Introduction:

This report defines the Inservice Inspection Program for Class 1, 2, and 3 pressure retaining components for the period starting May 26, 1980 to C  ;

September 26, 1983 and Class 1, 2, and 3 pumps and valve testing for the period C t

starting September 26, 1978 to September 26, 1983. C -l This program has been developed as required by Section 50.55(a) of 10 CFR Part 50 i j following the guidance of the ASME Boiler Pressure Vessel Code Section XI,

" Rules for Inservice Inspection of Nuclear Power Plant Components". The ISI program (Inservice Inspection) will be controlled by the Fort Calhoun Station Unit #1 Technical Specifications.

j This Inservice Inspection Irogram is in compliance where possible, with the '

applicable requirements of Section XI, 1974 (Summer 1975 Addenda) of the ASME B & PV Code.

This program incorporates the results of previous inservice and pre-service inspections. It is the intent of the Licensee to continue to review and apply, as appropriate, changes in the' code which would improve the total Inservice Inspection Program, pursuant to 10 CFR 50.55(a).

! Part 1: Class 1, 2 and 3 Pressure Retaining Components a 1.1 Scope and Responsibility  ;

f e 1.1.1 The Piping and Instrument Drawings (P&ID's) in Appendix 1A identify that the system boundaries are always under review and are subject to change.

, 1.1.2 Class I and Class 2 components and the methods of exami- -

nation for each component are listed in Tables 1.1 and 1.2, i respectively. Class 3 components are those found on the P .

and ID's in Appendix 1A. The specific components to be l examined for each class shall be identified in the Fort  ;

, Calhoun Station Unit #1 Inservice Examination Plan by title I

and/or number. Class 3 components will be examined to the l extent required by IWD-2600. Exceptions to compliance with Tables IWB-2600 and IWC-2600 of Reference (1) are listed in Appendix 1B and Appendix IC, respectively.

1.2 Inspection Intervals 1.2.1 The inspection intervals for class 1, 2, and 3 components

! will be ten year intervals of service commencing on September 26, 1973. As indicated previously, this copy of A the program plan covers the first ten year interval, i.e., A September 26, 1973 to September 26, 1983. A '

?

! Ten year examination plans will describe the distribution of l examination within the inspection intervals in accordance with IWB-2400, IWC-2400, and IWD-2400 of Reference (1).

i- -

1.2.2 The inspection intervals for classes 1, 2, and 3 components may be extended by as much as one year to permit inspections to be concurrent with plant outages as permitted by IWA-2400 of reference (1).

1.3 Examination Catagories 1.3.1 Class I components as listed herein in Table 1, will be examined to the extent and frequency as required by Table IWB-2500 of Reference (1). Note: As a result of the 1980 Inservice Inspection the District has adopted a policy of examining the Reactor Coolant Pump Casing Studs every refuel-ing outage. This policy will be pursued rather than the code required "once per interval" inspection.

1.3.2 Class 2 components as listed herein in Table 2 will be examined to the extent and frequency as required by Table IUC-2500 of Reference (1).

1.3.3 Class 3 components as described in the ten year examination plan shall be examined to the extent and frequency as re-quired by Table IWD-2600 and IWD-2400 of reference (1). Open-ended portion of a system extending to the first shutoff valve and buried system components shall be exempted from pressure test and from inspection where accessibility is restricted.

1.4 Examination Methods 1.4.1 Class 1 and 2 components sF.all be examined by the required visual, surface and volumetric examinations. These examinations shall include one or a combination of the following methods: visual, (VT), liquid penetrant, (PT) magnetic particle, (MT), and radiographic examination in accordance with IWA-2200 of Reference (1). Ultrasonic examinations shall be performed in accordance with the following:

1.4.1.1 Ultrasonic examination of ferritic vessels with a wall thickness of 2 inches or greater shall be conducted in accordance with Appendix I of Reference (1).

1.4.1.2 Ultrasonic examinations of piping welds shall be conducted in accordance with article 5 of Re-ference (2) with the following exceptions: All ul*rasonic indications which produce a response greater than 50% of the reference level will be recorded, and all indications which produce a response greater than 100% of the reference level will be investigated and evaluated in accordance with Paragraph IWA-2232 of the Summer 1976 Addenda to Section XI. Indications of 20% of the reference

~ e x --w- ~g w

1.4.1.2 (Continued) .

level or greater which are interpreted to be a crack shall be identified and evaluated to the rules of Section IX. The ultrasonic examination of ferritic piping will be performed in accord-ance with the procedural requirements of Appendix

, I to the Summer 1975 addenda, ASME,Section XI.

