SEA-VE-009 REV. I PAGE 3 BACKGROUND 8. PURPOSE Generic Letter 89-10 requires all safety-related motor operated valves (MOVs) be demonstrated to be operable under their design basis differential pressure and flow conditions. This is best accomplished by performing a dynamic test, defined as an in-situ test under differential pressure (dP) and flow conditions.

For this dynamic test scope, the following definitions shall apply to a non-testable MOV:

a) an MOV that cannot be dynamically tested because of the impracticability aspects of such testing (safety implications, potential damage to equipment),

b) an MOV that cannot achieve 50X or more of its design basis dP (rising stem).

Where testing of an MOV under design basis is not practicable the following alternatives can be considered:

A reduced severity test, where testing is performed at the highest practical dP and/or flow, is permissible when existing plant configurations do not make it practicable to test the MOV under design basis conditions. Dynamic testing at less than 50M design basis is considered not to provide reliable data to predict MOV performance at design basis.

Prototype test data from an NOV in situ test under design basis conditions may be used to demonstrate the operability of an identical MOV. The prototype may be an MOV that has been in-situ tested at the same plant, a different power plant, or a test facility.

Prototype test data can be applied to an identical MOV in a parallel train even though it may be practicable to test that MOV as well. In this text, this approach will be called "similarity analysis", whereby within a group of identical/similar MOVs, a minimum of one MOV will be dynamically tested and its results, along with other comparison factors, be used to assess the capability of the other identical/similar MOVs.

The use of applying prototype test data must be properly justified, since it has been evidenced (Reference 3.2) that "apparently identical MOVs performed significantly different under high differential pressure and flow conditions."

Prototype test data can be applied to an identical MOV that is not practicable to test. Impracticability aspects include such considerations as safety implications of such a test, the potential damage of the MOV or other plant equipment, the violation of plant technical specifications or procedures, ALARA concerns, the test resulting in the injection of non-reactor grade water into the reactor coolant system, etc. These factors or a combination of these and other

SEA-VE-009 REV. 1 PAGE 4 safety factors must be considered when determining that testing the HOV under design basis conditions is impracticable.

The purpose of this study is thus:

To define the scope of HOVs that will require dynamic testing, considering:

a) HOVs that require design basis or reduced severity testing b) groupings of HOVs to be used in a similarity analysis

2. To define the scope of HOVs that will not be dynamically tested, including:

a) Non-testable HOVs as defined above b) Hotor Operated globe valves that have an open safety function only and flow under the valve seat c) HOVs which have excess design margin as shown by the calculated available valve factor INPUT/ASSUHPTIONS 2.1 Ref. 3.6 provided an initial categorization of HOVs, based on valve type and valve operating characteristics (maximum design basis differential pressure, excluding inadvertent operation).

2.2 Testing at less than 50X design basis differential pressure is considered not to provide reliable data to predict design basis performance for rising stem valves.

2.3 Grouping of valves within a category is based on structural and functional criteria (References 3.4 and 3.7). Grouping of valves should not be considered for gate valves larger than 4 inch or with pressures greater than 200 psig because these valves are regarded to be the most controversial with respect to valve factor and valve performance. The exception is the core spray injection valves, which must be grouped because of the significance in testing.

2.4 HOVs with excess design margin as evidenced by a calculated available valve factor of 1.0 or greater (gate valves) or 2.0 or greater (globe valves) may be excluded from dynamic testing.

2.5 Globe valves with only an open safety function and flow under the seat may be excluded from dynamic testing.

2.6 HOVs with design basis dP of zero are considered testable, where the static test is also the dynamic test.

METHOD The overall dynamic test scope was based on the following methodology:

4.1 The scope of Generic Letter 89-10 HOVs was taken from Ref.3.3.

4.2 The scope of non-testable HOVs was defined (Reference 3. 13).

4.3 Valves were categorized based on valve type and operating characteristics. The following hierarchy of categories was established (once an HOV is placed in a category, such as quarter Turn, it is not be included in any subsequent category, such as HOVs with dP < 50 psid):

(a) quarter Turn Valves (b) MOVs with dP < 200 psid and > 0 psid with diameter < 4 inch (c) HOVs with dP < 50 psid and > 0 psid (d) Globe Valves (e) Remaining HOVs

SEA-VE-009 REV. 1 PAGE 6 4.4 HOVs with design basis dP = 0 psid were placed in their own category.

4.5 MOVs that were considered excludable from dynamic testing were taken out of the above hierarchy of categories and placed into their own categories. There are two categories: (1) globe valves with only an open safety function and flow under the valve seat and (2) valves not requiring dynamic testing based on excess available design margin.

4-.4 MOV groupings within a category were organized based on functional and structural similarity, using design information from Reference 3.7 and 3.4.

4.5 Remaining HOVs are identified as testable. These valves are not grouped, with the exception of a unique grouping of Core Spray injection valves. These valves must be grouped because of the significance in testing.

