HNP-IST-003 HNP IST Program - 3rd Interval

1.0 INTRODUCTION AND BACKGROUND

1.1 Introduction This document represents the Harris Nuclear Plant (HNP) Inservice Testing (IST)

Program for the third interval. It establishes testing and examination requirements to assess the operational readiness of certain Safety Class 1, 2, and 3 components important to nuclear safety. These requirements apply to:

pumps and valves required to perform a specific function in shutting down the reactor to the safe shutdown condition, in maintaining the safe shutdown condition, or in mitigating the consequences of an accident;

pressure relief devices that protect systems or portions of systems that perform one or more of these three functions; NOTE: HNP is licensed for safe shutdown at the hot standby condition. Pumps and valves required to achieve and maintain the cold shutdown condition are optionally included in the IST Program as augmented components. These augmented components will be tested in accordance with the IST Program to the extent practicable.

This IST Program provides compliance with the regulatory requirements identified in Section 1.2 (below), FSAR Section 3.9.6 and Technical Specification Surveillance Requirement 4.0.5.

1.2 Background Testing and examination of the components described above was controlled by the Inservice Inspection Program Requirements Manual (ISIPRM) for the second interval.

Revision of the ISIPRM for the third interval included relocating modules related to inservice testing into this IST Program. Separation of the inservice inspection and inservice testing requirements into different requirements manuals for the third inservice interval followed separation of the American Society of Mechanical Engineers (ASME)

Codes - ASME Section XI for inservice inspection and ASME OM Code for inservice testing.

1.3 Jurisdiction The jurisdiction of this IST Program covers individual components that have met all of the requirements of the construction code commencing at the time when the construction code requirements have been met, irrespective of the physical location.

When portions of systems or plants are completed at different times, the jurisdiction of this IST Program covers only those components on which all construction related to the components have been completed.

1-1 Revision 00 Revision 1-1

HNP-IST-003 HNP IST Program - 3rd Interval 2.0 BASIS FOR INSERVICE TESTING PROGRAM 2.1 Code of Federal Regulations Requirements The Code of Federal Regulations, Title 10, Part 50.55a (10CFR50.55a), paragraph (f)(5)(i) requires each licensee of pressurized water-cooled nuclear reactors to revise their inservice testing program to meet the requirements of 10CFR50.55a(f)(4)(ii). As a result, the inservice testing program must be revised at 120-month intervals to comply with the requirements of the latest edition and addenda of the Code incorporated by reference in 10CFR50.55a(b) 12 months before the start of the 120-month interval subject to the limitations and modifications listed in 10CFR50.55a(b)(3).

2.1.1 10CFR50.55a Limitations and Modifications Limitations and modifications from 10CFR50.55a(b)(3) are incorporated into this IST Program as described below.

2.1.1.1 10CFR50.55a(b)(3)(i) - NQA-1, "Nuclear Quality Assurance Requirements for Nuclear Facilities" This modification/limitation is incorporated into the IST Program by means of reference to HNP's quality assurance program. Specifically, paragraphs 4.4, 4.7.2, 4.8.3, and NGGM-PM-0007 implement these requirements.

2.1.1.2 10CFR50.55a(b)(3)(ii) - Motor-Operated Valve Testing HNP will maintain and implement motor-operated valve testing program to ensure motor-operated valves will continue to be capable of performing the design basis safety function. The HNP motor-operated valve testing program is governed by EGR-NGGC-0101 and EGR-NGGC-0203.

2.1.1.3 1 OCFR50.55a(b)(3)(iii) - reserved No action required.

2.1.1.4 10CFR50.55a(b)(3)(iv) - Implementation of a Check Valve Condition Monitoring Program All elements of this modification and limitation are incorporated into this IST Program. Specifically, procedure ISI-803 implements these requirements.

HNP-IST-003 HNP IST Program - 3rd Interval HNP-IST-003 HNP 1ST Program 3rd Interval 2.1.1.5 IOCFR50.55a(b)(3)(v) - Dynamic Restraints This modification does not apply to HNP because ASME Section XI or ASME OM Code is not used for testing/examination of dynamic restraints.

Dynamic restraints are not included in the scope of this IST Program.

The HNP dynamic restraint testing and examination program is governed by Technical Specifications 4.0.2, 4.0.5, 3/4.7.8 and PLP-1 06.

2.1.1.6 10CFR50.55a(b)(3)(vi) - Manual Valve Exercise Interval This modification changes the exercise frequency for manual valves from 5 years as allowed by the OM Code to 2 years. This modification is implemented by procedure ISI-801.

2.2 Inspection Interval Information 2.2.1 Inspection Interval Dates The first 120-month interval was originally expected to be applicable for the period of May 2, 1987 through and including May 1, 1997. However, the first interval was extended to February 2, 1998 as allowed by NUREG-1482, Section 3.3.1 and ASME Section XI, 1983 Edition, Article IWA-2400(c). The NRC was notified, by letter (reference 3.8 and 3.9), of the first interval extension.

