for design purposes.Rains or spills on the ground surface eventually arrive at the river by overland flow or as groundwater movement at velocities from a few to several hundred feet per day. No changes since decommissioning have occurred to alter the drainage system in such a way as to create local flooding.2.4.2 Floods 2.4.2.1 Flood History.Since the current site elevation is approximately 21 ft above mean sea level (MSL), and since some means of high water protection had to be provided, knowledge of flood flows and elevations at the site was particularly important.

Table 2.4-1 gives data for historic floods from 1814 through 1984. The two greatest flows over the past 325 years occurred 30 months apart, on March 21, 1936, and September 23-24, 1938. Computed flood stages and discharges at Bodkin Rock were 28.2 and 25.75 ft MSL, and 267,000 and 239,000 cfs, respectively.

The August 1955 hurricane produced a 20.44 ft MSL flood stage and a 177,000 cfs discharge.

Since 1936, the potential for reaching similar flood levels has been decreased by the construction of a number of reservoirs in the river basin which were constructed specifically for flood control.In the years since the plant began operation, no floods have exceeded the levels of the 1936 flood at the plant site.2.4.2.2 Flood Design Considerations The ISFSI flood design considerations are contained within Reference 2.4-1. The flooding design basis is 19.5 ft. MSL.2.4.2.3 Effects of Local Intense Precipitation Average annual rainfall increases from about 38 in. in the northern part of the drainage area to about 47 in. in southern Connecticut.

Runoff averages about 60% of the total rainfall but varies seasonally and can be as low as 25% in the summer. Spring runoff may be high because of melting snow cover and heavy rains; this combination caused the 1936 flood. Reference 2.4-1 provides a detailed discussion with respect to the effects of local probable maximum precipitation and drainage characteristics for the site.1) .1 1)r )ni i HADDAM NECK PLANT UFSAR CHAPTER 3 DESIGN OF STRUCTURES, COMPONENTS, EQUIPMENT AND SYSTEMS 3.1 CONFORMANCE WITH NRC GENERAL DESIGN CRITERIA 3.1.1 Summary Discussion The General Design Criteria (GDC) for Nuclear Power Plants as listed in Appendix A to 10 CFR 50 were effective May 21, 1971 and subsequently amended July 7, 1971.There are 55 total GDCs, divided into six groups; these are intended to establish minimum requirements for the design of nuclear power plants.The full term operating license (FTOL) was issued December 27, 1974 and the provisional operating license (POL) for the Haddam Neck Plant (HNP) was issued June 30, 1967, thus the plant was designed and licensed prior to the issue of the Nuclear Regulatory Commission (NRC) GDCs. The HNP is not obligated to comply with the GDCs. The HNP was originally evaluated on a plant-specific basis, determined to be safe, and licensed by the Commission, Reference 3.1-1.However, in support of the application for a full term operating license, Reference 3.1-2, the design of the HNP was analyzed and compared with the 21 proposed August 1968 IEEE Criteria for Nuclear Power Plant Protection Systems and the 70 proposed July 1967 GDC for nuclear power plants issued by the AEC.The analysis made by Connecticut Yankee Atomic Power Company (CYAPCO) at that time (December 1969) concluded that the plant design did meet most of these criteria.In cases where the criteria were not met, it was concluded the design was such that safety of the plant was adequate.

The NRC staff stated in its July 1971 review of the analysis that the HNP conforms with the intent of the GDC proposed in July 1967, Reference 3.1-3.However, it should be noted that this comparison and conclusion is not a commitment to meet the current GDCs. Instead, the Reference 3.1-2 comparison determined the degree of compliance with the GDCs at that time.In December of 1996, CYAPCO certified to the NRC of the permanent cessation of operations of the HNP and that all of the fuel assemblies have been permanently removed from the reactor vessel and placed in the Spent Fuel Pool, Reference 1.1-1.Following this certification, CYAPCO decommissioned the HNP. As part of the process, the Systematic Evaluation Program (SEP) Topics, Reference 3.1-4, Three Mile Island Lessons Learned Items, Reference 3.1-5, the GDC, and the Regulatory Guides applicable to the HNP were assessed for their applicability to the HNP as decommissioning proceeds.

The SEP Topics, TMI Items, and Regulatory Guides applidable to the HNP are documented in Reference 3.1-6. This section reflects the applicability of the GDCs to the CY ISFSI.LBDCR #11-01 3-1 December 2011 HADDAM NECK PLANT UFSAR The GDC were not written specifically for a nuclear power plant that is permanently defueled or being decommissioned.

When the HNP was an operating plant, CYAPCO made statements in this document of conformance to only GDC 3, 19, 60, 62, 63 and 64. The remaining GDCs are either not applicable to the ISFSI, or if they are, the respective sections of this document address the degree of conformance to the intent of the criteria.

