WSES-FSAR-UNIT-3 3.2-1 Revision 14 (12/05)
(DRN 05-127, R14) 3.2 CLASSIFICATION OF STRUCTURES, COMPONENTS AND SYSTEMS
(DRN 05-127, R14) 3.2.1 SEISMIC CLASSIFICATION In compliance with General Design Criterion 2, plant structures, systems and components which are important to safety are designed to remain functional in the event of a safe shutdown earthquake (SSE) if they are necessary to assure:
a) the integrity of the reactor coolant pressure-boundary, b) the capability to shutdown the reactor and maintain it in a safe shutdown condition, or
(DRN 05-127, R14) c)
the capability to prevent or mitigate the consequences of accidents which could result in potential offsite exposures comparable to the guideline exposure of 10CFR50.67.
(DRN 05-127, R14)
(DRN 03-291, R12-B)
Plant structures, systems and components, including their foundations and supports, that are designed to remain functional in the event of a safe shutdown earthquake are designated as seismic Category I, as indicated in Table 3.2-1. The seismic classifications are consistent with the recommendations of Regulatory Guide 1.29, "Seismic Design Classification", August 1973, with a clarification noted in Table 3.2-1 for the reactor coolant pump bearing oil, cooling systems and refueling water storage pool.
(DRN 03-291, R12-B)
For systems which are partially seismic Category I, the seismic Category I portion includes all components within the seismic boundary and extends to the first seismic restraint beyond the boundary.
All seismic Category I structures, systems and components are analyzed under the loading conditions discussed in Section 3.7.
Non-seismic structures, systems and components are those whose failure would not result in the release of significant radioactivity and would not prevent reactor shutdown or degrade the.operation of Engineered Safety Feature Systems. Their failure may, however, interrupt power generation.
The occurrence of adverse interaction between safety and non-safety related components during SSE events are eliminated by adherence to the following:
a)
Whenever practical, the safety related components are separated from the non-safety related components to ensure that failure of the nonsafety related component due to a SSE will not result in loss of function to the safety related components.
b)
In those areas where adequate separation is not possible, the nonsafety related components are provided with seismic supports, or barriers are provided between the safety related and non-safety related components.
Where only portions of systems are identified as seismic Category I, the boundaries of the seismic Category I portions of the system are shown on the piping and instrument diagrams in appropriate sections of this FSAR.
WSES-FSAR-UNIT-3 3.2-2 Revision 14-A (03/06) 3.2.2 SYSTEM SAFETY CLASSIFICATIONS Table 3.2-1 specifies the safety class for those plant structures, systems and components that have a safety function. System safety classifications and interfaces between classifications in systems with components of different classifications are indicated on the system piping and instrument diagrams in appropriate sections of this FSAR.
System components important to safety and the containment boundary are classified in accordance with ANSI N18.2, "Nuclear Safety Criteria for the Design of Stationary Pressurized Water Reactor Plants",
1973, and ANSI N18.2a, "Revision and Addendum to Nuclear Safety Criteria for the Design of Stationary Pressurized Water Reactor Plants", 1975 as clarified by Table 3.2-1. The relationship between safety classes 1,2,3 and non-nuclear safety (NNS) and NRC quality group classes A,B,C and D is as follows:
Waterford 3 Safety Class Regulatory Guide 1.26 Quality Group Safety Class 1 A
Safety Class 2 B
Safety Class 3*
C NNS (Non-Nuclear Safety)
D System safety classifications and design and fabrication requirements meet the intent of Regulatory Guide 1.26, "Quality Group Classifications and Standards for Water-, Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants", June 1975, with a clarification noted in Table 3.2-1 for the reactor coolant pump bearing oil and cooling systems. Table 3.2-2 separately lists equipment from Table 3.2-1 which are not designed and built to the exact ASME Code specified in Regulatory 1.26.
For original installations, the existing configuration provided for instrument air tubing and components of safety-related valve top assemblies shall either meet all RG 1.26 Quality Group C requirements; or meet the material requirements for ASME Section III Class 2 with exception of the hydrostatic testing and the Authorized Nuclear Inspection, be installed per ANSI B 31.1, and be supported with Seismic Class 1 tubing supports.
(DRN 05-1637, R14-A)
