General Information 3.0 PROGRAM DEVELOPMENT ASME OM Code-2004 (hereafter referred to as 'the OM Code!) requires that the owner of each nuclear power plant prepare and submit a "plan" for testing and inspection of systems and components under the jurisdiction of the Code and in compliance with Title 10, Part 50 of the Code of Federal Regulations (Para. 50.55a).

Inservice Testing of ASME Class 1, 2, and 3 pumps and valves is performed in accordance with the OM Code 1 OF 14

Constellation Energy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 2004 Edition, except as allowed by 10CFR50 or where specific written relief has been granted by the NRC pursuant to 10CFR50.55a(f)(6)(i) for examinations and tests determined to be impracticable. Provided guidance of NUREG 1482, Revision 1, is followed, the proposed alternative examinations or tests may be implemented prior to receiving written NRC approval if so stated in the guidance document.

The OM Code, Subsections ISTA and ISTB shall be utilized for the inservice testing of pumps. Subsections ISTA and ISTC shall be utilized for the inservice testing of valves. Subsection ISTA, ISTC and Appendix I shall be utilized for the inservice testing of pressure relief devices. Appendix II, Check Valve Condition Monitoring, may be utilized for certain check valves within the IST Program scope. The OM Code of Record for the Fourth 10-Year Interval has not been approved for use in 10CFR50.55a(b)(3). This is addressed in program relief request GA-RR-01.

ASME OM Code Cases that have been approved for use by the NRC per Regulatory Guide 1.192 and are adopted for use at Calvert Cliffs are identified in the IST Program. The following Code Cases shall be used during the Fourth 10-Year Interval IST Program implementation with all conditions, as applicable:

OMN-1, "Alternative Rules for Preservice and Inservice Testing of Certain Electric Motor-Operated Valve Assemblies in Light-Water Reactor Power Plants," Revision 0 (upon approval of Relief Request GV-RR-02)

OMN-8, "Alternative Rules for Preservice and Inservice Testing of Power-Operated Valves That Are Used for System Control and Have a Safety Function per OM-10," Revision 0 (upon approval of Relief Request GV-RR-03)

In accordance with the Code and 10CFR50.55a, the following are required to be included in the testing Program:

ASME Class 1, 2, or 3 centrifugal and positive displacement pumps that are provided with an emergency power source and are required to perform a specific function in

1) Shutting down the reactor to the safe shutdown condition;

2) Maintaining the safe shutdown condition; or

3) Mitigating the consequences of an accident.

ASME Class 1, 2 and 3 active or passive valves (and their actuating and position indicating systems) which are required to perform a specific function in

1) Shutting down the reactor to the safe shutdown condition;

2) Maintaining the safe shutdown condition; or

3) Mitigating the consequences of an accident.

ASME Class 1, 2 and 3 pressure relief devices that protect systems or portions of systems which perform a required function in

1) Shutting down the reactor to the safe shutdown condition;

2) Maintaining the safe shutdown condition; or

3) Mitigating the consequences of an accident.

In addition to the general Code requirements outlined above, there are other interpretations and positions that have come about as a result of past regulatory and licensee actions including NUREG-1482.

The term "accident" refers not only to the design basis accidents analyzed in Chapter 14 of the UFSAR, but to a broad range of possible adverse events which could affect plant safety. Additional accidents and operational transients, and the equipment required to mitigate the possible consequences thereof, are identified in the UFSAR.

The CCNPP safety analysis specifically requires the units to reach a safe-shutdown condition defined as hot standby and not the cold shutdown condition. Per NUREG-1482, Revision 1, pumps and valves in such plants 2 OF 14

Constellation Energy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 needed only to reach cold shutdown need not be included in the Inservice Testing Program. However, in some instances, CCNPP has decided to include cold shutdown-related components in the Program for completeness even though compliance with Code requirements may not be required.

In light of the foregoing, a set of rules was established by which the scope of the CCNPP ASME OM Code IST Program is determined including components that are to be included and the extent and type of testing required for each component. Based on these rules, the philosophy and assumptions used in determining the test requirements for selected pumps and valves were documented.

3.1 Initial Program Scope Inthe course of validating the Program scope for the fourth interval, each of the significant safety systems (included within the ISI-class boundaries) were evaluated with respect to the function of each component and the need for its operability as it relates to the scope of the OM Code. Supporting documents used include, Updated Final Safety Analysis Report (UFSAR);

Technical Specifications; Past program correspondence; and Operating Procedures (Normal, Emergency and Off-Normal).

The sequence followed during the review effort was as follows:

1) Each of the plant systems was subjected to an overview to determine any potential safety function as described in the scope statement. Those systems with no safety functions were then excluded from further consideration.

2) For the remaining systems, flow diagrams were studied and any components that could possibly have an active or passive safety function were identified for further evaluation.

3) The function of each component was determined. This included classifying valves and their functions as passive or active. Testing requirements were then derived based on the component function(s) and the applicable rule(s).

4) Documents were reviewed and specific or implied component operational requirements were compared to the information derived in 3, above.

5) The results of Steps 1 through 4, above, were reviewed by several knowledgeable members of the plant staff and evaluated for accuracy and consistency. Based on this review, the final program scope was derived and the IST Program Plan updated.

3.2 Program Update During the fourth 10-year interval, it is expected that the scope of the Program will occasionally be modified in response to activities including, but not limited to:

1) Plant design changes;

2) Changes in operating conditions (e.g. normal valve lineup);

3) Changes in accident mitigating procedures philosophy; or

4) Regulatory demands.

As a result, the IST Program will be revised to ensure continued compliance with the Code requirements relating to the scope of the test program, as necessary.

The supervisor responsible for maintaining the IST Program is provided input from Engineering regarding plant modifications that are designated by Engineering to have a potential IST/ISI impact. Additionally, other pertinent changes such as a significant change in plant operating or accident mitigation philosophy that might have a direct impact on the IST Program are also reviewed. Should a change require a Program revision, the IST Coordinator implements the change to the Program Plan and the appropriate test procedure(s) in a timely manner.

3.3 Program Scope Philosophy The final scope of the Fourth Ten-Year Interval IST Program was determined based on an exhaustive search and comprehensive evaluation of numerous design-basis and licensing-basis documents which included, in part, the 3 OF 14

Constellation Energy (CCNPP Unit 1) IST Program PUMP AND VAL VE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev O00 CCNPP UFSAR and Technical Specifications, various engineering and 0-List evaluations, various CCNPP Operating Procedures and Instructions, various CCNPP Abnormal and Emergency Operating Procedures, and numerous related NRC Generic Letters, Safety Evaluation Reports, and other current and historical docketed pieces of BGE-NRC correspondence.

The purpose of this effort was to identify and evaluate the safety function(s) of all potential candidate pumps and valves. The major criteria for including pumps and valves in the IST Program may be generalized/summarized as follows:

1. Pumps and valves credited in CCNPP UFSAR Chapter 14 Accident Analyses for accomplishing, or supporting, one or more of the Critical Safety Functions: Reactivity Control, RCS Pressure & Inventory Control, RCS Heat Removal, Containment Isolation & Environment, Radiation Control, and Vital Auxiliaries.

2. Selected pumps and valves which provide "operational flexibility," i.e. components which are not specifically credited but may be substituted for components which are credited as accomplishing or supporting the Critical Safety Functions,

3. Selected pumps and valves which support implementing selected "alternate success paths" (which are not credited) for accomplishing necessary safety functions, (However, uncontrolled scope growth would dilute Program effectiveness ifadditional testing did not provide additional safety benefits. To avoid this, CCNPP considered factors such as (1) the number of other "success paths" and which ones were already included in the IST Program, (2)the scope of other preventive maintenance or testing programs, (3) available equipment redundancy versus applicable single failure requirements, e.g.

multiple failure scenarios are generally not included in the IST Program scope. Additionally, there are several ways CCNPP can progress from the licensed safe shutdown condition to the cold shutdown condition. However, since CCNPP is licensed for a safe, vice cold, shutdown condition, not all these components are necessarily classified safety-related and/or ASME Code Class 1, 2, or 3.)