The second 120-month interval was applicable from February 2, 1998 through and including May 1, 2007 The third 120-month interval is applicable from May 2, 2007 through and including May 1,2017.

2.2.2 Inservice Interval Requirements Inservice intervals are 10 years except they may be extended or decreased by as much as 1 year. Adjustments shall not cause successive intervals to be altered by more than 1 year from the original pattern of intervals.

In addition, for units that are out of service continuously for 6 months or more, the inservice interval during which the outage occurred may be extended for a period equivalent to the outage and the original pattern of intervals extended accordingly for successive intervals.

HNP-IST-003 HNP IST Program - 3rd Interval Attachment 5.1 - IST Pump Table Notes The following notes provide clarification to the method of testing applied to the associated pump and are included by reference in the Pump Listing column "Remarks".

1. Quarterly pump testing will be accomplished utilizing the small diameter recirculation line back to the CST. Full flow testing will be performed prior to plant cooldown.

2. This small centrifugal pump does not have bearings in the pump casing. The pump impeller is attached to the motor shaft. Therefore, vibration measurements will be taken on the inboard motor bearing housing in a plane approximately perpendicular to the rotating shaft in two orthogonal directions. In addition, vibration measurements will be taken in the axial direction on the motor thrust bearing. Ranges for vibration and hydraulic parameters will be in accordance with procedure ISI-800 for centrifugal pumps Ž600 rpm.

3. Any one of the three CCW pumps may function as an installed spare. One pump is normally running, the second is aligned as an automatic backup to the operating pump, and the third pump is electrically disconnected. In the event of a failure of the operating pump, the second (reserve) pump automatically starts upon detection of low CCW header pressure. The installed spare is electrically connected to the opposite emergency bus from the now operating (reserve) pump and placed in a standby reserve condition. The installed spare is required to be tested only when it is connected to the system.

4. This vertical centrifugal pump does not have bearings in the pump casing and does not fit the definition of a vertical line shaft pump. The pump impeller is attached to the motor shaft. Therefore, vibration measurements will be taken on each motor bearing housing in a plane approximately perpendicular to the rotating shaft in two orthogonal directions. In addition, vibration measurements will be taken in the axial direction on the motor thrust bearing. Ranges for vibration and hydraulic parameters will be in accordance with procedure ISI-800 forcentrifugal pumps Ž_600 rpm.

5. Pump differential pressure is calculated using pump bay level and discharge pressure. The bay level and discharge pressure will be measured after two minutes of operation at test conditions as stable as the system permits.

6. Any one of the three CSIPs may function as an installed spare. One pump is normally running, the second is aligned as a backup to the operating pump, and the third pump (normally "1C") is electrically disconnected. In the event of a failure of the operating pump, the installed spare is electrically connected to the opposite emergency bus from the now operating pump and placed in a standby reserve condition. The installed spare is required to be tested only when it is connected to the system.

HNP-IST-003 HNP IST Program Plan - 3nd Inteval Attachment 5.2 - Pump Relief Requests AF-PR-1 Component Description Flow Diagram Dwg Systei Pump Coor Group AF1A-SA MD Auxiliary Feedwater Pump "IA" 2165-S-544 M-5 3065 A AF1 B-SB MD Auxiliary Feedwater Pump "1B" 2165-S-544 M-8 3065 A AF1X-SAB TD Auxiliary Feedwater Pump 1X-SAB 2165-S-544 M-10 3065 B Code Test Requirements The full scale range of each analog instrument shall not be greater than three times the reference value [ISTB-3510(b)(1)].

Basis for Relief:

The permanently installed flow instrument which is utilized to conduct the quarterly pump tests of the two motor driven auxiliary feedwater pumps (AF1 A-SA and AF1 B-SB) has a calibrated full scale range which exceeds a factor of three times their reference values. The full scale range of the instrument, FI-2172, is 0-200 gpm while the reference value of each pump is 51 gpm. FI-2172 is installed in a common pump recirculation line which is shared by both the two motor driven AFW pumps and the single turbine driven AFW pump. The indicator is sized to accommodate the combined restricted flows of all three pumps simultaneously. Although the full scale range of FI-2172 does not comply with Code requirements, its accuracy of +/-1% of full scale exceeds that which is required.

Even though FI-2172 does not meet the Code requirement for range, it is capable of providing an indicated accuracy at the reference value that is superior to the minimum indicated accuracy that would be required by the Code. Based on the least accurate instrument that would theoretically be allowed by the Code, the minimum required indicated accuracy is +/-6%. (This fact is documented by NUREG-1482, paragraph 5.5.1.). The indicated accuracy of FI-2172, as derived based upon the current reference values, is as follows:

Reference value 51 gpm Full scale range = 200 gpm Instrument tolerance = +2 gpm (+/-1% x 200 gpm)

Therefore the indicated accuracy is:

+/-2 gpm / 51 gpm x 100% =--3.9%

As demonstrated, the indicated accuracy of FI-2172 is better than that which is theoretically allowed by the Code.