Future installations, including replacements, of instrument air tubing and components of safety-related valve top assemblies shall utilize components that satisfy all Division 1 construction requirements as defined in ASME Code Section III Subarticle NCA-1110 Article NCA-9000 and Subsection ND, excepting that 1) the design may be based on the rules of ANSI B31.1 with the tubing supports designed as Seismic Class 1, and 2) the tubing and components may be exempted from the Authorized Nuclear Inspection requirement and 3) components not available to meet the ASME Code Section III and for which ASME Code Section III rules are not intended to be applicable (NCA-1130), such as valve operators, controllers, position indicators, or other accessories and devices may meet original design requirements, including ANSI B31.1, seismic qualification, and 10CFR50 Appendix B program compliance.
(DRN 05-1637, R14-A) 3.2.2.1 Safety Class Interfaces For Fluid Systems Unless separated by suitable barriers, interconnected components which fit different safety class definitions are of the higher classification.
A passive barrier (e.g., heat exchanger tubing) that separates safety classes serves as the required barrier between classes but is categorized in the higher class. No additional barrier is provided between the barrier and components of the lower safety class. Otherwise, barriers are supplied in one of the following combinations where components of differing classes are interconnected. The higher class extends to and includes the cited barriers.
WSES-FSAR-UNIT-3 3.2-3 Revision 10 (10/99)
Any safety class to a lower safety class:
a)
One safety valve.
b)
Two normally open valves in series if active failure of a single valve combined with failure of any lower class component could prevent a system safety function of the higher class system or result in uncontrollable release to the environment of gaseous activity normally held up.
Safety class 1 to all lower safety class:
a)
One passive* or two active** flow restricting devices. An exception is the leakoff from the reactor coolant pump seal system where the interconnection between safety class 1 and unclassified components (safety class 3 outside containment) contains two seals in series and the leakoff to the waste disposal system contains no isolation valving.
b)
Two normally closed valves in series.
Safety class 2 or 3 to a lower safety class:
a)
One normally closed valve.
b)
One normally open valve if its active failure combined with passive failure of any lower class component could not prevent achievement of the minimum safety system function of the higher class system or result in controllable release to the environment of gaseous activity normally held up.
c)
No valves are necessary if failure of the lower class components will not result in loss of safety function of the higher class component or uncontrollable release to the environment of gaseous activity normally held up. An example is an unclassified vent line on a safety class 2 or 3 atmospheric storage tank, failure of which will not result in loss of fluid from the tank.
The closure time for each normally open valve, used as an interface boundary, is such that for any postulated failure of a lower safety class component outside the interface boundary, the safety system function of the higher safety class system is maintained and orderly reactor shutdown is not prevented.
For a check valve to qualify as the safety class 1 interface boundary, it must be located inside the containment.
The CEDM Cooling Coil and the CCW Radiation Monitors are classified NNS, seismic Category 1. The safety class interface isolation valves in the CCW supply and return lines are normally open. All piping between the interface valves and the CEDM Cooling Coil and CCW Radiation Monitors is Safety Class 3, seismic Category I.
- Examples are controlled leakage shaft seals, or orifices or connected small components where failure of any lower class component would not prevent orderly shutdown.
- Example is excess flow valve which includes a restricting bypass.
WSES-FSAR-UNIT-3 3.2-4 Revision 11 (5/01)
(DRN 99-0820) 3.2.3 CODES FOR SAFETY CLASS COMPONENTS 3.2.3.1 Original Construction Codes The original construction codes used for the materials, design, fabrication, inspection, and testing of structures, components, and systems are as specified in applicable sections of the FSAR.
3.2.3.2 Codes for Repairs and Replacements Repairs and replacements of structures, components, and systems are performed in accordance with the original construction codes. However, later editions are addenda of the original codes are used as allowed by 10CFR50.55a and as described below:
3.2.3.2.1 For ASME Section XI repairs and replacements, later editions and addenda of the original codes may be used as allowed by ASME Section XI.
3.2.3.2.2 For welder and procedure qualifications later editions and addenda of ASME Section IX may be used as specified in engineering specifications.
3.2.3.2.3 For repairs and replacements to ASME Section VIII pressure vessels and ANSI B31.1 piping systems, later editions and addenda of these codes may be used as specified in engineering specifications.
3.2.3.2.4 For structural steel, sheet steel, and sheet metal welding, later editions of the AWS welding codes may be used a specified in engineering specifications.