DISCUSSION

5. 1 Dynamic Testing The dynamic testing of an HOV is intended to be a once and done design basis verification test. Periodic static testing and trending in accordance with Reference 3.8 and 3.9 shall be performed in order to verify that the HOV remains adequate for its intended safety function.

5.2 Initial Grouping of HOVs 5.2. 1 The initial grouping of HOVs considered structural and functional factors. The specific design parameters used for grouping can be found in the Exhibits and include:

~

Structural factors which identify the physical make-up of the MOV, including valve design and actuator design.

Functional factors which identify the functional/operational requirements of the MOV, including process parameters and other factors that affect thrust/operability requirements (i.e., valve/stem orientation) 5.2.2 A minimum of one MOV from each group should be tested under dynamic conditions (Note: for HOVs with design basis dP of zero, each HOV in the group shall be tested). Guidance in selecting the HOV to be dynamically tested can be found in Appendix K.

NOTE: Gate valves larger than 4 inch or with pressures greater than 200 psig are considered'o be the most controversial with respect to valve factor and valve performance. Therefore all valves within this category will be tested (unless the calculated available valve factor is > 1) if at all practicable.

0 SEA-VE-009 REV. 1 PAGE 7 5.3 Justification for Grouping HOVs 5.3. 1 MOV Categories The MOV categories were based on valve types (i.e., globe, butterfly) and valve operational requirements (i.e., MOVs with dP < 50 psid and > 0 psid). The basis .for categorizing by operational requirements is to give consideration of HOV performance under specified design basis pressures.

Performance of an MOV under low accident design basis pressures is considered less controversial (less .likely to fail) than that under more severe conditions.

5.3.2 MOV Groupings The dynamic test scope may consist of groupings within the MOV categories. The basis for grouping is to give consideration for applying prototype test data, as necessary. Use of prototype test data to justify functionality is an acceptable alternative to design basis testing.

The valves in a group are expected to be enveloped by the results of the dP test of the "parent" tested valve. The preferred candidate for testing within each group is provided in Appendix K.

5.4 Revisions to the Overall Dynamic Test Scope The overall dynamic test scope may be affected because of additions or deletions to the Generic Letter 89-10 Scope, or because of changes affecting MOV categories or groupings. For example, certain activities (i.e., design modification) or situations may require that the baseline test be redone and/or that possibly retesting under dynamic conditions is needed. Reevaluation of the HOV category, grouping criteria, and similarity analysis may be required. Any changes which affect the overall dynamic test scope shall be documented in Appendix H of this study.

5.5 Non-Testable HOVs Systems Engineering has determined and provided the reason for MOVs that are considered non-testable due to impracticability aspects, such as safety implications, violation of tech specs, potential damage to equipment, etc. or due to the proposed testing resulting in the MOV achieving less than 50X of its design basis dP. Non-testable MOVs are listed in Appendix B; reasons are provided in the Addendum (later).

As part of Generic Letter 89-10 requirements, Pennsylvania Power &

Light intends to use the following alternatives to demonstrate MOV functionality under design basis for those MOVs Systems Engineering has justified non-testable:

SEA-VE-009 REV. 1 PAGE 8 a) The majority of non-testable HOVs will be justified using the EPRI HOV Predictive Performance Program computer methodology (expected availability in 1994) once evaluated for applicability to the methodology using guidelines provided by EPRI.

b) As part of the EPRI program, flow loop and valve testing has been performed to obtain test data for several unique designs (i.e, Anchor/Darling double disk gate valves) that are not modeled by the computer code. Evaluation of EPRI's prototype test data and its applicability to the similar type valves at SSES will be performed.

c) Evaluation of prototype test data from HOV testing at SSES, a different nuclear power plant, a test facility, or an industry-wide database will be performed, where available.

Factors similar to that used for similarity analysis (valve design, operating characteristics) will be examined in order to determine the applicability of the prototype test data.

d) Engineering analysis based upon design margin, safety significance and other factors, will be used where dynamic test data is not available.

5.6 Globe Valve Exclusions from Dynamic Testing Hotor Operated globe valves were also excluded from dynamic testing if two conditions were satisfied: 1) the NOV has an open safety function only, and 2) flow is under the valve seat. It is believed that such a configuration would help to assure the HOV performs its safety function, regardless of the dP condition. These HOVs would require static testing and evaluation of test results.

5.7 NOVs with Design Basis dP of Zero Static tests (wet or dry) will be used for evaluating functionality.

5.8 HOVs Tested without Diagnostics HOVs may still be tested under dynamic conditions even though is it determined that the test(s) cannot be monitored with diagnostics for some reason. If test conditions match design basis conditions, then the test is a valid design basis dynamic test.

5.9 Core Spray Injection Valves These NOVs are considered testable; however they are uniquely grouped. Testing requires core spray injection to the vessel and because of the significance of the evolution, it is PP8L's position to test two of the four in the group, one from each unit.