4. Pumps and valves for which specific commitments have been made regarding inclusion in the IST Program,

5. Pumps and valves whose inclusion in the IST Program is specifically required by CCNPP Technical Specifications,

6. Selected pumps and valves whose assumed performance is considered critical in applicable, pertinent, engineering evaluations/calculations,

7. Pressure relief devices which met the above criteria themselves, or protect systems/portions of systems which met the above criteria.

3.4 Skid-Mounted Components Code class systems may include skid-mounted components or component subassemblies. A skid-mounted component is one that is integral to, or that supports operation, of a major component. These components are usually procured as part of a larger component assembly and are often not designed to meet the requirements for components in ASME classes 1, 2, and 3. A component that functionally meets this description may be treated as "skid-mounted" even if it is not located directly on the skid of the major component. Often the "major" component is not subject to 10 CFR 50.55a and inservice testing requirements because only specific components/subcomponents are ASME Code Class 1, 2, or 3. However, the major component is typically subject to other testing requirements. As defined in Subsection ISTA-2000 and specifically addressed in Subsections ISTB-1200(c) and ISTC-1200, skid-mounted components may be excluded from the specific applicable OM testing requirements provided that their operational readiness is verified when the major component is tested and justified by the owner to be adequately tested. In NUREG-1482, Rev. 1, Section 3.4, the NRC Staff has determined that the testing of the major component is an acceptable means for verifying the operational readiness of skid-mounted components and component subassemblies provided this approach is discussed in the IST Program document.

Most air-operated control valves at Calvert Cliffs have an associated solenoid valve that supports the control valve's operation. Each solenoid valve associated with a control valve is considered to be a skid-mounted component/component subassembly and is not separately listed in the Valve Tables. These solenoid valves make up the bulk of the skid-mounted components/component subassemblies included in the Calvert Cliffs 4 OF 14

Constellation Energy (CCNPP Unit 1) IST Program PUMP AND VAL VE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 IST Program. The manner in which each air-operated control valve is tested is adequate to ensure the operational readiness of the control valve and the associated solenoid valve.

3.5 Augmented Testing Program The reviews performed to prepare the Fourth Ten-Year Interval IST Program identified some safety-related pumps and valves that do not fall within the mandatory scope of Calvert Cliffs' IST Program even though they may be used to accomplish or support significant safety functions. However, even though these pumps and valves do not fall within the required scope of the IST Program, some perform significant safety functions which would otherwise fall within the scope of the Code and, therefore, require some type of testing commensurate with their importance to safety.

Augmented testing refers to voluntary testing of components that are not within the mandatory IST scope, but are similar (in configuration and/or function) to components that are. Per NUREG-1482, Revision 1, Section 2.2, the testing of selected pumps and valves that are not legally required to be included in the IST Program can be consolidated with the IST Program tothe maximum extent desired and/or practical for convenience, without actually including them in the scope of the mandatory IST Program. These pumps and valves are tested commensurate with their safety function. To minimize confusion, augmented testing generally follows the Code to the maximum extent practical. However, augmented testing is not required to comply with the Code and "deviations" from the Code for such components do not require an approved relief request.

These pumps and valves have been integrated into the IST Program Plan, as discussed in NUREG-1482, Revision 1, so that all related testing could be grouped and tracked considering any similar components. This was done in this manner solely for Calvert Cliffs' convenience in order to minimize confusion and improve efficiency while implementing this "Augmented Testing Program" alongside the IST Program. Furthermore, to minimize confusion, Calvert Cliffs included cold shutdown and refueling outage justifications for these components to maintain consistency and clearly identify the basis for any apparent deviations from the Code. Augmented components are clearly identified as such in the IST Program Plan tables.

The bulk of these components, although not all, fall into three general categories:

ASME/ISI Classification vs. Safety Classification The scope statements in the OM Code do not specifically limit themselves to ASME/ISI Code Class 1,11,& III pumps and valves. In fact, some documents claim the Code Committee did not intend to limit the scope to only such components. However, the requirement to implement and maintain an IST Program comes from 10 CFR 50.55a and Calvert Cliffs' Technical Specification 5.5.8, which are specifically limited to ASME/ISI Code Class 1,11,

&III components. Therefore, the mandatory scope of Calvert Cliffs' IST Program is limited to ASME/ISI Code Class 1,11,& III pumps and valves. Per NUREG-1482, Revision 1, Section 2.2, non-Code Class pumps and valves are not required to be included in the IST Program. However, despite this, some of the safety functions they perform would otherwise fall within the scope of the Code and, therefore, these valves should be subject to some type of testing commensurate with their importance to safety.

Safe Shutdown Licensed Condition vs. Cold Shutdown Condition Calvert Cliffs' safety analyses specifically require the Units to reach a safe-shutdown condition defined as hot standby and not the cold shutdown condition as required by the Code. Per NUREG-1482, Revision 1, pumps and valves in such plants needed only to reach cold shutdown need not be included in the Inservice Testing Program.

Despite the fact that certain editions of the Code refer to the "cold shutdown" condition, the mandatory scope of Calvert Cliffs' IST Program is generally based on the "safe shutdown" condition that is actually specified in the plant's licensing basis. In some instances, testing of selected components needed to safely and reliably progress from the safe shutdown condition to the cold shutdown condition have been consolidated into the IST Program for completeness even though compliance with Code requirements may not be required.

Defense-in-Depth 5 OF 14

Constellation Energy (CCNPP Unit 1) IST Program PUMP AND VAL VE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 In some cases, the single failure requirements inherent in Calvert Cliffs' Technical Specifications restrict the use of certain pumps and valves for meeting system/header operability requirements. However, the use-of these pumps and valves is often included in Emergency Operating Procedures to provide alternative success paths ifthey are available. Additionally, the ability of some of these components to accomplish these functions has also been factored into Calvert Cliffs' PRA model. Therefore, many of these components are considered to contribute to Calvert Cliffs' philosophy of defense-in-depth and the testing of selected components have been consolidated into the IST Program for completeness even though compliance with Code requirements may not be required.

6 OF 14

Constellation Energy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 Pump Information 4.0 INSERVICE TESTING PROGRAM FOR PUMPS 4.1 Code Compliance The iST Program for pumps meets the requirements of Subsections ISTA and ISTB of the OM Code and any applicable interpretations or clarifications of existing requirements. Paragraph and table references in this section refer to specific paragraphs and tables in the OM Code. Where these requirements have been determined to be impractical, an alternative test provides an acceptable level of quality and safety, or conformance would cause unreasonable hardship without any compensating increase in safety, relief from Code requirements is/was requested pursuant to the requirements of 10CFR 50.55a(f)(5)(iii), 10CFR50.55a(a)3(i) or 10CFR50.55a(a)3(ii).

4.2 Allowable Ranges of Test Quantities The allowable ranges for test parameters as specified in the OM Code, Tables ISTB-5121-1, ISTB-5221 -1 and ISTB-5321 -1 will be used for all measurements of pressure, flow, and vibration except as provided for in specific relief requests.

4.3 Testing Intervals The 'test frequency for pumps included in the Program will be as set forth in the OM Code, paragraph ISTB-3400, and related relief requests. An allowable extension, not to exceed +25 percent of the surveillance interval may be applied to a test schedule as allowed by the Calvert Cliffs Nuclear Power Plant Technical Specifications to provide for operational flexibility.

The frequencies used for scheduling pump tests are defined as:

Quarterly - 92 days Refueling - 730 days Cold Shutdown - Per the applicable Relief Request consistent with the cold shutdown testing requirements for valves in the OM Code. When all cold shutdown testing will not be completed, priorities for testing will be established per approved CCNPP procedures.

