TABLE E-1 TMI UNIT #1 VALVES REQUIRING PERIODIC INSERVICE INSPECTION 1934 122 8 0 0 2 0 8 0 :r> 5

INSERVICE INSPECTION PROGRAM FOR VALVES AT TMI #1 I.

Scope and Objectives This attachment describes the inservice inspection program for Class 1, 2, and 3 valves in TMI-1.

The objective of this program is to provide assurance of the operational readiness of the valves during their service life.

II.

Identification of Class Boundaries The Class 1, 2, and 3 boundaries are established in accordance with the NRC Standard Review Plan Section 3.2.2 (November 24,1975), ANSI N 18.2A (1975) and Regulatory Guide 1.26, Revision 3.

The system boundaries are shown on ISI Drawings C-300-001-GN1 through C-300-(II 005-GN1 and C-300-008-GN1 through C-300-023-GN1.

III.

Applicable Code Editions and Addenda In accordance with 10 CFR 50, paragraph 50.55a(f), the applicable Code Section and Addenda are the 1974 Edition with Addenda through Summer 1975.

IV.

Period of Applicability In accordance with 10 CFR 50, paragraph 50.55a(g)(4)(iv), this program is applicable from September 1,1979 to April 2,1981.

V.

Inspection Program The inservice inspection program which is detailed in the attached Table E-1 will be carried out in accordance with ASME Section XI, 1974 Edition, with Addenda through Summer 1975.

Specific exceptions to the ASME Code Section XI requirements for selected components are identified in Table E-2 along with the basis for each exception requested. The valves have been categorized as defined in ASME Code Section XI, paragraph IWV-2110.

VI.

Revision to Valve Testing Program This submittal is written as the plant is presently constructed.

However, as a result of Unit 1 Restart Change Modification some physical changes will be made to the plant.

Therefore, upon comple-tion of these changes and before startup of the Unit a revision will be submitted. Future changes to the Unit's locked valve list will be included when a revision of this submittal is made for other reasons.

See Reouest for Relief, Table E-2 Roman Numeral IX I934 I24 SYMBOLS:

Symbols appear in the following columns of Table E-1:

CLASS - The ISI system classification of the portion of the system in which the valve is located.

CATEGORY - As defined in ASME Code,Section XI, Paragraph IWV-2110.

TYPE OF TEST T - Full stroke valve exercise and time measurement for power operated valves.

F - Functional check of valve operation.

P - Partial valve stroke exercise.

(Partial stroke times will not be measured)

L - Valve seat leak test.

N - None, see Note in parenthesis.

SP - Set point test.

FS - Fail safe test.

a - These check valves separate high and low pressure systems and they perform a pressure barrier function insuring that the low pressure system is not subjected to pressures which exceed their design limits.

A recent meeting (12-18-79) with the NRC suggested that an alternative to leak rate testing would be acceptable. Therefore, at this time the exact method of testing these valves will remain open.

However, test methods will be developed and a functional pressure isolation test will be performed before or during Unit 1 Restart.

L2 - Verify and record valve position before operations are performed and af ter operations are completed, and verify that valve is locked or sealed.

ASME Section XI, IWV-3700 prescribes "no regular testing requirements for Category E Valves".

However, safety related locked closed valves will be stroked at each refueling outage.

These locked closed valves are in alternate flow paths of cooling water of engineered safety systems or are locked closed valves in a cleanup system for containment atmosphere.

E - Verify and record valve position before operations are performed and after operations are completed, and verify that valve is locked or sealed.

TEST FREQUENCY lh k

Q - Quarterly test frequency.

C - Cold shutdown test frequency (when shutdown exceeds 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> and more than 92 days have elaosed since test was performed during last previous shutdown period). This testing will continue until complete or the plant is ready to return to power.

Completion of all valve testing will not be a prerequisite to return to power. Any testing not complete at one cold shutdown will be performed at subsequent cold shutdowns.

(This is per a NRC staff position presented at meeting on October 18, 1978.)

R - Refueling outage test frequency.

F - Tests of valves are distributed over a 5 year period per ASME Section XI, paragraph IWV-3510(a).

ASME Code Section XI Requirement From Which Relief is Requested Relief is requested from paragraph IWV-3410(b)(1) which states that if only limited operation is practical during plant operation the valve shall be part-stroke exercised during plant operation and full-stroked during each cold shutdown.

3.

Basis for Requesting Relief All of the above listed valves are not designed with a part-stroke capability and any error in the frequent part-stroke testing of the valve could jeopardize the continued safe operation of the plant.

DH-V1 and DH-V2 are in the decay heat outlet line and part-stroking them could overpressurize downstream piping.

See NRC letter to 3934 158 Met-Ed dated November 17, 1976, Enclosure 2, paragraph 3.

DH-V6A/B isolates the Reactor Building Sump from the Decay Heat System and if DH-V6A or B failed in the open position during the cycling test this would cause the loss of the respective Decay Heat Pump and Cooler. This would put the plant in an unsafe condition.