1.4.1.3 The volumetric examinations of Class 2 circum-ferential pipe welds will conform to the addi-tional examination requirements of IE Circular 76-06, dated November 24, 1976 in that the examined area shall, where possible, cover a distance of approximately six times the pipe wall i

thickness (but not less than two inches and not to exceed 8 inches) on each side of the weld. This

additional examination area shall apply only to SI and CS systems piping.

1.4.2 Class 3 components shall be visually examined for leakage in i accordance with Article IWD-2000 of Reference (1).

1.5 Evaluation of Examination Results 1.5.1 Class 1 Components 1.5.1.1 The evaluation of the non-destructive examination results shall be in accordance with Article IWB-3000 of Reference (1). All indications shall be subject to comparison with previous data to j help in characterization and in determining origin.

1.5.2 Class 2 Components 1.5.2.1 The evaluation of nondestructive examination results shall be in accordance with Article IWB-3000 of Reference (1). All indication shall be subject to comparison with previous data to I

help in characterization and in determining origin.

1.5.3 Class 3 Components 1.5.3.1 The evaluation of the visual examination results shall be in accordance with Article IWA-5000 of Reference (1).

1.5.4 Indications which have been recorded in the preservices inspection or in a previcus inservice inspection which are not characterized as propagating flaws shall be accepted for continued service.

1.6.2 Scrface defects in class 1, 2 and 3 bolts, studs, nuts and ligaments may be removed by mechanical means when the re-moval of'a defect will not alter the basic configurations of the item. Bolts, studs and nuts that have defects that cannot be removed by mechanical means shall be replaced.

1.7 System Pressure Testing 1.7.1 General Requirements will

1.7.1.1 System Pressure test will be conducted in accord-ance with Article IWA-5000 of Reference (1).

1.7.1.2 Evaluation of any corroded area will be performed in accordance with Article IWA-5000 of Reference (1).

1.7.1.3 Repairs of corroded areas shall be performed in accordance with Section 1.6 of this program, i 1.7.2 Class 1 Components 1.7.2.1 Whenever the reactor coolant system is closed after it has been opened, the system will be leak tested in accordance with Article IWA-5000 and Article IWB-5000 of reference (1) and accordance with Fig. 2-1 and 2-2 of the Technical Specifi-Cations.

1.7.2.2 At or near the end of each inspection interval, a hydrostatic pressure test shall be performed on the reactor coolant system components. This test shall be conducted in accordance with the require-ments of Article IWA-5000 and IWB.5000 of Reference (1). Test temperature shall be in accordance with Figures 2-1 and 2-2 of the Technical Specifications.

1.7.3 Class 2 Components

[ 1.7.3.1 Pressure tests and visual examination of class 2 components will be performed in accordance with the guidelines of paragraph IWC-2412 of Reference (1).

The test pressure will be in accordance with the requirements of Article IWC-5000, Winter 1977 Addenda, in exception to the requirements of Refer-ence (1). The Technical Specification 2.1.1, limiting the number of cylces at 125% of design

! pressure to 10 for the secondary system (steam /

) feedwater) will be taken into consideration.

i Basis for Exception:

The majority of the Class 2 piping systems, sub-ject to the Section XI pressure testing, can be tested only when the plant is in a cold shutdown condition. While in this mode, there does not exist a means of heating the piping systems above ambient temperatures. Providing a means of heating long piping systems to 100 F is considered imprac-tical, within the meaning of 10 CFR 50.55a.

The minimum temperature requirement for performing a system hydrostatic pressure test was established to meet the requirements specified by fracture preventin5 criteria. Since the Fort Calhoun ferritic components' ambient room temperatures are suffi-ciently above brittle fracture temperatures (NDT typically 5 -20 F), heating the systems to 100 F is unnecessary. For the austenitic steel com-ponents, the NDT temperature is typically -325 F; far below any possible testing temperature. Again, heating the austenitic materials to 100*F is unnecessary.