(DRN 03-633, R12-C)
- 2.
Loss of cooling water to the reactor coolant pump motors caused by a failure of the non-seismic category (Quality Group D) motor bearing oil systems or the air coolers may prevent normal continuous operation of the pumps. However, continuous operation of the pumps is not required during or following a SSE because they do not serve a safety function. Therefore, the specific recommendations of Regulatory Guides 1.26 and 1.29 are not applied to these pump auxiliaries.
- 3.
These components and associated supporting structures must be designed to retain structural integrity during and after a seismic event but do not have to retain operability for protection of public safety. The basic requirement is prevention of structural collapse and damage to equipment and structures required for protection of public safety.

Piping and Valves - Piping and valves between seismic Category 1 equipment, components or tanks shall be Category 1. Piping shall be Category 1 up to and including the barrrier (as defined in Subsection 3.2.2.3) in the line from a Category 1 component to a non-seismic component. Reactor coolant pressure boundary (RCPB) is defined in 10CFR 50.2
- 6.
Components which are connected to the RCS and are part of the RCPB are classified as Safety Class 2 provided:
a)
In the event of postulated failure of the component during normal reactor operation, the reactor can be shut down and cooled down in the orderly manner, assuming makeup is provided by Chemical and Volume Control System only, or (DRN 03-633, R12-C) b)
The component is or can be isolated from the RCS by two valves (both closed, both open, or one closed and the other open). Each open valve must be capable of automatic actuation and assuming the other valve is open, its closure time must be such that, in the event of postulated failure of the component during normal reactor operation, each valve remains operable and the reactor can be shut down and cooled down in an orderly manner, assuming makeup is provided by the Chemical and Volume Control System only.
(DRN 03-633, R12-C)
- 7.
Instrumentation - Instrumentation required to actuate, maintain operation of, or detect failure of equipment needed to safely shut down, isolate and maintain the reactor in a safe condition and prevent uncontrolled release of radioactivity from the station shall be Class 1E/seismic Category I. Instrumentation designated as Class 1E/seismic Category I shall include as Class 1E/Category I all sensing lines, instrument valves and instrumentation racks. All Class 1E/Category I instrumentation will receive applicable 10CFR50 Appendix B QA during the operations phase.

The Main Steam and Feedwater lines are seismic Category 1 up to the system of restraints at column line G as shown on Drawing G134.
(DRN 03-633, R12-C)
- 10.
For safety-related components which are not covered by ASME Section III, the design of the component is in accordance with other recognized industry codes or standards applicable to that of component. The quality assurance program applied to the design, manufacture, installation, testing and operation of the component meets the applicable requirements of the facility QA program.
(DRN 03-633, R12-C)
- 11.
This is an outdated Safety Classification (i.e., Safety Class 2). Regulatory Guide 1.7 (April 1974) no longer requires the purge system to be redundant or be designated seismic Category I, except insofar as portions of the system constitute part of the primary containment boundary.
(DRN 03-633, R12-C;06-870, R15)
- 12.
Electrical Equipment - All cables, relays, motors, switchgear and other electrical equipment serving safety system components required to function during the SSE shall be Class 1E, if they are necessary for the performance of the component's safety function. All Class 1E electrical equipment will receive applicable portions of 10CFR50 Appendix B QA during the operations phase.

Although all cabling for the CET's is qualified to Class 1E criteria, some of the cabling is run in NNS cable trays, see Appendix 1.9A for details.
- 23.
The canal, pools, and their liners are classified as structures and are therefore not assigned a safety class, but are designed and constructed as seismic Category I under the 10CFR50 Appendix B requirements. The liners and their nozzles are constructed to ASME Section VIII code requirements using ASME Section III materials.
- 24.
Pressure switches PS-HV-5222 AS and BS function only to alarm on a loss of instrument air. This alarm function will not be lost as a result of a failure of the associated tubing. Therefore, the signal process tubing for these switches has been classified non-safety.

The Refueling Water Storage Pool (RWSP) is designed in accordance with the recommendations of Regulatory Guide 1.29 Seismic Design Classification with exception to footnote 1. Regulatory Guide 1.29 recommends the system boundary include portions of the system required to accomplish the specified safety function and connected piping up to and including the first valve that is either normally closed or capable of automatic closure when the safety function is required. The RWSP purification system is non-safety and connected to the RWSP by normally open, manual isolation valves. Operator actions may be required to isolate the purification system from the RWSP (Reference Operating License Amendment No. 186 in ER-W3-1999-3544-001).