4.4 Pump Program Tables list those pumps included in the IST Program with references to parameters to be measured and applicable requests for relief.

4.5 Relief Requests for Pump Testing Relief requests are/were submitted per 10CFR50.55a where appropriate and are included in Attachment 1.

4.6 Instrument Accuracy Instruments will meet the requirements specified in the OM Code, paragraph ISTB-3500, and amplified in NUREG 1482, Revision 1, Section 5, except where specific relief is granted.

4.7 Vertical Line Shaft Pumps Paragraph ISTB-2000 of the OM Code defines a Vertical Line Shaft pump as "a vertically suspended pump where the pump driver and the pump element are connected by a line shaft within an enclosed column." In a vertical line shaft pump configuration, the pump bearings would be submerged in the pumped fluid and inaccessible. The Salt Water pump configuration does not meet the OM Code paragraph ISTB-2000, vertical line shaft pump definition.

7 OF 14

ConstellationEnergy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 These pumps are not "vertically suspended." They are mounted in a dry pit located at the intake structure with pump orientation such that they take suction through the intake structure floor. The drive motor is mounted on an elevated platform above the pump and connected to the pump via an exposed shaft. This design allows pump operation in the event of flooding. However, the salt water pump bearings are accessible and the shaft is not "within an enclosed column." CCNPP considers these pumps to be horizontal centrifugal pumps.

4.8 Pump Design Flow Comprehensive pump testing is required to be performed with the pump operating within 20% of design flow. The OM Code does not; however, define the term "design" flow. The industry has considered 4 different definitions: 1) the pump manufacturer's design flow for the pump, 2) the pump's best efficiency point (BEP), 3) the system design flow, and 4) the maximum required accident flow rate. The NRC has stated their position as this "design" flow rate must be at least the maximum credited accident flow rate. CCNPP has determined that for the comprehensive pump testing the selected reference flow rate will be at least the maximum credited accident flow rate as stipulated by the NRC.

ConstellationEnergy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev O00 Valve Information 5.0 INSERVICE TESTING PROGRAM FOR VALVES 5.1 Code Compliance This IST Program for valves meets the requirements of Subsections ISTA and ISTC of the OM Code and any applicable interpretations or clarifications of existing requirements provided by NUREG 1482, Revision 1.

Paragraph and table references in this section refer to specific paragraphs and tables in the OM Code. Where these requirements have been determined to be impractical, an alternative test provides an acceptable level of quality and safety, or conformance would cause unreasonable hardship without any compensating increase in safety, relief from Code requirements is/was requested pursuant to the requirements of 10CFR 50.55a(f)(5)(iii),

10CFR50.55a(a)3(i) or 10CFR50.55a(a)3(ii).

5.1.1 Code Case OMN-1 ASME OM Code Case OMN-1, "Alternative Rules for Preservice and Inservice Testing of Certain Motor-Operated Valve Assemblies in Light-Water Reactor Power Plants," allows the use of MOV diagnostic testing as an alternative to stroke time testing and position indication verification for certain motor operated valves. Use of this Code Case is authorized by Regulatory Guide 1.192, "Operation and Maintenance Code Case Acceptability, ASME OM Code." This Regulatory Guide lists ASME OM Code Cases determined acceptable for use in IST Programs by the NRC. The Regulatory Guide is incorporated by reference in the Code of Federal Regulations 10CFR50.55a(b). The Code Case is listed in Table 2 of this Regulatory Guide as a conditionally approved Code Case. A conditionally approved Code Case may be used without request to the NRC provided it is used with any identified limitations or modifications. The stipulations listed in Table 2 include the following:

(1) The adequacy of the diagnostic test interval for each motor-operated valve (MOV) must be evaluated and adjusted as necessary but not later than 5 years or three refueling outages (which ever is longer) from initial implementation of OMN-1.

(2) When extending exercise test intervals for high risk MOVs beyond a quarterly frequency, ensure that the potential increase of Core Damage Frequency (CDF) and risk associated with the extension is small and consistent with the intent of the Commissions Safety Goal Policy Statement.

(3) When applying risk insights, MOVs must be categorized according to their safety significance using the methodology described in Code Case OMN-3 or use other MOV risk ranking methodologies accepted by the NRC on a plant specific or industry-wide basis.

This Code Case will be used, (upon approval of Relief Request GV-RR-02), with the associated stipulations, as an alternative to the motor-operated valve testing required by the OM Code in Subsection ISTC. The valve tables will be annotated with "OMNI" in the "Frequency" column as appropriate.

5.1.2 Code Case OMN-8 ASME OM Code Case OMN-8, "Alternative Rules for Preservice and Inservice Testing of Power-Operated Valves That Are Used for System Control and Have a Safety Function per OM-10," provides an alternative to stroke time testing of system control valves whose only safety function is to "fail-safe" to either the open or close position.

This Code Case will be used, (upon approval of Relief Request GV-RR-03) for certain control valves. Use of the Code Case will be annotated in the Program tables "Remarks" column as appropriate.

5.2 Stroke Time Acceptance Criteria When required, the acceptance criteria for the stroke times of power-operated valves will be as set forth in the OM Code, Subsection ISTC.

5.3 Check Valve Testing 9 OF 14

Constellation Energy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 5.3.1 Test Methods Check valves are full-stroke exercised in the open direction using the following methods:

Using system flow equal to, or greater than, the required accident flow rate (plus allowance for analytical and instrument uncertainties).

. Non-intrusive monitoring, or other positive means, that verifies the valve disk reaches the fully-open position (recording flow rate is not necessary).

Mechanical exercising.

Other methods that satisfy the requirements of GL 89-04, Position 1 or as specified in an approved relief request.

Check valves are full-stroke exercised in the closed direction using the following methods:

- Verifying system flow equal to, or greater than, the required accident flow rate (plus allowance for analytical and instrument uncertainties) is achievable in a parallel flow path when the check valve being tested forms a boundary for that flow path.

- Measuring check valve gross leakage or performing a gross pressure drop test to verify the valve disk is in the closed position.

' Non-intrusive monitoring, or other positive means, that verifies the valve disk opens and then returns to the fully-closed position (recording leakage is not necessary unless required for Category Avalves).

Mechanical exercising.

Other methods that satisfy the requirements of GL 89-04, Position 1 or as specified in an approved relief request.

5.3.2 Non-Intrusive Check Valve Testing As discussed in NUREG-1482, Revision 1, Section 4.1.2, the NRC determined that the use of non-intrusive techniques is acceptable to verify the full stroke of a check valve. The licensee may use non-intrusive techniques to verify the capability to open, close, and fully stroke in accord with quality assurance program requirements.

These techniques are considered "other positive means" in accordance with paragraph ISTC-5221 (a), and relief is not required except as would be necessary for the testing frequency ifthe test interval extends beyond each refueling outage as allowed by the OM Code.

During the initial test of each valve, non-intrusive techniques will be used to verify that the system pressures and flow conditions specified in the test procedures cause the valves to fully stroke. Initial testing of check valves using non-intrusive techniques shall only be performed when the valve is known to be operating acceptably.

During subsequent testing, ifthe system conditions are repeatable, each valve would typically be stroked and monitored using non-intrusive techniques.

Another alternative that may be employed is radiography. The position of the disk and the general condition of the internals may be determined using the radiographic method. This methodology is normally used for verification of valve closure only.

5.3.3 Check Valves Verified Closed by Leak Testing The OM Code requires that check valves performing a safety function in the closed position be exercised to that position. Certain of these valves cannot be verified in the closed position quarterly because they do not have remote position indication and are generally located inside reactor containment or at other inaccessible locations.