Preservice hydrostatic tests were performed at ambient temperatures and it is the judgment of OPPD that hydrotesting at ambient temperatures is still acceptable.

1.7.4 Class 3 components 1.7.4.1 Class 3 components shall be pressure tested in accordance with article IWD-5000 of Reference (1).

1.8 Records and Reports Records and reports for this inspection made in accordance with this program shall be developed and maintained in accordance with Article IWA-6000 of Reference (1).

t APPENDIX IB EXCEPTIONS TO COMPLIANCE WITH TABLE IWB 2600 (CLASS 1 COMPONENTS) IN ASME BOILER AND PRESSURE VESSEL CODE, SECTION XI, SUMMER 1975 ADDENDA Item No. Exception B 1.4 The nozzle-to vessel welds cannot be 100% volumetrically examined from the 0.D. since the nozzle supports present an interference to currently available equipment. The nozzle- c.

to-vessel welds will be examined during the Reactor Vessel c Examination at the end of the interval. This examination c will be from the I.D. c B 2.2 The nozzle-to-shell weld and the inside radiused section of the surge line connection cannot be completely inspected volumetrically due to interference from the heater penetra-tions. The weld and inside radiused section will be exam-ined volumetrically to the extent possible and according to the schedule designated in the Examination Plan.

B 1.7-1.8 The volumetric total examined of closure studs may be limited per ASME code case N-307, according to NRC letter dated October 8, 1981, Clark to Jones, with attached SER.

B 2.5, 2.6, 2.7 These items are deleted in the inspection program since no bolting two inches and over is used.

B 3.4, 3.5, 3.6 This item has been deleted in the inspection program since no bolting two inches and over is used.

B 4.1 Safe end inspection in branch piping is deleted since branch piping has no safe ends.

B 4.2, 4.3, 4.4 This item has been deleted in the inspection program since no bolting 2 inches and over is used.

B 4.5 The primary piping is fabricated from centrifugally cast stainless steel pipe and cast stainless steel elbows.

Experience has shown that these uaterials and welds are not always amenable to ultrasonic examination. Techniques have been developed to sustantially overcome this problem. Volu-metric examination will be performed to the extent practical and according to the schedule designated in the Examination Plan. Should other specialized ultrasonic examination tech-niques become practical which are more effective, they will be incorporated in the Examination Plan. The ultrasonic examinations presently used will be supplemented by surface examinations where possible and where they will provide additional assurance that the integrity of thd primary pres-sure boundary is being maintained.

Appendix B (Continued) i .

B 5.4 The feasibility of volumetric examination has not yet been j determined. The exaaination will be performed if feasible . .

j and according to the schedule designated in the Examination i Plan. If extensive grinding is not required to prepare the surface of the pump casing adjacent to the weld for surface

{ examination, surface examination will be performed to supplement the volumetric examination.

B 5.6 There is currently'no known technique available to volu-metrically inspect the pump casing welds. Research is underway to overcome this problem. When proven techniques i are available, consideration will be given to the inclusion

! of these welds in the inspection program. An external surface examination of pump surfaces and welds is not con-sidered possible due to the roughness of the castings. An internal surface examination is impractical due to the high exposures that would be involved (the exam would require a minimum of 16 man-hours; the radiation levels can be i'

expected to be about SR/hr area and 7R/hr contact). The District's position is that a visual examination, performed 4

only if pump is dissembled for maintenance permitting such j

inspection, is judged to be adequate based upon design,.

fabrication and accessibility considerations.

B 5.7 The District's position is that a visual examination per-

{ formed only if pump is. dissembled for maintenance, permit-1 ting such inspection, is judged to be adequate based upon I

design, fabrication, and accessibility considerations. ,

B 6.1, 6.2, 6.3 This item has been deleted in the inspection program since no bolting two inches and over is used.

Examination Category C-D; Pressure-Retaining Bolting Exceeding 1-inch in Diameter An exception to the requirements of the Summer 1975 addenda of the Section XI Code is taken in regard to pressure-retaining bolting exceeding 1 inch in diameter. The District proposes to comply with the Summer 1976 addenda which modifies the bolting examination requirements to examine only the pressure-retaining bolting exceeding 2 inches in diameter. Since the Summer 1976 and all subsequent addenda to the Section XI Code have adopted the 2-inch diameter and greater examination requirement, the potential for failure and the consequences thereof appear to be of little concern.

l The code requirement of the Summer 1975 addenda is deemed to be impractical in relation to the level of safety achieved by performing the examination versus the manpower and monetary expenditures involved.