This relief request was numbered AF-PR1 during the previous ten year interval and was approved by the NRC by letter dated February 1, 1999 (TAC No. MA0815). Relief is requested for the third ten-year interval pursuant to 10CFR50.55a(3)(i) since the proposed alternative would provide an acceptable level of quality and safety to that of the applicable Code requirement.

Alternate Test The existing permanently installed pump instrument is acceptable because the indicated accuracy is less than or equal to +/-6% as calculated at the reference value. No alternate testing or instrumentation will be utilized.

Approval Status This relief request was approved for the second 10 year inspection interval and is being resubmitted to NRC for approval to use in the third 10 year inspection interval. It is not approved by the NRC at this time.

Basis for Relief Normally closed, full stroke open and closed exercising requires operating the motor driven auxiliary feedwater pumps and injecting relatively cold condensate water directly into the hot steam generators. The introduction of cold water into the hot steam generators during normal operation results in thermal shock to the feedwater piping and associated nozzles. Allowing excessive thermal transients on the feedwater piping and nozzles could lead to their premature failure due to thermally induced stress cracking. In addition, to test auxiliary feedwater during normal operation would require starting the auxiliary feedwater pumps which would have an adverse effect on steam generator water level control potentially causing a forced plant shutdown. Quarterly pump testing is done through the pump recirculation lines and the downstream flow control valves automatically closed so that the pumps are essentially isolated from each other and reverse flow closure of these pump discharge check valves cannot be verified until full auxiliary feedwater flow is injected into the Steam Generators.

Basis for Relief Normally throttled, the position of valves 1AF-1 9 and 1AF-34 is automatically modulated during pump operation to protect against run out conditions. Testing of these valves would require the use of control logic defeating methods, such as temporary jumpers. Defeating the control logic associated with these valves to facilitate testing would render them incapable of performing their modulating function should an auxiliary feedwater initiation signal occur during testing.

Basis for Relief Normally closed, full stroke open exercising requires operating the motor driven auxiliary feedwater pumps and injecting relatively cold condensate water directly into the hot steam generators. The introduction of cold water into the hot steam generators during normal operation results in thermal shock to the feedwater piping and associated nozzles.

In addition, to test auxiliary feedwater during normal operation would require starting the auxiliary feedwater pumps which would have an adverse effect on steam generator water level control potentially causing a forced plant shutdown.

Basis for Relief Normally closed, full stroke exercising open requires operating the turbine driven auxiliary feedwater pump and injecting relatively cold condensate water directly into the hot steam generators. The introduction of cold water into the hot steam generators during normal operation results in thermal shock to the feedwater piping and associated nozzles. Allowing excessive thermal transients on the feedwater piping and nozzles could lead to their premature failure due to thermally induced stress cracking. In addition, to test auxiliary feedwater during normal operation would require starting the auxiliary feedwater pumps which would have an adverse effect on steam generator water level control potentially causing a forced plant shutdown.

Part stroke exercising in the forward direction during normal operation would result in the same consequences as full flow exercising. The only source of steam to the steam driven turbine is from the main steam system. To operate the turbine requires that the steam generators be producing sufficient steam to drive the turbine. The control of steam generator water level when producing steam is much more critical than during the refilling process when the motor driven pumps are tested. To perform flow testing during steam production would have a significant impact on steam generator water level control on all three steam generators possibly resulting in a reactor trip. Additionally, full flow testing should be performed at a point when sufficient steam pressure has been established to minimize a delay in plant restart. (Valves 1AF-204, 205, and 206 are verified closed quarterly).

Code Test Requirements Check valves shall be exercised nominally every 3 months per the requirements of ISTC-351 0.

Basis for Relief These excess flow check valves are located oustide containment in instrument sensing lines. These valves are normally open by spring force and close with high flow from a downstream instrument line break. The upstream side of these check valves is open to containment atmosphere at negative pressure and does not have test connections. Closure verification of these valves requires installation of test equipment consisting of a pressure regulator, flowmeter, pressure gauge, air filter, additional tubing/fittings, and an instrument air source. Actual testing involves disconnection of the low side of the assocated pressure transmitter and capping it off. Upstream of this section of tubing, a flowmeter is installed at the calibration valve. This valve is downstream of the typical check to be tested. Upstream of the check valve, the regulator, gauge, and instrument air source is connected.

Air is flowed against the check valve, pressure measured, and check valve is verified shut by the flowmeter.

NUREG-1482, Section 4.1.6 states, "... The NRC has determined that the need to setup test equipment is adequate justification to defer backflow testing until a refueling outage....