These valves may lack design provisions for system testing to verify closure capability at any plant condition. The only practical means of verifying valve closure may be by performing a seat leakage test. Many of these valves are Category AC valves that are Type C leak-rate tested during each refueling outage as specified in Appendix J to 10 CFR Part 50.

If no other practical means is available, it is acceptable to verify that check valves are capable of closing by performing leak-rate testing, such as local leak rate testing in accordance with Appendix J to 10 CFR Part 50, at each reactor refueling outage. Recognizing that the setup and performance limitations may render leak testing 10 OF 14

Constellation Energy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 impractical during power operation and cold shutdown outages, the NRC has determined that implementation of an extension of the test frequency for such valves is acceptable in accordance with 10 CFR 50.55a(f).

In accordance with paragraph ISTC-5222, and as discussed in NUREG-1482, Revision 1, Section 4.4.7, as an alternative to check valve closure verification by Type C seat leakage testing at refueling, the Appendix II Check Valve Condition Monitoring Program could justify extending the exercise test interval to the leak test frequencies specified in Option B of Appendix J based on the valve's performance and operating condition.

5.3.4 Check Valve Disassembly and Inspection When using check valve disassembly in a sampling plan, the IST Program may implement testing such that similar valves in the same service are grouped for testing purposes, not to exceed four valves in a single group (for valve groups of greater than four, the grouping and test schedule must be justified in the description of the testing plan). The sample examination program shall group check valves of similar design, application, and service condition and require a periodic examination of one valve from each group. Grouping of check valves shall be technically justified and shall consider, as a minimum, valve manufacturer, design, service, size, materials of construction, and orientation. Maintenance and modification history should be considered in the grouping process. The details and bases of the sampling program shall be documented and recorded. (paragraph ISTC-5221 (c))

During the disassembly process, the full-stroke motion of the obturator shall be verified. Full-motion of the obturator shall be re-verified immediately prior to completing reassembly. Check valves that have their obturator disturbed before full-stroke motion is verified shall be examined to determine if a condition exists that could prevent full opening or closure of the obturator.

At least one valve from each group shall be disassembled and examined at each refueling outage; all valves in each group shall be disassembled and examined at least once every 6 years (8 years if on a 24 month fuel cycle).

If problems are found with the sample valve, that are determined to affect the operational readiness of the valve, all valves in the group must be tested during the same outage.

Before return to service, valves that were disassembled for examination or.that received maintenance that could affect their performance; shall be exercised, full or part stroke if practicable, with flow in accordance with paragraph ISTC-3520. Those valves shall also be tested for other applicable requirements (e.g., closure verification or leak rate testing) before returning them to service.

As an alternative to the aforementioned disassembly and inspection frequency, the Appendix II Check Valve Condition Monitoring Program could justify extending the disassembly and inspection !nterval to reduce the burden of unnecessary IST based on previous disassembly and inspection results.

5.3.5 Check Valve Condition Monitoring As an alternative to the testing or examination requirements of paragraphs ISTC-351 0, ISTC-3520, ISTC-3530, ISTC-3550, and ISTC-5221, CCNPP will establish a check valve condition monitoring program per paragraph ISTC-5222 and implement the program in accordance with Appendix II "Check Valve Condition Monitoring Program."

The purpose of this program is to both (a) improve check valve performance and to (b) optimize testing, examination, and preventive maintenance activities in order to maintain the continued acceptable performance of a select group of check valves.

Examples of candidates for (a) improved valve performance are check valves that: (1) have an unusually high failure rate during inservice testing or operations; (2) cannot be exercised under normal operating conditions or during shutdown; (3) exhibit unusual, abnormal, or unexpected behavior during exercising or operation, or (4) 11 OF 14

ConstellationEnergy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 CCNPP elects to monitor for improved valve performance.

Examples of candidates for (b) optimization of testing, examination, and preventive maintenance activities are check valves with documented acceptable performance that: (1) have had their performance improved under the Condition Monitoring Program; (2)cannot be exercised or are not readily exercised during normal operating conditions or during shutdowns; (3) can only be disassembled and examined, or (4) CCNPP elects to optimize all the associated activities of the valve or valve group in a consolidated program.

Ifthe Appendix II Condition Monitoring Program for a valve or valve group is discontinued then the requirements of paragraphs ISTC-3510, ISTC-3520, ISTC-3530, ISTC-3550, and ISTC-5221 must be implemented.

Valves included in the Check Valve Condition Monitoring Program (CVCMP) will be annotated with "CMP" in the "Frequency" column of the Valve Tables. The Code testing specified in the Tables is replaced by the activities/tests identified in the specific CMP Plan.

5.4 Manual Valves Manual valves within the scope of IST that perform an active safety function shall be exercised at least once every 2 years as required by 10 CFR 50.55a(b)(3)(vi).

5.5 Testing Intervals The test frequency for valves included in the Program will be as set forth in the OM Code, paragraph ISTC-3510 and related relief requests. An allowable extension, not to exceed +25 percent of the surveillance interval, may be applied to the test schedule as allowed by the CCNPP Technical Specifications to provide for operational flexibility.

The frequencies used for scheduling valve tests are defined as:

Quarterly - 92 days Refueling - 730 days 2 Year - 730 days Per App. J - Leak Rate Testing frequency determined by Appendix J requirements.

Sampling - For safety/relief valves, set-point testing per the applicable population sampling requirements specified in OM Code, Appendix I.

Sampling - For check valves, disassembly and inspection per the applicable population sampling requirements specified in Subsection ISTC-5221(c).

Cold Shutdown - Consistent with the cold shutdown testing requirements for valves of the OM Code, paragraphs ISTC-3521(f), (g), & (h) and ISTC-3522(d), (e), & (f), and NUREG 1482, Revision 1, Sections 3.1.1, 3.1.1.1 and 3.1.1.2. When all cold shutdown testing will not be completed, priorities for testing will be established per approved CCNPP procedures.

Per the OM Code, paragraphs ISTC-3550 and ISTC-3610, valves in regular use and valves which demonstrate functionally adequate seat tightness during normal operation are not required to be additionally tested as long as the required observations and analyses are performed and documented at the otherwise required test frequency.

The frequency indicated in the valve table for such valves is the applicable required test frequency.

5.6 Valve Program Tables Specific tables list those valves included in the IST Program with references to required testing, respective test intervals, and applicable requests for relief. The following notations are used in the valve tables to identify required testing.

The valve program tables identify those valves to which deferred testing applies and the respective technical justification for each is provided in an associated cold shutdown or refueling outage justification. The criteria for determining appropriate justification is based on NUREG 1482, Revision 1, Paragraphs 2.4.5, 3.1.1, and 4.1.6 as well as OM Code, paragraphs ISTC-3521 (b), (c), (d) & (e) and ISTC-3522(b), & (c). The schedule and extent of testing valves during cold shutdown periods will be based on the requirements of OM Code, paragraphs ISTC-3521 (f), (g), & (h) and ISTC-3522(d), (e), & (f), and NUREG 1482, Revision 1, Sections 3.1.1.1 & 3.1.1.2. When all cold shutdown testing will not be completed, priorities for testing will be established per approved CCNPP procedures.

OM Code, paragraphs ISTC-3521 (h) and ISTC-3522(f) require that for valves tested during refueling outages, all testing must be completed prior to returning the plant to operation. For those cases where valves can be tested during power ascension and where the Technical Specification requirements for the valves or system determine when the valves are required to be operable, tests may be performed during power ascension. This position conforms to that stated in NUREG 1482, Revision 1, Section 3.1.1.2.

The majority of Calvert Cliffs' Test Deferral Justifications have been written for cold shutdown periods, vice only refueling outages. Many of these cold shutdown tests require very specific and unique plant conditions that may not be common during an "average" cold shutdown period. This limits Calvert Cliffs' ability to perform these tests.

However, they are classified as cold shutdown tests, vice refueling tests, because ifthe appropriate plant conditions exist during a cold shutdown period and the opportunity presents itself, the appropriate tests can be performed.

