2.2.3 Deleted 2.2.4 Heat Exchanger The residual heat exchanger of the Auxiliary Coolant System was originally sized for the mal cooldown of the RCS. Table 6.2-7 gives the design parameters of the heat exchanger.
The residual heat exchanger is a conventional vertical shell and U-tube type unit. The tubes seal welded to the tube sheet. The shell connections are flanged to facilitate shell removal for ection and cleaning of the tube bundle. The unit has a SA-285 Grade C carbon steel shell, a
-234 carbon steel shell end cap, SA-213 TP-304 stainless steel tubes, SA-240 Type 304 nless steel channel head, SA-240 Type 304 stainless steel channel head cover and SA-240 e 304 stainless steel tube sheet.
The ASME Boiler and Pressure Vessel Code has strict rules regarding the wall thickness of pressure containing parts, material quality assurance provisions, weld joint design, ographic and liquid penetrant examination of materials and joints, and hydrostatic testing of unit, as well as requiring final inspection and stamping of the vessel by an ASME Code ector.
The design of the heat exchanger also conforms to the requirements of TEMA (Tubular hanger Manufacturers Association) for Class R heat exchangers. Class R is the most rugged s of TEMA heat exchangers and is intended for units where safety and durability are required er severe service conditions. Items such as: tube spacing, flange design, nozzle location, baffle kness and spacing, and impingement plate requirements are set forth by TEMA Standards.
In addition to the above, additional design and inspection requirements were imposed to ure a rugged, high-quality heat exchanger such as: confined-type gaskets, main flange studs h two nuts on each end to ensure permanent leak tightness, general construction and mounting kets suitable for the plants original seismic design requirements, tubes and tube sheet capable withstanding full shell side pressure and temperature with atmospheric pressure on the tube

All parts of the valves originally designed for use in the SI System in contact with borated er are austenitic stainless steel or equivalent corrosion resistant material.
Valving was specified for exceptional tightness and, where possible, such as instrument es, packless diaphragm valves were used. All valves, except those, which perform a control ction, were originally designed with backseats, which were capable of limiting leakage to less 1.0 cc per hour per inch of stem diameter, assuming no credit taken for valve packing.
2.2.6 Deleted 2.2.7 Manual Valves The stainless steel manual globe, gate and check valves installed as part of the original plant struction were designed and built in accordance with the following requirements. The pressure taining parts (body, bonnet and discs) of the valves were designed, in the earlier editions of ME III, per criteria established by the USAS B16.5 or MSS SP66 specifications. The current ME III refers to a large extent to ANSI B16.34 for valve requirements. The materials of struction for these parts are procured per ASTM A182, F316 or A351, GR CF8M, or CF8. All erial in contact with the primary fluid, except the packing, is austenitic stainless steel or ivalent corrosion-resisting material.
The carbon steel valves are built to conform with USAS B16.5. The materials of struction of the body, bonnet and disc conform to the requirements of ASTM A105 Grade II, 1 Grade II or A216 Grade WCB or WCC. The carbon steel valves pass only non-radioactive ds and are subjected to hydrostatic test as outlined in MSS SP-61 except that the test pressure aintained for at least 30 minutes. Since the fluid controlled by the carbon steel valves is not oactive, the double packing and seal weld provisions are not provided.
2.2.8 Deleted 2.2.9 Deleted 2.2.10 Deleted 2.2.11 Piping All SI System piping in contact with borated water is austenitic stainless steel. Piping joints welded.

h as the non-destructive testing requirements of Nuclear Code Case N-7.
Minimum wall thicknesses are determined by the USAS Code formula in the power piping tion 1 of the USAS Code for Pressure Piping. This minimum thickness is increased in ordance with plant engineering specifications to account for manufacturing tolerances and d allowances. Purchased pipe and fittings have a specified nominal wall thickness that is no than the sum of that required for pressure containment, mechanical strength, and ufacturing tolerance.
Pipe and fitting materials were procured in conformance with all requirements of the ASTM USAS specifications. All materials were verified for conformance to specification and umented by certification of compliance to ASTM material requirements. Specifications ose additional quality control upon the suppliers of pipes and fittings as listed below.