Open verification testing of these check valves will be performed at the same frequency as the stroke close test frequency as allowed by ISTC-3522(a).

Code Test Requirements Check valves shall be exercised nominally every 3 months per the requirements of ISTC-3510.

Basis for Relief These vacuum breaker check valves are self-actuated and are located inside the primary reactor containment.

Due to their physical location, there is no practical means to verify the open and close capability on a 3 month frequency as required by ISTC-3510.

These valves are 24" swing type check valves with no pressure or position sensing accessories. The valve disk is normally held in the closed position by the force of two springs mounted on the valve pivot shaft. At a predetermined set pressure, an equilibrium exists where the seal area times set pressure are equal to and balanced against the spring when the valve is closed. When a differential across the valve causes a torque about the shaft greater than that produced by these forces, the valve will open as long as this force remains greater than the closing force produced by the two springs. When the flow and differential pressure drops to the extent that they produce less torque than the two springs, the valve will close.

The only practical method to verify the open and close capability is to manually exercise the valve disk through a complete cycle. The Containment Vacuum Relief System is not provided with the means to actuate these valves to the open or closed position with flow. Since, these valves are normally seated by spring pressure, the only practical method to verify the setpoint of the valves is to use a calibrated spring scale to measure the force required to unseat the disk.

Each of these activities would require entry into primary containment at power which is impractical. Containment entries during operational modes 1 through 4 are undesirable from a personal safety standpoint due to the high radiation environment and the high ambient temperatures affecting work conditions. Additionally, entry into containment during power operation is administratively controlled by a plant procedure with requirements to perform pre-entry airborne radioactivity and air quality samples, implementation of heat stress controls, control of materials, radiological controls, a containment closeout inspection and a local leakage rate test of the applicable entry hatch seals.

Testing during non-planned cold shutdown periods is also impractical due to the requirement to enter containment and the need to build scaffolding to access the valves. Additionally, in order to complete the testing of the subject valves, test equipment to verify the opening setpoint must be installed and subsequently removed.

Alternate Test (SC) Stroke close at (RO) refueling outage (SO) Stroke open at (RO) refueling outage (ref. ISTC-3522(c))

Basis for Relief 1CC-211 is normally open and 1 CC-250 and 1CC-298 are normally closed. Testing these valves quarterly during power operation and during cold shutdowns of short duration is not practical due to the interruption of cooling water flow to the RCPs required to align for the test configuration. These check valves are located inside primary containment serving as inboard containment isolation valves and are not provided with position indication. The only method available to verify reverse flow closure capability of these check valves is by interrupting their normal process functions and performing seat leakage testing. The test connections utilized to perform seat leakage testing are located inside containment. Therefore, it would require containment entry in order to verify their closure capability. Routine containment entry cannot be made quarterly during power operation due to high radiation levels and the potentially harsh environment inside primary containment.

Basis for Relief Normally open, these are the containment isolation and block valves located in the RCP thermal barrier and bearing oil cooler lines. Testing these valves quarterly during power operation and during cold shutdowns of short duration is not practical due to the interruption of cooling water flow to the RCPs. Failure for these valves to open subsequent to closure would result in a complete loss of cooling water flow to the RCPs. A loss of cooling water for more than a few minutes could result in extensive damage to the pumps and pump motors and potentially:;

cause a plant trip. Westinghouse Document 1B5710-100-07A states that cooling water must be provided to the pumps at all times when the RCS temperature is above 200 0 F. Plant procedures indicate that it is desireable to operate the pumps during cold shutdown and that at least one RCP be operating when RSC temperature is >

160 degrees F. Testing during cold shutdown is not practical since cooling water to the reactor coolant pump thermal barriers and motor bearings must be isolated to perfom the test. This would require all reactor coolant pumps to be stopped.

NUREG-1482, Section 3.1.1.4 indicates the need to stop reactor coolant pumps is adequate justification to defer testing to refuel outages.

Basis for Relief Normally open, this simple check valve is located in the discharge piping from the volume control tank (VCT) to the charging pump suction header. Reverse exercising this check valve quarterly during power operation would require isolation of the VCT inlet piping and RCP seal return piping, operation of RHR pump discharge to charging pump suction and monitoring for a VCT level increase. This is not practicable during normal operation due to pressurizer level control transients potentially resulting in a reactor trip.

Also, this test is not practicable during cold shutdown for the following reasons. Temporary jumpers must be installed to simulate closure of loop suction valves 1RH-1 (1RH-39) and 1RH-2 (1 RH-40) in order to open RHR/CS cross-connect valve 1 RH-25 (1 RH-63) and provide flow through the subject check valves. Installation of these jumpers requires one train of RHR to be declared inoperable. While in this alignment, the RCS would have to be vented to keep RHR pump discharge pressure below the design pressure of charging pump suction piping.