Some reasons that a valve may be determined to be non-testable:

a) Cannot be stroked with >50K of design dp and/or flow.

b) Test would create or result in severe plant consequences such as-

l. Require stroking at ILRT conditions

2. Require vessel injection of non-reactor grade water 3., Result in equipment damage

4. Require plant to be placed in unsafe condition

5. Require spray to suppression pool

6. Equipment would be inoperable and in LCO c) Performance of test would result in excess radiological exposures ALARA concerns

1. Inside Containment

2. Wingslab Area

3. High Radiation Areas d) Combination of Rad Levels & Excess Valve Factor. Not worth the expenditure of Radiation Exposure.

2. An alternate method, such as the EPRI HOV Predictive Performance Program, may have to be used to justify the HOV is adequate for its safety function.

VALVES NOT REQUIRING DYNAMIC TEST BASED ON EXCESS AVAILABLE MARGIN TOTAL MOVs: 38 TOTAL GROUPS: 0 MOVs in the Leakage Control System (LCS) have been excluded from testing.

All the LCS MOVs listed (prefix 139/239) have design margins (limiting valve factors) in excess of 1.0. In addition, it is proposed that the Leakage Control System be removed from the plant, in which case testing will not be necessary.

2. Globe valves HV-1(2)41F020 have been excluded from dynamic testing because they have a safety related limiting valve factor in excess of 2.0.

3. HV-1(2)51F040 (globe valves) and HV-1(2)51F049 (gate valves) have been excluded based on available margin in excess of 2.0 and 1.0 respectively.

l. All quarter turn HOVs shall be dynamically tested. One NOV from each group will be dynamically tested with diagnostics.

2. These HOVs are grouped for the intended use of a similarity analysis.

3. The grouping criteria used to establish valve grouping is found in Exhibit l.

Groups 2.3.4 are similar design butterfly valves. Based on preliminary modeling/scaling analysis perforemd by Kalsi Engineering, showing similarity between similar valves of different sizes, consideration should be given to re-evaluating the grouping (later).

4. These valves currently undergo surveillance testing. If the pressure and flow conditions during the surveillance test match design basis conditions, then the surveillance test is also a dynamic test. Per Reference 3. 14, the following valves qualify on that basis:

1. Each HOV in Appendix I-1 and I-2 shall be dynamically tested under design basis or reduced severity conditions and have its test results analyzed individually to justify the HOV is adequate for its safety function.

Comments on Dynamic Testing With Diagnostics: (Appendix I-1)

1. HV-151F028A/B, HV-251F028A/B, and HV-255F012 will be modified in the near future. Dynamic testing shall not be performed until after implementation of these modifications.

Comments on Dynamic Testing Without Diagnostics: (Appendix I-2)

1. HOVs will be dynamically tested without diagnostics because of inaccessibility during power operations or personnel exposure concerns.

Comments on Appendix I-3:

1. HV-152F005A/B and HV-252F005A/B are identified as testable and are uniquely grouped. Testing of these HOVs will necessitate Core Spray injections to the vessel. Because of the significance of the evolution, it is PPSL's position to test two of the four HOVs, one from each unit. The remaining two will be considered part of a grouping, where these HOVs are expected to be enveloped by the results of the tested valves.

2. Testing of two of the four HOVs will be performed with diagnostics.

3. Grouping criteria is found in Exhibit 6.

1. For butterfly valves, an example of a flow change direction device is an elbow in the pipeline. If the upstream or downstream flow change direction device is close (the length of several pipe diameters) to the subject valve, the resultant skewed velocity profile can affect the dynamic torque coefficient.

2. A flow change direction device is located close to every butterfly valve (

Reference:

the isometric drawing of the referenced pipeline),

excluding HV 21144A and HV 21144B.

3. Actual shaft orientation (retaining ring upstream/downstream) is not known, but should be a consideration in the similarity analysis.

4. For butterfly valve analysis, both dp and flow rate affect the stem torque.

5. HV 01224AI, HV 01224A2, HV 01224B1, HV 01224B2: Size and flowrate for the Al,Bl valves are different than for the A2,B2 valves. Because size and flowrate can affect butterfly valve analysis, these valves were not placed in a cumulative group. It is assumed at this time that one group is not "enveloped" by the other.

6. HV 2/11210A,B 5 HV 2/11215A,B valves were placed in a cumulative group. These valves have equivalent design structural identity but differ in flow and dp requirements. It is assumed that the valves which require lower dp and flow can be "enveloped" by the other valves which require higher dp and flow. A test of HV 2/11210A,B may prove HV 2/11215A,B will work but the reverse is not true because of the great difference in flow rate and dp. Thus these valves can be grouped only on that basis.

t

7. HV-08693A has been replaced by a newer design valve (RIE 92-0292).

The newer design valve is similar to the original design with the exception of an adaptor on the actuator shaft. (HV-08693B is the original design valve.)

1. The following HOVs are rising rotating valves: FV 149F019 and FV 249F019.

2. HV 150F045 8 HV 250F045  : The valve drawing for the unit 2 valve say SHB-000-5, but the as-installed actuator is the same as that of unit 1, SHB-0-25.

3. Several calculations (Reference 3.7) show DC motors with a specific supply voltage. It is now current practice to use available motor start torque instead of supply voltage to determine reduced voltage requirements.
