HADDAM NECK PLANT UFSAR CHAPTER 2
.) . ~:SITE CHARACTERISTICS This chapter contains information on the geological, seismological, hydrological and meteorological characteristics of the site and vicinity, in conjunction with population distribution, land use and site activities and control. The purpose of this section was to indicate how these site characteristics influenced plant design, operation and decommissioning and show the adequacy of the site characteristics from a safety viewpoint. However, much of the information that was presented in this chapter is historical in nature and, as permitted by R.G. 1.181 (Reference 2.1-4), this information does not require updating. Therefore, in order to eliminate confusion between the historical information and information that needs to be maintained as
- ~---,part of the plant's "design basis", sections 2.1.3, 2.3, 2.4, and 2.5 have been annotated to indicate that the information contained in these sections is 'Historical Information Only".
2.1 GEOGRAPHY AND DEMOGRAPHY 2.1.1 Site Location and Description 2.1.1.1 Specification of Location The site is located in the Town of Haddam, Middlesex County, Connecticut, on the east bank of
--the Connecticut River at a point 21 miles south-southeast of Hartford, Connecticut, and 25 miles northeast of New Haven, Connecticut. Figure 2.1-1 shows the site location.
The geographical coordinates of the centerline of the reactor were as follows:
Latitude Northing
"-,,.and LonQitude and Eastinc N410 28'57" N236, 589 W720 29'57" E668, 745 The general plant area was filled and graded from an initial elevation of approximately 12 ft mean sea level (MSL) to a final elevation of 21 ft. This grade is 1.5 ft above the highest recorded river level near the site. At the back or east side of the plant, wooded hillsides rise steeply above the perpendicular rock cut, while the Connecticut River acts as a barrier on the west side as well as at the southern end of the peninsula, approximately one mile from the plant. Access to the site is gained over an improved access road from the north. The general topography is shown on Figure 2.1-2.
2.1.1.2 Site Area Map The site consists of approximately 525 acres, bounded by the property lines as shown on Figure 2.1-3. The minimum distance overland from the reactor containment to the exclusion area as defined in 10 CFR 100.3, shall be 1,740 ft and the distance to the nearest residence is over 2,000 ft. The largest nearby city, Middletown, is 8 air miles northwest of the plant.
LBDCR #37 2.1-1 November 2004
HADDAM NECK PLANT UFSAR The location and orientation of the plant structures within the site area at the time of permanent Yj shutdown are shown on the Site'Plot Plan, Figure 2.1-4.
Decommissioning changes to thelplant involving structures other than the fuel building, Independent Sperit Fuel Storage Installation (ISFSI) or auxiliary equipment building are not
- - considered a change to the facility as described in the UFSAR.' As such, Figure 2.1-4 may not
! reflect the up-to-date configuration of site'structures as the plant progresses through decommissioning.
2.1.1.3 : Boundaries for Establishing Efflubnt Release Lirmits Figure 2.1:3 depicts the property line and site boundary line. The property line is that line
-beyond which land is not owned;'Jeased or otherwise controlled. The area within the site boundary is governed by the HNP Part 50 License (Reference 2.1-10 and 2.1-11).
The land outside the bounds of the site boundary is considered an unrestricted area for
'--:' *-rbdiation
-';:- protection purposes. The land areas between the site boundary and the security protected area is generally considered a controlled area, access to which can be limited by the L;Y 2; ' iliceiisee-.i'Restricted areas are areas which are limited by the licensee for the purposes of protection of individuals from exposure to radiation and radioactive materials. The Haddam
' NeckPlant restri6ted area ah'd industrial protected area geneially correspond. Additional restricted'areas ma~y be designated by the licensee in the controlled area as necessary to
protect individuals against exposure'to radiation and radioactive materials. The ISFSI is a restricted area. The restricted areas, the controlled area, and the unrestricted area are shown
":-,'on Figuire 2.1-3. - 1
- The Haddam Neck Plant prepares an Annual Radioactive Effluent and Release Report (Reference'2.1-1) that provides actual plant effluent release data.