Per NRC Information Notice 95-35, plant shutdown risk management procedures requires both loops of RHR to be operable in cold shutdown with RCS pressure less than 130.psig.

Open verification testing of this check valve will be performed at the same frequency as the stroke close test frequency as allowed by ISTC-3522(a).

Basis for Relief Normally closed, this check valve is located in the supply line from the RWST to the charging pump's suction header. Verification of forward flow operability quarterly during power operation would require injecting RWST water into the RCS. Aligning the RWST to the charging pump's suction header would cause injection of the highly borated solution contained in the RWST into the RCS via the charging pumps. This RCS injection from the RWST would result in severe power fluctuations and possible plant shutdown. Partial stroke exercising this check valve quarterly during normal operation is prevented for the same reasons as full flow exercising. Full flow exercising these valves at cold shutdown could result in low-temperature overpressurization of the RCS due to the lack of sufficient expansion volume necessary to establish the design accident flow rate.

Basis for Relief Normally open, exercising these valves closed quarterly during normal operation would require interrupting seal water flow to the RCP shaft seals. The interruption of seal water flow to the RCP shaft seals is not practical during power operation due to the potential of causing damage to the seals. Exercising these valves closed during cold shutdowns, if the RCS were pressurized, or filled above the seal package level, could allow the RCS to flow through the pump seals. This flow could introduce particulates suspended in the RCS into the pump seals which would accelerate seal wear potentially resulting in premature failure. Testing these valves at refueling outages when the RCS drained to a level below the RCP seal packages would preclude damage to the seals.

Basis for Relief These normally closed system isolation valves are located in the boric acid gravity feed line to the charging/safety injection pumps and may be used to supply water directly from the Boric Acid Tank to the suction of the CSIPs via gravity feed, if'the Boric Acid Pumps are not operable. This flow path is optionally required to be operable per T.S.3.1.2.1 in Modes 4, 5 and 6.

Opening manual isolation valve 1CS-526 during normal operation would negate redundent isolation between charging pump suction and boric acid subsystem. The surveillances 4.1.2.1 .a and b, listed in T.S.3.1.2.1, are to check BA temp greater than 65 degrees every 7 days, and a valve line-up and flowpath check every 31 days.

There is no mention of a flow verification for the gravity flow path. During the outage, credit is not taken for 1CS-526 flowpath according to OMP-003. OST-1864 is a mode 6 defueled test, so by default it can be nothing less than an 18 month interval test. Supplying an operable CSIP during plant operation with a three inch diameter pipe supply is considered an unnecessary challenge to the component based on the previous items listed. In addition, the boric acidsubsystem pressure is not sufficient to open check valve 1CS-525 during normal and cold shutdown operation because normal charging pump suction pressure is greater than boric acid tank head .

pressure. Additionally, the piping line associated with 1CS-526 is a three inch line. The normal supply line to the suction side of the CSIP is a six inch diameter pipe.

Close verification testing of this check valve will be performed at the same frequency as the stroke close test frequency as allowed by ISTC-3522(a).

Basis for Relief Normally closed, these simple check valves are located in the supply lines from the RHR heat exchangers to the charging pump suction header and are utilized during the recirculation phase of emergency core cooling.

Forward exercising these check valves quarterly would require starting the associated RHR pump, opening upstream power operated valves 1 RH-25 and 1RH-63, and establishing flow through the RHR heat exchangers from the RWST to the charging pump suction header. This is not possible during power operation. This flow path would not only upset the normal charging and letdown flow rates but would also result in severe power fluctuations and plant shutdown due to the injection of the highly borated contents of the RWST into the RCS via the charging pumps. Partial exercising these check valves to the open position would result in the same consequences as full exercising. Also, forward exercising these check valves during cold shutdown is not possible for the followingreasons. Temporary jumpers must be installed to simulate closure of loop suction valves 1RH-1 (1 RH-39) anhd 1RH-2 (1 RH-40) in order to open RHR/CS cross-connect valve 1RH-25 (1 RH-63) and provide flow through the subject check valves. Installation of these jumpers requires one train of RHR to be declared inoperable. While in this alignment, the RCS would have to be vented to keep RHR pump discharge pressure below the design pressure of charging pump suction piping. Per NRC Information Notice 95-35, plant shutdown risk management procedures requires both loops of RHR to be operable in cold shutdown with RCS pressure less than 130 psig.

The system piping containing these valves has no design provisions (such as test connections) to facilitate reverse exercising. The valves do communicate with static pressure from the VCT, however, test connections are not provided for differential pressure measurement between the check valves and the upstream normally closed power operated valves. Reverse flow closure capability is best able to be verified when the charging pumps can be removed from service and an abnormal RHR system alignment can be established.

Stroke close (SC) testing will be performed at the same frequency as allowed by ISTC-3522(a).