See NRC letter to Met-Ed dated Novebmer 17, 1976,, paragraph 1.

MU-V12 isolates the Make-up Tank from the suction of the Make-up Pumps.

Part-stroking this valve during normal plant operation would jeopardize the continued operation of the running Make-up Pump if this valve completely closed due to valve operator mal-function.

Likewise, part-stroking MU-V20 would jeopardize the continued operation of the Reactor Coolant Pumps, since this valve supplies seal injection water to the Reactor Coolant Pumps.

RC-V3 is the block valve for the pressurizer spray line.

Part-stroking RC-V3 during normal operation would jeopardize the ability to spray the pressurizer and reduce pressure if RC-V3 stuck closed.

RC-V4 will not be part-stroked during normal plant operation in that downstream Decay Heat Piping may be overpressurized by the Reactor Coolant System pressure.

See NRC letter to Met-Ed cated November 17, 1976, Enclosure 2, paragraph 3.

The testing of EF-V4 and EF-V5 will introduce river water, silt and corrosives into the suction piping of the three Emergency Feedwater Pumps. This is unacceptable from a chemistry control standpoint for normal operations.

In order to flush the river water the suction valves of the Emergency Feedwater Pumps must be closed while perfonning the flushing operation. This would render the Emergency Feedwater Pumps inoperable during the flushing operation. Also, these valves are chained and locked shut and the breakers for these valves are open at the 480 volt power supply.

Essentially this means that these valves are not normally power activated.

MS-V13A/B and MS-V10A/B function to supply steam from the Steam Generators to the Turbine Driven Emergency Feedwater Pump (gF-P1).

MS-V13A/B functions to supply steam at or above Tavq of 525 F.

MS-V10A/BisalargervgiveandbydesignsuppliessteamtoEF-P1 at or below Tavg of 200 F.

To preclude the possibility of over-speeding and tripping EF-P1 (due to a sudden inrush of a large quantity of high pressure steam) MS-V10A/B will only be tested at cold shutdowns.

MS-V2A and B isolate the six turbine bypass valves. MS-V2A isolates three turbine bypass valves and likewise MS-V2B isolates the remaining three turbine bypass valves.

Technical Specification Number 3.4.1 requires four of the six turbine bypass valves to be operable.

If MS-V2A/B stuck closed during a quarterly test this would limit the ability of the plant to cooldown. Normal cooldown decay heat removal is by the steam generator through MS-V2A/B to the turbine bypass valves and then to the condenser.

ASME Code Section XI Requirement From Which Relief is Requested Relief is requested from paragraph IWV-3520(b) which states that if only limited operation is practical during plant operation the check valve shall be part-stroke exercised during plant operation and full-stroked during each cold shutdown.

3.

Basis for Requesting Relief During normal reactor operation the Reactor Coolant System is at a much higher pressure than the Core Flooding System and Decay Heat System; therefore, it is not possible to exercise CF-V4A/B, CF-V5A/B, DH-V22A/B and RC-V23.

See NRC letter to Met-Ed dated November 17, 1976, Enclosure 2, paragraph 3.

Testing CF-V12A/B invcives changing the position of other valves (CF-V28A/B) that are listed in Operating Procedure Number 1101-3,

" Containment Integrity and Access Limits".

Per 1101-3 the position of CF-V28A/B may not be changed during normal reactor operation.

Due to the desigg restrictions on the number of thermal cycles (40 cycles at 40 F feedwater), the emergency feedwater nozzles can undergo it is prudent not to exercise EF-V12A/B by charging through the emergency feed header while in normal operation.

j C;34 160 4.

Alternative to ASME Code Section XI Requirement Each of the above valves except EF-V12A/B will be full-stroke exercised during plant cold shutdowns exceeding 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> in duration when more than 9 months have elapsed since the previous test.

C Outlet 2.

ASME Code Section XI Requirement From Which Relief is Requested Paragraph IWV-3520(b) states that normally closed check valves that cannot be operated during normal plant operation shall be full-stroke exercised during each cold shutdown.

In case of frequent cold shutdowns these valves need not be excercised more often than once every 9 months.

3.

Basis for Requesting Relief a.

Although MU-V1078 and MU-V94 are normally open during normal plant operation, the remainder of the above High Pressure Injection Check Valves cannot be enerated during normal operation or at each cold shutdown because o the limited number (40) of allowable thermal cycles on the high pressure injection nozzles.

b.

During the functional test of RR-V8A/B and RR-V9A/B/C/D river water, silt and corrosives are introduced into the Reactor Building Emergency Cooling Coils. After the test these cooling coils must be first drained and then flushed with Nuclear Service Closed Cooling Water.

The drain and flush water is drained to the Reactor Building Sump and this produces large quantities of water that must be processed through the liquid waste disposal system.