5.8 Relief Requests for Valve Testing Relief requests associated with valve testing are/were submitted and are provided in Attachment 1.

5.9 Active and Passive Valves 5.9.1 Active Valves Valves and pressure relief devices that perform a mechanical motion during the course of accomplishing a safety function are active components. Ifa valve is capable of being moved out of its safety position during either normal operation, and/or accident response and it must be capable of returning to that safety position, then the valve is considered to be active for that safety function.

13 OF 14

ConstellationEnergy (CCNPP Unit 1) IST Program PUMP AND VALVE INSERVICE TESTING PROGRAM FOURTH TEN-YEAR INTERVAL Revision Rev 00 NUREG 1482, Revision 1, Section 2.4.2, states that valves need not be considered active ifthey are only temporarily removed from their safety position for a short period of time and would be considered active only ifthe valve is routinely repositioned during power operation.

5.9.2 Passive Valves A valve is considered passive for a given safety function if, to perform that safety function, it is not required to move or be capable of moving (i.e. not even part-stroke or fail-safe) at any time. This means the valve must remain in that position any time the safety function might be required. This includes normal operation, as well as post-accident response until the safety function would no longer be required. Ifa valve does not meet this general criterion, then it should be considered to be active for that safety function. Passive valves include those valves required to perform a nuclear safety function by maintaining their position.

5.9.3 Normal Position Some valves may be moved to an alternate position during plant operations that is different from their normal position, such as to support surveillance testing. Ifthe valve is still relied on while in its alternate position to accomplish its safety function in its normal position, then the ability to return to its normal position from its alternate position must be considered to be an active valve function that is subject to IST requirements, even ifthe valve is only in the alternate position for a short period of time. Inthis case, the alternate position is also listed in the "Normal Position" column in the Valve Tables to ensure this test requirement is captured. (The only other alternative is to consider the valve inoperable while it is out of its normal position.)

5.10 Valve Category 5.10.1 Category A Per the OM Code, these are valves for which seat leakage is limited to a specific maximum amount in the closed position for fulfillment of their required function(s). Category A applies to valves for which a specific maximum valve leakage limit exists.

5.10.2 Category B Per the OM Code, these are valves for which seat leakage in the closed position is inconsequential for fulfillment of the required function(s). Inconsequential implies a leakage limit does not exist relative to the valve's ability to perform its safety function. However, leakage past a closed valve above some level indicates the valve may be degrading and its ability to close at all (e.g., "gross" closure capability) may become threatened at some point.

5.10.3 Category C Per the OM Code, these are valves which are self-actuated in response to some system characteristic, such as pressure (relief valves) or flow direction (check valves) for fulfillment of the required function(s). Ifseat leakage in the closed position is consequential for a Category C valve, then it is categorized as "AC". Ifseat leakage in the closed position is not consequential for a Category C valve, then it may be categorized "BC". However, such valves are merely categorized as "C"and the "B"is considered to be implied. "Gross" leakage past a closed category C valve may still be used as the desired test parameter to detect when the valve may be degrading and its ability to close at all (e.g., "gross" closure capability) may become threatened, without implying the valve should be categorized AC.

Constellation Energy (CCNPP Unit 1) IST Program AFW-CSJ-01 These are simple check valves with no external means of exercising. The only way to stroke these check valves fully open is to operate each AFW pump at the full accident flow rate while discharging to the steam generators.

Previously, the primary basis for not performing full flow testing during plant operation at power was due to the potential for thermal shock/fatigue of the steam generator nozzles or internals. Recent studies using more sophisticated analytical tools/methods indicate that the magnitude of the thermal shock and the thermal transients on the fatigue life of steam generator components would not be as significant as previously thought. However, such testing every quarter would still use up a significant portion of the allowable thermal cycles for these components.

Additionally, such testing every quarter also presents several other challenges/drawbacks:

Reducing reactor power prior to, and during, each test would be required in order to account for the positive reactivity (since the moderator temperature coefficient is negative throughout most of each operating cycle) caused by adding significant amounts of colder auxiliary feedwater into the steam generators (compared to main feedwater). The combination of the required reactor down-power and addition of positive reactivity due to the colder auxiliary feedwater, especially on such.a frequent basis, is viewed as creating an increased risk of a plant trip and a reactivity management concern. Furthermore, coordinating a power reduction for AFW testing with other evolutions requiring a reduced power would complicate all these trip-risk evolutions and/or extend the period of reduced power.

Sending flow into the steam generators opens check valves 1/2-AFW-129 and 1/2-AFW-130. The primary purpose of these check valves is to isolate the AFW system piping from the steam generators so that the AFW piping may be considered to be medium-energy, vice high energy, lines during plant operation. By opening these check valves, it is possible that they may not close or seat properly. As a result, a portion of the upstream AFW piping outside containment would become high-energy lines. (This is not considered to be an issue post-accident because once AFW is initiated, these lines become pressurized anyway.) There not many ways.to positively verify valve closure and non-intrusive monitoring is the only way to rapidly verify valve closure because monitoring upstream piping temperature requires a longer time. Additionally, steam binding of a turbine-driven AFW pump could also occur if the check valves in a given AFW flow leg fail to seat tightly.

The introduction of AFW flow into the steam generators will require a commensurate adjustment by the feedwater control system to maintain the desired steam generator level. These perturbations could potentially affect the stability of the feedwater control system operation.

Full-stroke exercising the check valves requires feeding the steam generators. The test currently performed during cold shutdown periods and/or refueling outages that accomplishes this adds approximately 6300 gallons into each steam generator. The supply for both the Unit 1 and Unit 2 AFW pumps is the safety-related 12 Condensate Storage Tank (12 CST). Quarterly testing would remove approximately 12,600 gallons per Unit from 12 CST each quarter and over 100,000 gallons total each year. This water cannot directly be returned to 12 CST.

This would greatly complicate the management of the safety-related water inventory in 12 CST to ensure continuous compliance with the minimum 12 CST inventory requirements specified by the Technical Specifications.

During quarterly testing of the AFW pumps, flow is routed through a minimum flow recirculation line branching off upstream of these check valves that returns condensate to the condensate storage tank and the respective pump's suction line. The manual discharge valve associated with the running pump must be shut in order to prevent injecting flow into the steam generators while still maintaining the ability to supply the.steam generators from the non-running AFW pump in the event of an emergency. Therefore, no flow passes through the discharge check valve and a part-stroke exercise is not possible. Since there is no flow into the common AFW discharge header, the header remains depressurized and it is not possible to statically verify the discharge check valve of the non-running AFW pump is closed.

This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

In addition, they are internally ported to pass 140 gpm to the recirculation header for minimum pump flow regardless of the valves' position.

The motor-driven AFW pump for each Unit does not share the common discharge header that the turbine-driven pumps share. Therefore, there is no practical way to pressurize this header for a static closure test using the turbine-driven AFW pumps.

2 OF 3

Constellation Energy (CCNPP Unit 1) IST Program AFW-CSJ-02 This check valve can be reverse-flow tested using the motor-driven AFW pump from the other Unit. However, opening the cross-connect valve impacts the AFW systems for both Units. For example, it requires the motor-driven train flow paths to the steam generators of both Units to be isolated in order to prevent injecting AFW flow into the steam generators. This becomes a complicated evolution that increases the risk to both Units and simultaneously places the AFW motor-driven trains out of service for both Units. (Without first exercising the check valve open, such a test would only be a static closure verification.) Therefore, performing such a test every quarter is not considered prudent. During cold shutdown periods (depending on plant conditions), as well as during refueling outages, the risk involved in performing this test is reduced by the fact that one Unit is already shut down.

This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

These valves will be full stroke exercised open and closed during cold shutdowns.