2.1i2-
- Exclusion Area Authority and Control 2.1.2.1 Authority
-The1H-ddarn Ndck Plant is owned by the Connecticut Yankee Atomic Power Company (CYAPCO):;.Along the river bank' the exclusion area'extends to the opposite shore (westeml
-side)'of the Connecticut River. The minimum distance to the boundary of the exclusion area, as
' defined in:10'CFR 100.3, shall be .1740 feet from the reactor'containment. Connecticut Yankee
' 'AtomicPower Company has the controlling authority to determine all activities within land
' portion"of-the exclusion area. In a letter dated April 29, 2004, a written request was submitted to the NRC of intent to release the East Side Grounds (Survey Area 9532) from the Part 50
- license (Reference 2.1-10). The NRC approved that request on September 1, 2004 (Reference 2.1-11). The site area is reduced as a result of the release of the non-impacted area from the
' Part 50 Li6&nse-(i.e;,i-sobne portion of the exclusion area will be outside the site boundary).
Figure 2.1-3 shows the new site boundary.. Since CYAPCO still owns the property covered by
- -thisrees6 area (Survey area 9532) CYAPCO will continue to maintain authority, in accordance with 10'CFR 100.3, over the activities conducted beyond thelsite boundary (i.e.,
over the activities conducted within 1740 feet of the Reactor Containment until such time as the reanalysis shows the exclusion area can be reduced or eliminated).
Y' i Arrangements with the U.S. Coast Guard and the State of Connecticut allow for closure of river traffic, if necessary, during an emergency (Reference 2.1-2).
LBDCR #37 2.1-2 November 2004
HADDAM NECK PLANT UFSAR 2.1.2.2 Control of Activities Unrelated to Plant Operation No part of the site is leased and all structures located on the site are under the control the Connecticut Yankee Atomic Power Company.
The location and extent of the plant site was one of the considerations entering into the analysis of the overall safety of the plant.

HADDAM NECK PLANT UFSAR The population distribution within 10 miles of the plant is based on 1990 Census of Population by Census Block (Reference 2.1-7). The population within each Census Block was assumed to K be'distributed evenly over its land area, unless shown other'wise by USGS 7.5 minute quadrangle maps (Reference 2.1-9) of the area. The proportionof each Census Block area within each grid sector was estimated and applied to the total population within the Block. The population' of all Blocks or portions bf Blocks within a sector were'added to calculate the total population within each sector.; Populatiorn projections by municipality, generated by the Connecticut Office of Policy'and Management (Reference 2.1-6), provided growth factors to
-:calculate the population in each sector in the future.

HADDAM NECK PLANT UFSAR 3.8 DESIGN OF CLASS I AND CLASS II STRUCTURES K<>' With the decision to decommission the Haddam Neck Plant the only remaining safety related structures are those associated with the spent fuel island. As a result, this chapter has been modified to address those safety or regulatory functions that are still served by these and other plant structures.
3.8.1 Containment Structure Due to decommissioning, the functions of the containment structure have changed from those of an operating plant. The containment structure presently serves the following purposes:
- 1. The containment shell serves as a barrier to the release of airborne activity from ongoing work.
- 2. A portion of the containment interior structure serves as an extension of the fuel transfer tube.
- 3. A portion of the containment shell serves as a seismic support for the yard crane.
- 4. A portion of the containment shell serves as a seismic support for the fuel transfer tube.
All greater than Class C (GTCC) waste was transferred from containment to the spent fuel pool and the flange on the fuel transfer tube was sealed to form the spent fuel pool boundary.
3.8.2 Auxiliary Structures 3.8.2.1 Spent Fuel Building K> The Spent Fuel Building, shown on Figure 3.8-2, is of concrete construction to elevation 47 with an insulated Galbestos superstructure on steel framing above the spent fuel pool area. The roof of the spent fuel building truck bay, at elevation 47 and the roof of the spent fuel area at elevation 76, are both of concrete construction.
A cask handling area is provided in the building for NAC-MPC canister handling and loading activities. The area consists of a concrete pad which extends out of the east side of the building to allow loadingfunloading of fuel transfer components to the heavy haul trailer.
Air is provided locally by an air compressor. Water is provided by the makeup water system only.