DELETED DELETED DELETED DELETED DELETED DELETED 1 Design Basis 1.1 Containment Heat Removal Systems Adequate heat removal capability for the containment is provided by the Containment Air ling System whose components operate as described in Section 6.3.2.
The Containment Air Cooling System was originally designed to cool the containment osphere in the event of a design basis loss-of-coolant or main steam line break accident.
KPS has permanently ceased operation. Therefore, the Containment Air Cooling System is operated, as needed, to maintain the containment environment suitable for personnel access the long term SAFSTOR of the station. Containment Air Cooling no longer has a containment sure limiting/reducing function.
1.2 Deleted 1.3 Deleted 1.4 Deleted 1.5 Deleted 2 System Design and Operation A schematic arrangement of the Containment Air Cooling System is shown in Figure 5.4-1.
Individual system components and their supports meet the requirement for Class I*
smic) structures.
2.1 Containment Air Cooling System Characteristics The Containment Air Cooling System consists of a fan-coil unit, a duct distribution system, emergency discharge dampers and the associated instrumentation and controls.
The fan-coil unit is located in a missile-protected area outside of the primary compartments.
The fan-coil unit consists of helical-fin cooling coil, housing, fan and motor.
The vane-axial fan is driven by a single-speed motor originally designed to be capable of vering the horsepower required to move the required quantity of air-steam mixture under
ditions following a loss-of-coolant accident.
Ducts distribute the cooled air to the various containment compartments and areas. The mal sequence through the fan coil unit is as follows: cooling coil, vane-axial fan, distribution t header and emergency discharge dampers.
The heat sink for the fan coil unit is provided by the Service Water System.
In removing heat at the design rate, the fan coil ducting and emergency discharge dampers capable of discharging the resulting condensate without impairing the flow capacity of the 2.2 Actuation Provisions The fan coil unit has a flow rate capacity of 44,000 cfm under normal conditions.
Overload protection for the fan motor is provided by an overcurrent trip device. The breaker the fan motor can be operated manually from the control room.
The motor of the fan coil unit is rated 125 hp. Short circuit and overload protection is vided in the feeder breaker for the motor.
Resistance Temperature Detectors (RTDs) are located in the ductwork, including one nstream of the Containment Fan Coil Unit. Temperature indicators and temperature alarms provided in the control room.
2.3 Flow Distribution and Flow Characteristics The duct distribution system is designed to promote good mixing of the containment air and ures that the recirculated cooled air will reach all areas. The distribution system is represented ematically in Figure 5.4-1.
The system includes a ring header and branch ducts to the primary compartments for ribution of cooled air from the fan-coil discharge. The cooled air is circulated upward from the er primary compartments, through the steam generator compartments to the operating floor l.
The fan-coil unit has an emergency discharge damper (permanently failed open) installed s discharge duct at the operating floor level. The damper is opened to ensure cooled airflow mixing of the containment air. The ring header also discharges air to the containment area ve the operating floor level. Air that has risen to the top of the containment dome is drawn n toward the suction of the fan-coil units by the Containment Dome Ventilation System fans.
Containment Dome Ventilation fan draws air from the highest point in the center of
dome) downward to the operating floor inside containment, where the air is then discharged.
The temperature of the air returning to the fan-coil unit will be essentially the ambient ting in the Reactor Containment Vessel.
2.4 Cooling Water for the Fan-Coil Unit The cooling water requirements for the four-fan coil unit is supplied by the service water ps. The Service Water System is described in Chapter 9.
The fan-coil unit is supplied by the service water header outside the containment as shown igure 9.6-4. The piping to and from the fan-coil unit contains adequate valving to allow the coil unit to be isolated for maintenance.
The cooling water discharge from the fan-coil unit is monitored for radioactivity by routing mall bypass flow through a radiation monitor. Upon indication of radioactivity in the effluent, fan-coil unit discharge line is monitored and isolated as necessary.
Flow indication is provided outside containment for service water to the fan coil unit. A ure in a service water header will be detected by containment sump level instrumentation. The nitude of the leak is estimated using the containment sump level change with time. Leaks of ter magnitude can be detected by sequentially isolating each header discharge and comparing flow rate through each header. Leaks of smaller magnitude are detected by isolating each der sequentially and trending Containment level versus time.
The fan-coil unit and the Service Water supply are operated as necessary to control tainment temperature.
2.5 Deleted 2.6 Component 2.6.1 Fan-Motor Unit The Containment Air Cooling System fan is of the vane-axial, non-overloading, direct drive The fan is driven by a totally enclosed 125-horsepower, induction type, 3-phase, 60-Hertz,
-V, 1200 rpm, Reliance Electric Motor. Significant motor details are as follows:
Insulation
Nomex and Kapton. Wedges are of a silicone glass laminate and separators are of a Kapton or silicone glass laminate. Power supply leads are insulated with materials suitable for the pre-decommissioning design basis accident conditions.
Bearings The motor has anti-friction ball bearings for both the thrust and radial bearings. Bearings are lubricated with a special high temperature, radiation-resistant grease.
Conduit (Connection) Box The motor leads are brought out of the frame through a seal and into an oversized conduit box. The seal material is suitable for both the temperature and radiation conditions experienced following the pre-decommissioning design basis loss-of-coolant accident.
2.6.2 Cooling Coils The cooling coil contained within the Containment Fan Coil Unit was replaced in 1992. The was not N stamped which allowed installation and maintenance consistent with current tice.
The Containment Fan Coil Unit's replacement coil was procured so that the thermal ormance was equivalent or better than the existing CFCU coil. The replacement coil utilizes a cal fin construction and is slightly more efficient in terms of heat removing capability than the inal coil.
The replacement coil was required to be the same weight or less to maintain the current mic documentation for the CFC Unit.
Two key improvements were instituted in the design of the coil to delay the effects of ion; the tube wall thickness was increased at the return bends from 0.049" to 0.085" (average) the tube material was changed to a harder 70-30 Ni-Cu material.
In addition the coil was fabricated under the requirements of ASME Division I Class 3 ch is an enhancement over the original fabrication.
The heat removal capability of the replacement fan coil is 54.8E+6 Btu/hr when entering m air mixture is at 270°F. Air and water flow paths are arranged for counter flow.
The coil is provided with drain pan and drain piping to prevent flooding. This condensate is ned to the containment sump.
2.6.4 Fan-Coil Emergency Discharge Dampers The dampers are parallel blade, pneumatically operated (air open, spring close) type.
Isolation dampers are provided to prevent back flow through an inactive unit.
All ductwork, damper blades, and seating surfaces are constructed of, or coated with osion-resistant materials.
2.6.5 Electrical Supply Details of the power sources are presented in Chapter 8.
Further information on the components of the Containment Air Cooling System is given in pter 5.