Although not committed to meet the listed GDCs, CYAPCO's conformance is summarized below.3.1.1.1 Criteria Conformance 3.1.1.1.1 Fire Protection (Criterion 3)Criterion"Structures, systems, and components important to safety shall be designed and located to minimize, consistent with other safety requirements, the probability and effect of fires and explosions.

Noncombustible and heat-resistant materials shall be used wherever practical throughout the unit, particularly in locations such as the containment and control room. Fire detection and fighting systems of appropriate capacity and capability shall be provided and designed to minimize the adverse effects of fires on structures, systems, and components important to safety. Fire fighting systems shall be designed to assure that their rupture or inadvertent operation does not significantly impair the safety capability of these structures, systems and components." Design Conformance The regulatory requirements for the Connecticut Yankee ISFSI Fire Protection Program (Reference 3.1-7) are set forth in 10 CFR 50.48(f).

In accordance with 10 CFR 50.48(f), the ISFSI Fire Protection Program shall establish the fire protection policy for the protection of structures, systems and components from fires which could cause the release or spread of radioactive materials from the time that the plant ceases operation until the plant is completely decommissioned.

This includes the personnel, procedures and equipment required to implement the program. Subject to the requirements of 10 CFR 50.48(f), the licensee may make changes to the ISFSI Fire Protection Program without prior NRC approval provided the changes do not reduce the effectiveness of fire protection for structures, systems and equipment that could result in a radiological hazard, taking into account the plant conditions and activities during decommissioning.

LBDCR #11-01 3-2 December 2011 HADDAM NECK PLANT UFSAR 3.1.1.1.2 Prevention of Criticality in Fuel Storage and Handling (Criterion 62)Criterion"Criticality in the fuel storage and handling system shall be prevented by physical systems or processes, preferably by use of geometrically safe configurations." Design Conformance The NAC MPC storage system uses geometrically safe configurations to prevent criticality as described in the NAC MPC FSAR (Reference 3.1-8).3.1.1.1.3 Monitoring Fuel and Waste Storage (Criterion 63)Criterion"Appropriate systems shall be provided in fuel storage and radioactive waste systems and associated handling areas (1) to detect conditions that may result in loss of residual heat removal capability and excessive radiation levels and (2) to initiate appropriate safety actions." Desi.qn Conformance Criterion 63, with respect to monitoring fuel, is no longer applicable to the HNP since all the Spent Fuel have been removed from the Spent Fuel Pool and transferred to the ISFSI.lSFSI radiation levels are periodically measured as described in ISFSI RP procedures.

LBDCR #11 -0 1 8-1 December 2011 HADDAM NECK PLANT UFSAR 11.3 GASEOUS WASTE MANAGEMENT SYSTEM Radioactive gases are no longer generated at the HNP since the cessation of power operations.

At this time all spent fuel has been removed from the reactor and spent fuel pool and is maintained in storage at the Independent Spent Fuel Storage Installation (ISFSI). Therefore the Gaseous Waste Management System is no longer required.

All gaseous radioactive waste systems have been classified as Abandoned and have been decommissioned.

Their components have been removed and disposed.

Therefore, no residual radioactive noble gas is available for release at the site.11.4 SOLID WASTE MANAGEMENT SYSTEM The function of the solid waste program is to receive, package, collect and store radioactive wastes that result from ISFSI operation, maintenance and decommissioning activities.

With the completion of plant decommissioning and the storage of spent fuel and GTCC waste at the ISFSI, there is only a small potential to generate radiological material that will have to be managed as radioactive waste until decommissioning of the ISFSI. If it becomes necessary to process radioactive waste, then all applicable regulatory commitments will be met using programmatic controls and licensed contractors for handling, shipping and disposal.The estimated volumes and the activities and isotopic contents of solid wastes are given in Reference 11.2-1, the Annual Radioactive Effluent and Waste Disposal Report.The ISFSI contains selected equipment and storage capacities which meet the ISFSI solid waste processing requirements.

Three canisters of Greater Than Class C (GTCC) radioactive waste in three concrete casks are stored on the ISFSI pad.11.4.2.1 Handling of Spent Resins -Deleted 11.4.2.2 Handling of Dry Solid Wastes Contaminated DAW and metallic materials are placed into suitable transport packages, for storage and transport to a waste processor and/or disposal.

Equipment too large to be handled in this way are first cut into small pieces before placement in the packages.LBDCR #11-01 11-2 December 2011 HADDAM NECK PLANT UFSAR 11.4.2.3 GTCC Waste Storage The GTCC waste is stored in three stainless steel canisters which have been evacuated of water, filled with helium and welded shut. Each canister is stored within a concrete cask on the ISFSI pad. The GTCC waste is stored in accordance with 10 CFR 30.11.5 PROCESS AND EFFLUENT RADIOLOGICAL MONITORING