Basis for Relief Normally open/closed, these charging pump discharge check valves cannot be verified for full flow operability quarterly during normal operation. Normal charging flow is automatically controlled by downstream flow control valve (1CS-231) in response to RCS operating conditions. Injecting full flow into the RCS quarterly during normal operation would require realigning the flow through safety injection lines. This flow would cause an increase in reactor coolant pressure because letdown capacity is less than safety injection capacity. This is considered an ESF actuation which is prohibited by normal operations. Full flow exercising these valves at cold shutdown could result in low-temperature overpressurization of the RCS due to the lack of sufficient expansion volume necessary to establish the design accident flow rate.

Code Test Requirements Active Category B valves shall be exercised nominally every 3 months per the requirements of ISTC-351 0.

Basis for Relief These motor operated valves isolate the containment sumps from the containment spray pumps suction and RWST. During normal plant operation, these valves are closed and the containment sumps are maintained dry to prevent seepage of borated water from the sump to the containment liner and causing corrosion.

The physical arrangement of containment spray piping is such that opening the isolation valves under static conditions will allow several gallons of water from the system high points to drain into the containment sumps.

There is no method to drain the sumps other than entering containment and using a temporary sump pump to remove the water.

Therefore, full stroke exercising these valves quarterly is not practicable due to the actions required to maintain the containment sumps dry. In addition, partial stroke exercising would result in the same consequences as full stoke exercising.

Check valves shall be exercised nominally every 3 months per the requirements of ISTC-351 0.

Basis for Relief Full exercising valves 1CT-1 1 and 1CT-1 2 during normal plant operation would require closing the upstream manual isolation valve to restrict migration of NaOH to the spray system piping. However, there would still be some migration of NaOH. In fact, exercising these valves at the normal frequency would result in 80%-85%

increase of NaOH in the Reactor Building Containment Spray System and ultimately in the RCS via the RWST and CVCS. Higher radiation levels in the reactor building due to radio-activated sodium is not conducive to sound ALARA and maintenance practices. Additionally, the valve control circuitry is not provided with partial stroke capability. No drains are available to rid the sodium hydroxide after each quarterly test. Additionally, if drains were available, plant personnel would be exposed to highly caustic fluids after each test which would present significant personnel hazard. Sodium hydroxide causes severe burns if it comes in contact with the skin. Test personnel would be required to don rubber gloves, boots and face shields. Additionally, these valves are in the 89-10 MOV Program which subjects these valves to a more scrutinized test than typical stroke timing as required by ISTC-3510.

In order to stroke close 1CT-62 and 1CT-65, valves 1CT-1 1 and 1CT-1 2 are required to be opened and a level change of the NaOH Tank is monitored. This test evolution poses the same issues as discussed above.

AR 92659 was written due to critical path time being lost due to poor refueling water clarity. The ensuing investigation documented that;

1) Sodium Hydroxide in-leakage into the RWST causes a pH increase in the Refueling Cavity. This pH shift is enough to favor formation of a cloudy, iron hydroxide colloidal suspension in the cavity. Potential downstream effects of the sodium hydroxide in-leakage into the RWST during the performance of OST-1 118 and 1119, such as causing iron to form a cloudy precipitate in the refueling cavity, was probably not considered significant during the design phase of the test,

2) A second AR, 97-04975 identified that the CSAT Sodium Hydroxide Concentration had fallen out of specification,

3) Performance of RST-206 on 10/20/02 identified that the CSAT Sodium Hydroxide concentration had dropped below the Technical Specification limit of 28% (NCR 74811). The actual results were 27.63 percent Hydroxide.

Considering that the CSAT should be a stagnant tank, and that Sodium Hydroxide at 28% is a strong base, which will not degrade with time, dilution by RWST as a result of OST 1118/1119 appears the only logical explanation.

A dilution of approximately 70 gallons of RWST water would decrease the concentration in the CSAT about 0.5%. Note that hydroxide additions were made to the CSAT in 2000 and 2002 to bring the tank back to within Technical Specification limits,

4) Refueling water clarity was not sufficient to support the Critical Path of the outage schedule. As a result, the Revision 0 Attachment 6.2-24

HNP-IST-003 HNP IST Program Plan - 3nd Inteval Attachment 6.2 - Deferred Test Justifications DTJ-CT-2 station may have incurred economic.loss due to additional time spent off line. Additional economic consequence as a result of additional filters required for the Tri-Nuke filtering units occurred,

5) There was also a radiological impact in that the additional use of filters to purify the refueling cavity water caused additional dose to be expended.

Basis for Relief Normally open, instrument air supplies a number of components inside containment which are dependent upon instrument air to remain operable for support of normal plant operation. Exercising this valve to the closed position quarterly during normal operation would deprive these components of their normal actuating air supply.