Their descriptions follow. Radiation monitoring capabilities that remain part of station design are described in Chapter 11.

This instrumentation has the characteristic of being sensitive to water vapor within containment. Plots of containment air dew point variations above a base-line maximum blished by the cooling water temperature to the air coolers should be sensitive to incremental age equivalent to 2 to 10 gpm.
The sensitivity of this method depends on cooling water temperature, containment air perature variation, and containment air recirculation rate.
1.2.5 Containment Sump Leakage Measuring System This leak detection method is based on the principle that the leakage collected by the tainment sump will be pumped to the waste holdup tank, with pumping time directly related to quantity of leakage. Sump pump running time is monitored in the control room, and will vide an indication of deviation from normal leakage rates to the operator.
m primary coolant leaks is directed to the containment sump. The difference between the ume of leakage within Containment Sump A at the high level alarm setpoint and the volume of age within Containment Sump A at the sump pump auto shutdown setpoint is used for rmining leakage rates into the sump. This known volume, divided by the time it takes for age into Sump A to refill the sump to its high level alarm setpoint indicates the average age into the sump during the time period under consideration. Detection of leakage rates ter than 10 gpm are possible within 30 to 40 minutes. Larger leakage rates are detectable in ch shorter time periods. Leak rates of less than 0.5 gpm can be detected by this method.
A break in the reactor pressure vessel or the service water lines within the abandoned tainment enclosure would result in water flowing into the containment sump. Leakage to this p would be indicated by the frequency and duration of operation of the containment sump ps.