Containment isolation valves, close on a CIS. On a rupture of the non-classed piping inside containment these valves are closed to provide Code Class boundary isolation.

TEST REQUIREMENT:

OM Code paragraph ISTC-351 0 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

These normally-open valves provide flow paths for cooling water (normal cooling) to and from the control rod drive mechanisms, reactor coolant pumps, and the reactor and steam generator supports. Closing any of these valves during plant operation at power will interrupt cooling flow and cause overheating and damage to the associated components. Should any one of these valves fail to re-open after closure, an immediate plant shutdown or trip and cooldown would follow. Partial closure of these valves presents the same risk as full closure; thus it is also not feasible during operation. This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

Additionally, it is consistent with NUREG-1482, Rev. 1, Paragraph 3.1.1.4, component cooling containment heat loads (such as the RCPs) will not necessarily be secured solely to test these valves.

ALTERNATE TESTING:

These valves will be exercised and stroke timed during each reactor refueling outage and during cold shutdowns of sufficient duration when the RCPs are secured.

OM Code paragraph ISTC-3510 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

These valves are normally locked shut with power removed in Modes 1-4 per Technical Specification 3.6.1.7.

They are only required to stroke in Modes 5 and 6 in the event of a refueling accident. During all other modes of operation, they remain closed and are essentially passive. If containment purge is established during a cold shutdown period, then these valves will be stroke tested; however, they are not necessarily opened during each cold shutdown period. Note that, if they are not opened they remain in their safety position and are not required to be operable with respect to their automatic closure capability. It is undesirable to stroke these valves during each cold shutdown since excessive operation can damage the sealing surfaces of these valves and cause degradation of the valve's leak-tight capability which would result in additional testing, maintenance, and potential cold shutdown extension. Partial closure of these valves presents the same risks and problems that are associated with full closure; thus it is also not feasible during operation. This is consistent with the position stated in NUREG-1482 Rev. 1, Paragraph.2.4.5. Note that these valves are not within the ASME/ISI class boundaries.

These valves will be stroke tested during each refueling outage and during cold shutdown periods whenever containment purge is established.

During emergency boration operations these valves open to provide flow paths from the boric acid storage tanks to the charging pump suction header. They close to prevent recirculation from the emergency boration line when the boric acid pumps are operating.

TEST REQUIREMENT:

OM Code paragraph ISTC-351 0 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

These are simple check valves with no means of noting obturator position nor for manual exercising. Exercising these valves in the open direction requires realignment of the CVCS system and injection of concentrated boric acid into the reactor coolant system via the charging pumps. During plant operation this could disrupt the CVCS system balance with the potential for causing severe pressurizer level transients or reactor coolant make-up boron concentration variations. Partial-stroke exercising of these valves in the open direction presents the same risks and problems that are associated with full-stroke exercising, thus it is also not feasible during operation. These valves can be confirmed closed (statically tested) quarterly. This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

During emergency boration operations these valves open to provide flow paths from the discharge of the boric acid pumps to the charging pump suction headers.

TEST REQUIREMENT:

OM Code paragraph ISTC-351 0 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

These are simple check valves with no means of noting obturator position nor for manual exercising. Exercising these valves in the open direction requires injection of concentrated boric acid into the reactor coolant system via the charging pumps. During plant operation this could disrupt the CVCS system balance with the potential for causing severe pressurizer level transients or reactor coolant make-up boron concentration variations.

Partial-stroke exercising of these valves presents the same risks and problems that are associated with full-stroke exercising, thus it is also not feasible during operation. This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

If emergency boration is initiated while concentrated boric acid is being added to the VCT, this check valve must close to prevent diversion of boric acid into the demineralized water system and ensure sufficient boric acid is delivered to the suction of the charging pumps.

ConstellationEnergy (CCNPP Unit 1) IST Program CVC-CSJ-03 Verifying the ability of this check valve to close requires applying a back-pressure. The only source of a back-pressure during normal operation is a boric acid pump (temporarily installing a test pump each quarter is not considered practical).

However, the boric acid pump discharge pressure is high enough to create a concern regarding possible introduction of concentrated boric acid into the VCT. This could occur due to leakage past 1/2-CVC-512-CV into the VCT (since there are no isolation valves between 1/2-CVC-512-CV and the VCT) or by lifting 1/2-CVC-194-RV.

Relief valve 1/2-CVC-194-RV is configured to relieve around 1/2-CVC-512-CV into the VCT. Its set point is 123

+0/-2 psig. The only way to apply a test pressure against 1/2-CVC-251 is to run a Boric Acid pump using a modified minimum recirculation flow path. This also places.the same pressure against 1/2-CVC-512-CV and 1/2-CVC-194-RV. Historical pump test results show the discharge pressure of the Boric Acid pumps under low flow conditions typically falls in the range of 117 psig to 127 psig. This will clearly challenge 1/2-CVC-1 94-RV.

Regardless of the source (i.e. leakage past 1/2-CVC-512-CV or lifting of 1/2-CVC-194-RV) inadvertent addition of concentrated boric acid into the VCT can have an effect on reactivity control. (Under accident conditions with CV21OY open, such in-leakage into the VCT does not present a concern because enough boric acid will still reach the charging pump suction.) However, during power operation, any leakage of concentrated boric acid into the VCT will affect reactivity and possibly cause a reactor power transient. Furthermore, as the fuel cycle progresses and less boric acid is required in the RCS, the impact of such a reactivity change will become more pronounced.

Late in the fuel cycle, reactor power becomes still more sensitive to even small changes in reactivity.

The significance of such an inadvertent addition of concentrated boric acid into the VCT increases during the fuel cycle as the VCT boron concentration is reduced and batch adds of concentrated boric acid become less frequent.

It may be physically possible to attempt to mitigate this addition of concentrated boric acid into the VCT by injecting reactor make-up water directly into the charging pump suction or into the VCT. However, it would be impossible to know exactly how much concentrated boric acid was added to the VCT until after it occurred. As a result, the Operators would be put in a position of reacting to a change in reactivity rather than controlling a change in reactivity. This is not considered to be prudent.

When concentrated boric acid is batch added to the VCT during power operation, the operators are required to verify the plant response by checking the appropriate parameters, including VCT level, VCT pressure, and boric acid flow rate. The piping upstream of 1/2-CVC-251 includes the normally shut control valve 1/2-CVC-210X-CV and check valves 1/2-CVC-244 and 1/2-CVC-247. However, relief valve 1/2-CVC-376-RV is located between 1/2-CVC-251 and 1/2-CVC-210X-CV. Its setpoint is 72 +0/-2 psig. Even at their maximum flow rate, the discharge pressure of the Boric Acid pumps is greater than 100 psig. Therefore, if 1/2-CVC-251 is leaking but the upstream valves are leak-tight, it is likely that 1/2-CVC-376-RV will lift. If the valves upstream of 1/2-CVC-251 are also leaking, than there will be a discrepancy between the level increase noted in the VCT and the total flow indicated by the 1/2-FIC-210Y Boric Acid Integrator Reading.

This effectively verifies 1/2-CVC-251 is adequately closed. After each addition of concentrated boric acid to the VCT, demineralized water is used to flush the piping. This also strokes 1/2-CVC-251 open. Therefore, over time, this check valve is at least part-stroked open and closed several times. However, since the degree of RCS boration declines as the fuel cycle progresses, the frequency of adding concentrated boric acid to the VCT also decreases. (t is not practical to add concentrated boric acid to the VCT solely for the purpose of part-stroking 1/2-CVC-251.) Additionally, during power operation, changes to the VCT boric acid concentration are made by simultaneously adding demineralized water and concentrated boric acid to achieve the desired blended mixture.

Batch adds of boric acid are very rare and short-lived in duration, such as, to perform a small downpower for turbine valve testing or waterbox cleaning.