Since the largest majority of these components have no backup air supply, component realignment or a loss of sensing capability is likely to occur upon interruption of their air supply. Such components include RCP Seal Leak-off AOV(s), Letdown CIV(s), and Blowdown AOV(s), some of which are inboard isolation valves. Loss of operability or mispositioning of these components could result in operating transients and a possible forced plant shutdown. Instrument air is the backup pneumatic source for the RCS PORV accumulator tanks. Operation of the PORV(s) are required for SGTR.

Code Test Requirements Verify reverse flow closure capability nominally every 3 months per the requirements of OM-1 0, Para. 4.3.2.

Basis for Relief It is impractical to perform a full-stroke closure exercise of the subject check valves during power operation or during cold shutdowns. The 0.75 inch boundary check valves isolate the non-safety related instrument air supply lines to the safety related air accumulators for the containment vacuum relief system outside containment isolation valves 1CB-2 and 1CB-6.

The primary function of the vacuum relief system is to assure the structural integrity of the containment building as a result of an inadvertent actuation of the containment spray system which causes a partial vacuum inside containment. Makeup air from outside of the containment will flow in to containment when 1CB-2 and/or 1CB-6 open when containment pressure (vacuum) reaches a predetermined setpoint (-1.0 in w.g.).

The instrument air system provides air to butterfly valves 1CB-2 (TK 1A-SA) and 1CB-6 (1TK 1 B-SB) actuator accumulators. The butterfly valves (1 CB-2 and 1CB-6) fail-closed upon loss of instrument air and use the air accumulators for three strokes. Each of the instrument air supply lines to the accumulators contains two simple check valves in series with no intermediate test connections for individual valve closure verification. These valves provide isolation in the event of a failure of the non-safety related instrument air supply. Only one check valve is required in order to meet the safety class interface criteria of ANSI N18.2a-1 975 "Revision and Addendum to Nuclear Safety Criteria for the Design-of Stationary Pressurized Water Reactors" as referenced in the HNP FSAR. It is not practical to verify the full-stroke closure of these valves utilizing non-intrusive diagnostic methods due to their size. These valves will be stroke close tested as series pairs in accordance with ISTC-5223. Pair #1 will consist of valves 1 IA-786 & 1IA-787. Pair #2 will consist of valves 1 IA-788 and 1 IA-789.

Basis for Relief Normally open, full stroke closed exercising of these valves during normal operation isolates one line of steam flow to the turbine. Isolation of a main steam header would cause a severe pressure transient in the associated main steam line possibly resulting in a forced plant shutdown. Additionally, closure of an MSIV, at power, could potentially result in challenging the set point of the main steam relief valves causing inadvertent lifting. Reducing power level to perform testing without causing a transient would significantly impact plant operations and power production. These valves are provided with partial stroke capability, however, it is not practicable to full or part-stroke exercise these valves to the closed position during normal plant operation "since even a part-stroke exercise increases the risk of valve closure when the unit is generating power" per NUREG-1482, Section 4.2.4.

Basis for Relief Normally closed, the PORVs are controlled by the Pressurizer Overpressure Protection System, which automatically opens two of the three valves at a preset pressure. At power, set pressures are established to limit undesirable opening of the spring-loaded pressurizer safety valves. The PORVs are relied upon during reactor startup and shutdown to protect the RCS from potential low temperature overpressurization transients. In the event of a steam generator tube rupture, the PORVs may be required to open for accident mitigation by providing a means for rapid manual depressurization of the RCS. Due to the high probability for the PORVs to stick in the open position or failure to provide a leak tight barrier when closed, quarterly exercising during power operation is not practical. In accordance with Generic Letter 90-06, and the guidelines provided in NUREG-1482, Section 4.4.1, these valves will be tested on the way to cold shutdown during Modes 3 or 4, prior to LTOPS operation in Mode 5 or 6.

Basis for Relief These hydraulic assisted pilot operated valves were installed subsequent to the TMI accident, and serve as the RCS high point vent valves. Their intended function is to provide reactor head venting capabilities during a natural circulation cool-down evolution. The valves are routinely used during cold shutdown to provide a path for RCS venting.

Technical Specification 3.4.11 requires that one vent path from the reactor pressure vessel head and one vent path from the pressurizer be operable and. closed during operation. Testing of these valves quarterly during power operation, with subsequent failure in the open position, could result in uncontrolled blowdown of RCS inventory to the pressurizer relief tank or containment atmosphere should the downstream block valves inadvertently open or experience excessive leakage. Experience of this condition precipitated NLS-87-247 on 11/23/1987 and susequent License Ammendment NPF-63 #4 to remove the quaterly test requirements from T.S.3.4.1 1.

Tank 1C-SB Code Test Requirements Check valves shall be exercised nominally every 3 months per the requirements of ISTC-351 0.