- APPENDIX 2A, INSERVICE INEPECTION OF PUM'PS 1'

. Discussion: All the pumps that . require an inservice tests for operational read-

, iness under the ASME B & PV Code,Section XI, Subsection IWP are listed below.

, i The inservice test parameters with te'st frequencies are tabulated for each pump.

The requested test exceptions and basis for each exception are given for the applicable parameters. ,

General: All the pumps listed are directly coupled to ' induction motor drivers; therefore, the. rotation speedsneed not be measured as prescribed in Subarticle 4400. Operating modes, as designated in this appendix, are as follows: Mode 1 -

Power Operation, Mode 2 - Hot Standby, Mode 3 Hot Shutdown, Mode 4 - Cold Shutdown, Mode 5 - Refueling Shutdown. .

Low Pressure Safety Injection Lumps SI-1A, B Class 2 Function: The LPSI pumps are available for safety injection of borated water into the reactor-coolant system following a LOCA and are used to remove residual heat for cold .<hutdowns.

Containment Spray Pumps SI-3A, B; C Class 2 ,

Function: The CS pumps are available to spray bcrated water into contain-ment following a LOCA. -

4 High Pressure Safety Injection Pumps SI-2A, B, C Class 2 4

- i Function: The HPSI pumps are available for safety injection of borated water into the reactor coolant system following a LOCA and are used to maintain the required water 1cvel in the safety injection tanks.

Operating Modes Subarticle Required For Test Parameter Frequency - Exceptions Testing Inlet Pressure Quarterly IWP-3100, 3400 1, 2, 3, 4 or 5 Differential Pressure Quarterly IWP-3100, 3400 1, 2, 3, 4 or 5 Vibration Amplitude Quarterly IWP-3400 1, 2, 3, 4 or 5 Lubrication Level Quarterly IWP-3400 1, 2, 3, 4 or 5 Bearing Temperature Yearly -

1, 2, 3, 4 or 5 Exceptions:

IWP-3100 Inlet and differential pressure measurement Basis: Inlet pressure for these tests will be determined by measuring the static head tank level.

Exceptions IWP-3400 Inlet pressure, differential pressure, vibration amplitude, and lubrication level will be measured on a quarterly schedule in lieu of monthly.

Basis: These pumps operate infrequently, and degradation-is more likely to result from usage than from periods of inactivity.

Monthly testing imposes a manpower hardship that is not commensurate with an increase in quality or safety. Testing all eight safety injection and containment spray pumps requires a total of 30 man-hours, and a licensed control room operator must be diverted from his primary responsibility of monitoring plaut equipment that is in operation.

Monthly testing subjects the persons conducting the test to adverse working conditions for extended periods of time.

Two men are required in the pump rooms for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> during C the test. The pump rooms typically have a radiation level of 10 m-rem /hr, resulting in a total exposure of 240 m-rem during the performance of each test. In addition, running the pumps represents a noise hazard and ambient temperatures of around 95 F with a relative humidity of near 100%.

During the test, each pump is unavailable to perform its safeguard function.

The safety injection and containment spray pumps are low-maintenance, low-failure rate items. The containment spray pumps SI-3A, B, and C operate essentially only during tests.

Maintenance records show these pumps have not required repair in eight years. The high pressure safety injection pumps SI-2A, B, and C are operated only during tests and to fill safety injection tanks during plant operation. Maintenance records show that one seal was replaced in eight years. The low pressure safety injection pumps operate during tests and as shutdown cooling pumps during cold shutdown periods. These pumps operate for considerably longer periods than the other pumps and maintenance records indicate that each pump required seal repair once. Thus, the plant maintenance records support the conclusions that the pumps are reliable and degradation is the result of use. Monthly testing requires that each pump be run eight (8) hours longer per year than quarterly testing would require.

Little or no additional increases in the level of safety or quality would accompany monthly testing because the pumps are historically reliable; redundant components exist for each pump; the pumps are lined up for their safety function and are essen-tially inactive during normal operations. Monthly tests further detract from a level of safety by subjecting workers to unnec-essary radiation exposure, harsh working conditions, and by increasing the wear on the pumps.