Since this evolution is not performed on a consistent basis, these check valves are not typically operated in the manner described on a reliable schedule. Therefore, this is not considered to be a true a periodic closure verification of these check valves.

This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

These normally-open valves close following a containment isolation signal when downstream line pressure drops to 75 psig. to extend the air supply to the containment air inlet valves and other critical containment air loads for as long as possible. This also ensures that it is safe to re-open 1/2-2080-MOV later in an accident scenario to allow operation of CVCS valves 1/2-CVC-517-CV, 1/2-CVC-518-CV, and 1/2-CVC-519-CV and the PASS isolation valves.

TEST REQUIREMENT:

OM Code paragraph ISTC-3510 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

Closing these valves will isolate instrument air to the containment and secure operating air to several components critical for plant operation including the pressurizer spray control valves. If the valve were to fail in the closed position, a plant shutdown would be required. Partial closure of these valves presents the same risk as full closure; thus, it is also not feasible during operation.

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

This valve is a small spring-loaded piston-type check valve with no external position indication or other means of easily verifying its position.

Operation of numerous air-operated control valves in containment during normal operation, including quarterly surveillance testing of selected air-operated control valves in containment, verifies the ability of the check valve to open on an ongoing basis.

There is no means of verifying its ability to full-stroke closed other than by performing a back seat leakage test. In order to do this, the upstream side of the check valve must be isolated and a test connection removed through which air flow can be verified after passing back through the check valve. However, this secures at least one, and sometimes the only, flowpath for safety-related air to the downstream air loads. Verifying closure of this valve requires containment access and a back-leakage test. Such access is not practical on a routine basis during plant operation at power. The coordination and resources needed to secure instrument air to the containment to permit testing during cold shutdown periods would be an unreasonable burden with no appreciable gain in plant safety.

Performing this test requires extensive system realignments which (1) effect operation of the AFW valves supplied by this portion of the IA system, (2) includes opening numerous capped test connections and (3) has the potential to effect operation of air operated valves in other systems. The number of instrument air valves, the complex system re-alignments, and the necessity of removing and replacing numerous test connection caps is considered impractical to perform during normal operation or during cold shutdown periods. This is consistent with NUREG-1482, Rev. 1, Sections 3.1.1 and 4.1.6. Note that this check valve is an augmented component and is not within the ASME/ISI class boundaries.

Verifying closure of these valves requires isolation of the normal air supply to critical system components inside containment. Although there is a backup supply of air stored in the associated containment air receiver, failure to return the normal supply to service in a timely manner could result in equipment failure and plant shutdown. Also, the backup air supply is capable of providing air to only a limited number of critical loads.

Performing these tests requires extensive system realignments which (1) effect operation of the AFW valves supplied by this portion of the IA system, (2) include opening numerous capped test connections, (3) include installing and removing flow rate instrumentation and leak rate instrumentation at numerous locations, and (4) has the potential to effect operation of air operated valves in other systems.

Testing these valves requires significant re-alignment of the air supplies to the AFW flow control valves, including securing the safety-related air supply to each set of AFW Blocking valves and Flow Control valves (one set at a time). The air headers/safety-related accumulators are configured such that one of the two AFW Blocking valves in each AFW Flow Leg is supplied by independent air headers/accumulators. As a result, isolating one safety-related air accumulator isolates air to one AFW Blocking valve in each AFW Flow Leg. Since the AFW Blocking valves fail open, this would result in limited capacity of the AFW supply system to respond to an ASFAS in the event steam generator isolation should be required. Therefore, all AFW Flow Legs would be rendered inoperable.

These check valves close to isolate the normal (NSR) instrument air header from the safety-related air header to maintain supply train isolation and preclude blowdown of the associated AFW air accumulator. They also open in the event SWAC air is aligned to the AFW portion of the IA System.

TEST REQUIREMENT:

OM Code paragraph ISTC-3510 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

These are small spring-loaded piston-type check valves with no external position indication or other means of easily verifying their position. Due to their size, design, and system configuration, they cannot be non-intrusively monitored.

There are no means of verifying their ability to full-stroke open other than passing the required air flow in the forward direction. This can only be achieved by either isolating the normal non-safety-related sources of air and operating the downstream air loads simultaneously. However, operating all the downstream air loads simultaneously is not typically practical. Alternatively, the forward flowrate through each check valve may individually measured. In order to do this, the downstream side of each check valve must be isolated and a test connection removed through which air flow can be measured using a flow instrument after passing through the check valve.

There are no means of verifying their ability to full-stroke closed other than by performing a back seat leakage test.

In order to do this, the upstream side of each check valve must be isolated and a test connection removed through which air flow can be measured using a leak rate monitor after passing back through the check valve.

Performing these tests requires extensive system realignments which (1) effect operation of the AFW valves supplied by this portion of the IA system, (2) include opening numerous capped test connections, (3) include installing and removing flow rate instrumentation and leak rate instrumentation at numerous locations, and (4) has the potential to effect operation of air operated valves in other systems. The number of instrument air valves, the complex system re-alignments, the necessity of removing and replacing numerous test connection caps, and the difficulty of installing, removing, and relocating a flow instrument and leak rate monitor to test each check valve is considered impractical to perform during normal operation or during cold shutdown periods. This is consistent with NUREG-1482, Rev. 1, Sections 3.1.1 and 4.1.6. Note that these check valves are augmented components and are not within the ASME/ISI class boundaries.

ALTERNATE TESTING:

These valves will be full-stroke exercised in the open and closed directions during refueling outages in accordance with OM Code paragraph ISTC-3522.

FUNCTION:

These valves close on CSAS and SGIS to prevent the unrestricted release of steam from multiple steam generators in the event of an upstream steamline rupture and to isolate the steam generators in the event of a LOCA, steam generator tube rupture, or downstream steamline rupture. When closed, they provide isolation of the unaffected steam generator thus ensuring an adequate supply of steam for AFWpump turbine operation.

These valves are also required to be tested per Technical Specifications SR 3.7.2.1.

TEST REQUIREMENT:

OM Code paragraph ISTC-351 0 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

During plant operation at power, full closure of any of these valves would result in a major plant transient and a turbine and reactor plant trip.

These valves are provided with the capability of partial stroke (closure) exercising; however, the valves will not be part stroke exercised quarterly based on the guidance from NUREG-1482, Revision 1, Section 4.2.6, Note:

Related to MSIVs, a number of plants perform a partial-stroke exercise quarterly during power operations. The revised standard techncial specifications bases for MSIV surveillance requirements states that "MSIVs should not be tested at power, since even a part-stroke exercise increases the risk of a valve closure when the unit is generating power."

ALTERNATE TESTING:

These valves will be full-stroke exercised, verifying stroke time in the closed direction following a cold shutdown period in accordance with OM Code paragraph ISTC-3521.

The Atmospheric Dump Valves automatically open in response to system transients and also function (open and close) as control valves. The valves are designated closed-piping system containment isolation valves per UFSAR Figure 5-10 that are exempted from App. J LLRT.

TEST REQUIREMENT:

OM Code paragraph ISTC-351 0 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

The atmospheric dump valves are positioned by the reactor coolant average temperature error signal when the turbine is tripped. In the event of a turbine trip above a preset power level, a quick-opening signal is provided to fully open the atmospheric dump valves. When Tavg is reduced to less than T?, the steam dump valves are modulated as a function of Tavg. The total capacity of the atmospheric steam dump valves are 5% of steam flow with the reactor at full power. This flow is sufficient to control the secondary steam pressure on a turbine trip at full power without necessitating operation of the spring-loaded safety valves.

Full/part-stroking these valves during power operation would release main steam to the atmosphere and could cause significant and unacceptable secondary steam pressure transients. Additionally, such stroking could also result in the failure of one of these valves to reseat properly which would lead to system/equipment damage, reduced plant reliability, and a possible plant shutdown. This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

ALTERNATE TESTING:

These valves will be full-stroke exercised in the closed direction during cold shutdowns in accordance with OM Code paragraph ISTC-3521.