Basis for Relief Normally open/closed, these simple check valves are located in the normal instrument air and nitrogen supply lines to the actuating air accumulators serving the two safety related PORVs, both of which are inside primary containment. The valves are not provided with remote position indication. To verify reverse flow closure capability of these check valves would require isolating and the depressurization of the instrument air and nitrogen supply headers for an extended period of time, and performing an accumulator pressure decay test. This test activity would require containment entry in order to verify Valve closure. Routine containment entry cannot be made quarterly during power operation due to high radiation levels and the potentially harsh environment inside primary containment. The reverse closure test is not practical during cold shutdowns since the PORVs are required to be available during cold shutdowns to prevent low temperature overpressurization of the RCS.

(OV) Open verification testing will be performed at the same frequency as (SC) testing as allowed by ISTC-3522(a).

Code Test Requirements Active Category A valves shall be exercised nominally every 3 months per the requirements of ISTC-3510.

Basis for Relief Normally closed, these RCS pressure isolation valves are located in the RHR pumps suction supply lines from the RCS hot legs. Exercising these valves quarterly during power operation is not possible due to the presence of interlocks which prevent their opening unless RCS pressure has been reduced to below 363 psig. This design feature prevents inadvertent overpressurization of the associated train of RHR. Defeating these interlocks to facilitate testing, with subsequent seat leakage of the inline valve, could lead to an inter-system LOCA by exposing the low pressure RHR system to the high pressure reactor coolant system. Partial valve exercising is precluded for the same reasons as full stroke exercising.,

Basis for Relief Normally closed, this motor operated valve serves as the second high pressure boundary barrier between the RCS and the low pressure piping of the Residual Heat Removal System. The valve is placed in the open position when switching from the cold leg to hot leg recirculation mode of safety injection. To prevent opening during normal operation the valve is electrically disconnected per Tech. Spec. 4.5.2.8 and administratively maintained closed. Exercising this valve quarterly during normal operation could cause overpressurization of the RHR System piping and result in an inter-system LOCA condition. The control circuitry associated with this valve is not provided with partial stroke capability. Even if possible, partial stroke exercising would result in the same consequences as full exercising.

Basis for Relief Normally open/closed, this check valve is located inside primary containment serving as inboard containment isolation valve for the safety injection (SI) accumulator fill line. It is not provided with position indication. Stroke open verification of this check valve requires feed and bleed of the SI accumulators and monitoring for a level increase or installation of non-intrusive flow instumentation to verify flow.

Testing using the SI accumulator feed and bleed method is not practical during normal operation because it would require unnecessary cycling of equipment to obtain a detectable level increase (ref. NUREG-1482, Section 2.5.4).

NUREG-1482, Section 3.1.1 states, "...Check valves that can be stroked quarterly, but must be monitored by a non-intrusive technique to verify full stroke, may be fullstoke tested during cold shutdowns or refueling outages if another method of verifying full-stroke exists at these plant conditions ....

Basis for Relief Normally closed, full stroke exercise open of these valves during power operation would result in flow through the injection flow paths into the RCS hot legs when 1 SI-86 and 107 are opened, and into the RCS cold legs when 1S1-1, 1SI-2, and 1 SI-52 are opened. Aligning this flow path would allow the injection of relatively cold water, which has bypassed the regenerative heat exchanger, into the RCS potentially thermal shocking the injection piping and nozzles which could cause premature failure of these system components. Opening these valves would also allow an increase in charging/injection flow potentially causing reactivity, temperature, pressure, and pressurizer level control transients which could result in a reactor trip. At cold shutdown one charging pump remains in service per T.S. 3.5.3 when RCS temperature is <335 degrees F. Exercising.these valves to the open position during cold shutdown would allow substantial increased flow into the RCS when there is marginal expansion volume to accommodate the additional flow for the test period. This increased flow could cause a low temperature overpressure condition in the RCS. The control circuitry associated with this valve is not provided with partial stroke capability. Even if possible, partial stroke exercising would result in the same consequences as full exercising.

Basis for Relief These valves are normally closed. A proper backseat test involves pressurization of the piping downstream of each check valve by a high capacity external pressure source. Pressurization from the opposite safety train is not possible due to check valves on the pump discharge line upstream of the nearest crossover line. These discharge check valves would potentially mask a non-functional suction check valve. Performing this test during cold shutdown is considered burdensome without a commensurate increase in the level of valve reliability due to the necessity of utilizing temporary test equipment and the extent of the test boundary which could delay plant restart. Additionally, this test activity could impact the ability to maintain the plant at cold shutdown under normal conditions due to the necessity of having one train of RHR operating in the shutdown cooling mode. The only time that a high volume pressurization source to these valves exists, without impacting system operation, is during refueling outages when the refueling cavity is flooded and the plant is lined up on residual heat removal.

At this time the static head from the refueling cavity will exceed that of the RWST thereby providing a reverse differential pressure across 1SI-320 and 1SI-321. Monitoring of RWST level over a specified period of time will provide adequate demonstration of reverse flow closure capability.
