SUPPORTIVE INFORMATION FOR THE CONTAINMENT ISOLATION SYSTEM (2.4.5) 1.
Amplifyinc Information for the CIS Amplifying information on acceptance testing for containment isolation valves and actuators is provided in CESSAR-DC Table 6.2.4-1. Containment isolation valve arrangements are presented in more detail in CESSAR-DC Figure 6.2.4-1.
l 2.
CESSAR-DC Chanter 14 Tests Annlicable to the CIS The following pre-operational tests are required of the Containment Isolation System:
Test Description CESSAR-DC Section Containment Isolation Valves (CIVs) Test 14.2.12.1.135 Containment isolation valves are tested for leakage in accordance with 10 CFR Part 50, Appendix J. This test is designed to verify that the measured leakage through each containment penetration isolation valve, when summed with the total of all other Type B and C Leak Rate Tests, is within the limits stated in the Technical Specifications. In addition, each containment isolation valve test leakage is compared against the leakage acceptance criteria for the particular valve, which is based on valve seat diameter in accordance with ASME Code OM Part 10.
Containment Isolation Valves Test 14.2.12.1.140 l
This test is designed to demonstrate that containment isolation valves can be operated manually and operate in response to automatic actuation, to verify that upon loss of actuating power the valves change position as designed, and to verify that valves operate in less than a specified time.

Relationshin of the Safety Anahsis to the CIS l
Although the safety analyses described in CESSAR-DC Chapter 15 make no direct reference to the Containment Isolation System, system function is an integral part of the SYSTEM 80+" engineered safety features described in CESSAR-DC Chapter
- 6. The Containment Isolation System provides the means ofisolating fluid systems j
that pass through containment penetrations such that any radioactivity that may be 1
released into the containment following a postulated design basis accident will be i
l confined. The safety related functions of the Containment Isolation System are fully l
described in CESSAR-DC Section 6.2.4; the safety evaluation of the system is presented in CESSAR-DC Section 6.2.43.

The PRA assumes leak tightness of electrical penetrations will be at least as good as current industry electrical penetratio:as. For all penetrations, the sealant material will be chosen to have good high temperature stability. The PRA assumes containment equipment hatch, personnel airlocks, and fuel transfer tube flange will be of the seal-under-pressure design.

Amplifyine Information for the CCWHXSVS (ADDED) 9.4.10 Component Cooling Water Heat Exchanger Structure (s) Ventilation System 9.4.10.1 Desien Basis i
The CCW Heat Exchanger Structure (s) Ventilation Systems are designed to maintain i
a suitable emironment for the operation, maintenance, and testing of equipment, and to maintain a suitable access and working environment for personnel. Each system i
consists of an exhaust fan, dampers, and unit heaters (as shown on Figure 9.4-10), that perform air exchange and heating functions.
Ec CCW Heat Exchanger Structure (s) ventilation systems are located completely within Seismic Category I structures, and all components (fans, dampers, ductwork) are fully protected from floods and tornado missile damage and interaction with other non-seismic systems. The fans, dampers, unit heaters, ductwork and supports are designed as Seismic Category II and Safety Class NNS. The outside air intake and exhaust openings are protected by missile shield walls and bird screens, and are provided with physical barriers in accordance with the guidance provided in Regulatory Guide 5.65. Air intakes are located a minimum of 20 feet above grade and away from plant discharges to minimize the ingress of dust and contaminants into the system. These design features provide a high degree of reliability, although, the ventilation system is not required for proper operation of the CCW system.
Two CCW Heat Exchanger Structure (s) ventilation systems are provided, one for each division of CCW. The two ventilation systems are separated with physical barriers. There are no interconnections between the two ventilation systems.
9.4.10.1.1 Codes and Standards Equipment, work, and materials utilized conform to the requirements and recommendations of the codes and standards listed below:
A.
Fan ratings conform to the Air Moving and Conditioning Association (AMCA) Standards.
]
B.
Fan motors conform to applicable standard of the National Electrical i
Manufacturers Association (NEMA) and the institute of Electrical and Electronic Engineers (IEEE).
C.
Ventilation ductwork conforms to applicable standards of the Sheet Metal and Air Conditioning Contractors National Association (SMACNA).

System Description
Each of the two Component Cooling Water Heat Exchanger Structure (s) Ventilation Systems consists of one vane. axial exhaust fan, with associated dampers, ductwork, i
supports and control systems.
The ventilation fans operate as required to ventilate and maintain temperature.
l Electric resistance unit heaters automatically activate to maintain ambient temperature above 40*F.
9.4.10.2.1 Component Description Each of the two CCW Heat Exchanger Structure (s) ventilation systems consists of an exhaust fan, and motor operated intake and exhaust dampers.
Unit heaters mounted on the walls consist of thermostatically controlled electric resistance heating coils and fans to heat and circulate the air.
9.4.10.2.2 System Operation During operation of the ventilation systems, outside air is drawn in through the intake damper and exhausted by fans to the outside. Air is drawn into the upper and lower floors of the structure, then collected by the exhaust ductwork and discharged to the outdoors. The unit heaters are sized to maintain minimum structure environmental conditions, taking into account transmission losses and ventilation air flow rates.

SUPPORTIVE INFORMATION FOR THE CCW HEAT EXCHANGER STRUCTURE VENTILATION SYSTEM (2.731) 1.
Amplifyine Infouation for the CCWHXSVS (Continued) 9.4.103 Safety Evaluation ne CCW Heat Exchanger Structure (s) Ventilation Systems are Safety Class NNS, and are not required to operate for the CCW system to perform its safety function.
i The CCW system has the potential to become radioactively contaminated, but the Duid is monitored by radiation detectors and is contained within the piping system, so no provisions are made by the ventilation system to contain the release of radioactive materials in the CCW Heat Exchanger Structure.
9.4.10.4 Inspection and Testine Reauirements The CCW Heat Exchanger Structure (s) Ventilation Systems operate as required to limit temperature in the heat exchanger structure and are accessible for periodic inspection.
9.4.10.5 Instrumentation Anolication Instrumentation is provided for automatic or manual operation of the system, from local or remote locations, and permits verification that the system is operating satisfactorily.
Indication of the fan operating status is provided in the control room. Failure of a running fan is alarmed in the control room.
Space temperature indication for the CCW heat exchanger structure is provided in the control room along with alarm indication of high and low temperature.