Therefore, per Technical Specification 4.5.2 these check valves will continue to be tested on a refueling frequency (approximately every 12 months) instead of every 9 months. 1934 161

4.

Alternative to ASME Code Section XI Requirements Each of these valves will be full-stroke exercised during each refueling shutdown.

IV Small Bore Air Operated Valve Stroke Times 1.

Valve Identification All Class 1, 2, and 3 air operated valves 2" and less are identified in Table E-1, TMI Number i Valves Requiring Periodic Inservice Inspection.

2.

ASME Code Section XI Requirement From Which Relief is Requested Paragraph IWV-3410(c)(2) which states that the stroke time for all power-operated valves shall be measured to the nearest second or 10%

of the maximum allowable stroke time, whichever is less whenever such a valve is full-stroke tested.

3.

Basis for Requesting Relief Air operated valves 2" and less have full-stroke times usually less than one second. Thus, the valve stroke time cannot effectively be measured using normal test equipment such as a stopwatch. Also it is considered impractical to reliably measure changes in valve stroke times for valves which stroke open or closed in less than one (1) second. For very short stroke times, the variation in measured stroke times can be a large fraction of the established

troke time limit. Thus it is not practical to meaningfully identify or evaluate the stroke time changes considering human reaction times and the normal timing equipment used.

4.

Alternative to ASME Code Section XI Requirements Air operated valves 2" and less will be tested to ensure their opera-tional readiness as required by Section XI; however, the valve full-stroke time will not be recorded for these valves.

ASME Code Section XI Requirement From Which Relief is Requested Relief is requested from paragraph IWV-3410(c)(2) which states that the stroke time for all power-operated valves shall be measured to the nearest second or 10% of the maximum allowable stroke time, which-ever is less, whenever such a valve is full-stroke tested.

3.

Basis for Requesting Relief These valves are temperature and pressure controlled valves whose operators depend on changes in temperature or flow / pressure to initiate valve operation or change in position.

There is no prac-tical way to determine exactly when a normally open control valve starts to close and during normal operation the valve may be only partially open which would not be a full-stroke test.

Thus, the time test results for these valves will not be repeatable even though the valve operates as required.

4.

Alternative to ASME Code Section XI Requirements Each of the control valves will be functionally tested on a quarterly basis to ensure they operate as required; however, the valve full-stroke time will not be recorded.

3.

Basis for Requesting Relief EF-V12A/B will be tested only when cold shutdown extends more than 31 days in order to minimize the introduction of highly oxygenated water into the Steam Generators from the Condensate Storage Tanks.

This oxygenated water will deteriorate the Steam Generators tubes due to stress corrosion if this test is performed more often than when cold shutdown extends more than 31 days.

3.

Basis for Requesting Relief EF-VllA/B and EF-V13 will be full stroke tested only when cold shutdown extends more than 31 days in order to minimize the introduction of highly oxygenated water into the Steam Generators from the Condensate Storage tanks. This oxygenated water may cause deter-ioration of the Steam Generators tubing due to corrosion if this test is performed more often than when cold shutdown extends more than 31 days.

4.

ASME Code Section XI Requirement From Which Relief is Requested Relief is requested from paragraph IWV-3410(b)(1) which states that nonnally closed valves that cannot be operated during normal plant operation shall be full-stroke exercised during each cold shutdown.

3.

Basis for Requesting Relief DH-V6A/B is located outside the Reactor Building and this valve isolates the Reactor Building Sump from the LPI and HPI systems.

-3 1934 164

The piping from the Reactor Building Sump to DH-V6A/B slopes toward DH-V6A/B.

The "A" side slopes 9 inches and is approx-imately 35 ft. in length and the "B" side slopes 5 inches and is approximately 21 f t. in length.

Therefore, if DH-V6A/B were cycled frequently, this would admit large amounts of corrosives and " dirty" water into the LPI/HPI systems.

4.

Alternatives to ASME Code Section XI Requirement DH-V6A/B will be stroke time tested at refueling outages.

ASME Code Section XI Requirement From Which Relief is Requested Relief is requested from paragraph IWV-3520(b) which states if only limited operation is practical during plant operation the check valve shall be part-stroke exercised during plant operation and full-stroked during each cold shutdown.

3.

Basis for Requesting Relief The full stroke of BS-V30A/B would require initiation of Reactor Building Spray. This would entail spraying the Reactor Building with borated water. The full stroke of EF-V3 would supply river water to the suction piping of the three Emergency feedwater Pumps.

This is not acceptable from a chemistry control standpoint during non-emergency operation.

  • b 3.

Basis for Requesting Relief Check Valves FW-V12 A and B are normally open during plant operations to provide feedwater flow to the steam generators.

However, there is no practical way to test the valves closed when feedwater flow stops or the plant is in cold shutdown.

4.

Alternative to ASME Code Section XI Requirements As discussed above, there are no safe, practical ways to test she installed check valves closed and no alternate plans to test the valves are considered feasible. 1934 166