These valves provide flow paths for borated water from the HPSI and LPSI pumps to each of the RCS cold legs.

They close to isolate the safety injection system from the reactor coolant system. They also serve as pressure isolation valves (PIVs) during normal operation.

TEST REQUIREMENT:

OM Code paragraph ISTC-3510 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

These are simple check valves with no external means of exercising, thus exercising (open) requires operating a LPSI pump at full flow and injecting into the reactor coolant system. At power operation, this is not possible because the LPSI pumps cannot develop sufficient discharge pressure to overcome reactor coolant system pressure. These valves are part-stroked exercised open quarterly and whenever the associated HPSI pump is run to fill a safety injection tank and verified closed quarterly. The full-stroke exercise open and closed is accomplished during cold shutdown periods (depending on plant conditions) and every refueling outage. This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

ALTERNATE TESTING:

These valves will be full-stroke exercised, in the open and closed directions during cold shutdowns in accordance with OM Code paragraph ISTC-3522.

These check valve form the safety-related to non-safety boundary of the nitrogen supply piping to the Safety Injection Tanks. If a control valve is open to raise SIT pressure at the time of an accident, the check valve would close to protect the nitrogen inventory/pressure in the SIT.

Constellation Energy (CCNPP Unit 1) IST Program SI-CSJ-04 These check valves are normally closed and only need to perform their active closure function in the event an accident requiring the SITs is initiated while nitrogen pressure to one of the SITs is being increased. (Additionally, these check valves are in series with O-N2-344 & O-N2-347.) Since this is a relatively infrequent and short duration evolution affecting only one SIT at a time, testing these check valves quarterly would significantly increase the time during which the plant is dependent upon their active closure function.

The volume and mass of nitrogen contained in each SIT is substantial. Even if the test connection were used, a significant leak rate through one of these check valves would be required for a long period of time in order to see a verifiable effect of SIT pressure. This would require breaching the containment pressure boundary for a long period of time. Alternatively, the leak rate could be determined using one of two methods. First, a leak rate monitor may be installed at the test connection. However, installing a leak rate monitor is acknowledged in NUREG-1482, Rev. 1, as a basis for deferring testing. Alternatively, a pressure gauge may be installed at the test connection and the rate at which the isolated piping pressurizes measured, as is done in the cold shutdown test.

However, installing a pressure gauge and performing such a test quarterly would significantly increase the amount of time during which the administratively controlled upstream containment isolation control valves (1/2-CVC-612-CV, 1/2-CVC-622-CV, 1/2-CVC-632-CV, and 1/2-CVC-642-CV) are open (as well as the capped test connection).

Opening the capped test connection and the associated manual valve which form part of the containment boundary but not part of the penetration flow path is not considered to be prudent. Technical Specification 3.6.3 allows that "penetration flow paths may be unisolated intermittently under administrative controls." The Technical Specification Basis does not address what, if any, limitations there are on the reasons for using this allowance.

However, it is considered consistent with the intent of this Technical Specification that the reasons for opening a valve under administrative controls should be to accomplish a function which is necessary for continued safe operation. This logic is supported by the use of the phrase "penetration flow path" instead of a more generic term such as containment boundary. Performing a test in the manner described would breach the containment boundary by opening valves which are not part of the penetration flow path. Therefore, Calvert Cliffs considers such a test to be contrary to the intent of the Technical Specification.

Additionally, more frequent testing would require increased personnel radiation exposure and present more frequent situations in which potential component failure or human error could affect the operability of a SIT and place the plant in a very short-duration action statement. This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

These valves will be exercised in the open and closed directions during cold shutdowns in accordance with OM Code paragraph ISTC-3522.

ConstellationEnergy (CCNPP Unit 1) IST Program SI-CSJ-05 Not Approved Component ID Class Cat. System Label 1-SI-313 2 C SI Containment Spray Discharge Check Valve 1-SI-323 2 C SI Containment Spray Discharge Check Valve FUNCTION:

These valves open to provide flow paths from the containment spray pumps to the containment spray headers.

TEST REQUIREMENT:

OM Code paragraph ISTC-351 0 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

These are simple check valves with no means of external position indication or operation. During power operation, the only way to full-stroke exercise these check valves open would be to operate the containment spray pumps discharging into the containment spray headers. This is not acceptable because it would result in spraying contaminated borated water into the containment and result in equipment contamination and damage.

The containment spray pump discharge bypass lines do not allow sufficient flow to full-stroke these valves during quarterly pump testing. Establishing a flow path requires that 1/2-SI-459 be opened. Valve 1/2-SI-459 is maintained closed (and is leak-tested every two years) to ensure no highly contaminated fluid will reach the RWT following entry into recirculation mode subsequent to a LOCA involving partial fuel failure. This ensures Calvert Cliffs meets the applicable assumptions in the Off-Site Boundary Dose and Control Room Habitability Studies.

Opening these valves during power operation violates the parameters of these studies. A dedicated Operator could be stationed at the valves, which are located in the Radiologically Controlled Area, while they are open.

However, given the additional radiation exposure that would be incurred by stationing a dedicated Operator at the valves during a part-stroke exercise, this is not considered to be practical. Therefore, quarterly part-stroke testing is not considered practical.

The containment spray pumps and the associated discharge check valves can be full-flow tested by substituting the containment spray pumps for the low-pressure safety injection pumps into the shutdown cooling lineup after sufficient decay heat has been removed. Therefore, these check valves are full-stroke exercised open during cold shutdown periods (depending on plant conditions) and during every refueling outage when the containment spray pumps' high flow rate test is performed.

This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

These normally-closed valves remain closed to isolate the 12 (22) saltwater discharge headers from the 11 (21) saltwater supply headers, at the Emergency Overboard discharge flow path cross-connects between the Service Water Heat Exchangers, Component Cooling Heat Exchangers, and ECCS Pump Room Air Coolers, to ensure the normal cooling water flow is maintained to the components and heat exchangers cooled by the 11 (21) saltwater trains. They are opened when cooling is required in the emergency overboard lineup.

TEST REQUIREMENT:

OM Code paragraph ISTC-351 0 requires Active Category A and B valves and Category C check valves to be exercised nominally every 3 months during operation at power to the position(s) required to fulfill its function(s),

except as provided by ISTC-3520, ISTC-3540, ISTC-3550, ISTC-3570, ISTC-5221 and 5222.

BASIS:

Each pair of valves is operated from a single handswitch and neither valve in each pair can be individually opened without placing the other valve in an abnormal configuration (e.g. securing air to the actuator or installing jumpers in a valve control circuit). Exercising any of these valve pairs during plant operation at power would allow significant bypass flow between the headers at the respective heat exchanger or cooler. Depending on saltwater header pressure, hot discharge flow from the 12 (22) header could be introduced into the 11 ( 21) supply header, or supply flow from the 11 (21) header could bypass each respective heat exchanger or cooler and pass into the 12 (22) discharge header. In either case, flow between the saltwater headers would significantly degrade the heat removal capacity of the heat exchangers or coolers supplied by the 11 (21) saltwater headers.

Additionally, while these valves are open, the two saltwater headers are not independent. As a result, both saltwater headers are considered inoperable and the plant is placed in a short-duration action statement. Should any valve pair fail to re-close after being opened, the saltwater system would no longer remain capable of performing its safety function in view of the associated single failure requirements, thereby necessitating a plant shutdown and cooldown.

Partial opening of these valves presents the same risk as full opening, thus it is also not feasible during operation.

This is consistent with the position stated in NUREG-1482, Rev. 1, Paragraph 2.4.5.

ALTERNATE TESTING:

These valves will be full-stroke exercised and stroke timed in the open direction during cold shutdowns in accordance with OM Code paragraph ISTC-3521.