Charging Pumps CH- 1A, B, C Class 2 Function: The charging pumps are provided to return the purification flow to the reactor coolant system during plant steady state operations.

Discharge pressure will be measured on a monthly schedule to help determine possible pump degrada-tion.

Establishment of a reference value for flow rate.

Basis: There are many components or subsystems on the component cooling water system with several possible piping configurations.

Some of the components are critical elements to which the flow rate cannot arbitrarily be varied for the sake of running a pump test. Consequently, establishing a reference flow rate for a pump test on a periodic basis is impractical.

Lubricant level or pressure observation.

Basis: The pump bearings are cartridge type that have been re packed with the proper amount of grease and under normal conditions require no further attention for the life of the bearings.

Basis: System design does not permit direct measurement of inlet pressure. Varying river level and unknown accumulations of sand near the pump suction bell makes it impossible to determine the inlet pressure.

Differential pressure measurement.

Basis: Because of the inability to measure inlet pressure, differential pressure measurement is not possible.

Flow rate measurement.

Basis The system design does not provide an accurate indication of flow rate due to fouling by untreated river water.

Bearing temperature measurement.

Basis: All bearings arc inaccessible for temperature measure-ment. All are submerged in river water.

Discharge pressure vs. motor amperage.

Basis: To be performed in lieu of a differential pressure measurement. An acceptable motor amperage value will be deter-mined over a discharge pressure range of 26 through 40 psig.

Exception to IWP-3220 for All Pump Tests:

All test data shall be analyzed within 4 working days after completion of test.

Basis: An allowance of 4 working days to analyze test data instead of the 96 hour0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> requirement will allow greater flexibility in scheduling and performing the various tests. Special allow-ances for weekends and holidays will not have to be made in scheduling the tests. The safety related consequences of completing analysis within 4 working days rather than 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> is not considered to be great, since pump tests are performed on a quarterly basis.

APPENDIX 2B INSERVICE INSPECTION OF VALVES DISCUSSION: All valves that require an inserve test for operational readiness urder the ASME B&PV Code,Section XI, Subsection IWV, are listed below. All test parameters, frequencies, and test exceptions are tabulated with each valve.

It has been determined that there are no Category D valves at the Fort Calhoun Station, Unit No. I which are subject to the inservice inspection program.

All locked valves are given operational checks to verify position in accordance with Operating Instructions for the affected system, satisfying the requirements of Category E. ,

APPENDIX 2C JUSTIFICATION FOR EXCEPTION TO ASME SECTION XI CODE Category A Valves:

HCV-241 This valve is used for reactor coolant pump control bleed-off isolation. It cannot be stroked when the reactor coolant system is pressurized, because controlled bleed-off flow must be maintained to prevent damage to the reactor coolant pump seals. The valve cannot be partial-stroked because it is either fully open or fully closed.

HCV-206 This valve serves as penetration M-7, isolation. This valve cannot be. stroked when the reactor coolant system is pres-surized because controlled bleed-off flow must be maintained to prevent damage to the reactor coolant pump seal. The valve cannot be partially-stroked because it is either fully open or fully closed.

TCV-202 This valve is used for RCS loop 2A, letdown isolation and temperature regulation. Stroking of this valve quarterly during operation or at cold shutdowns would result in the terminati n of the charging _and letdown flows. This would also isolate the'boronmeter, process radiation monitor, and reactor coolant system purification process and would have the potential of causing a reactivity excursion. This valve cannot be partial-stroked because it is either fully open or fully closed.

HCV-204 The function of this valve is for containment penetration M-2, isolation'and letdown control. The stroking of this valve quarterly during operation or at cold shutdowns would result in termination of the charging and letdown flows.

This would also isolate the boronmeter, process radiation monitor, and reactor coolant system purifcation process.

In addition, the potential would exist for a reactivity excursion. This value cannot be partial-stroked because it is either fully open or fully closed.

SI-185 This valve is used to isolate the fill line for safety injec-

, tion tanks. It has been designated as Category A/E. The i valve is locked closed, and therefore is not subject to a stroke test. The valve will be leak-tested in accordance with Catedory A leak testing requirements.

HCV-2916, The function of these valves is to permit filling and drain 2936, ing of safety injection tanks. These valves cannot be 2956, stroked because doing so would cause level fluctuations in 2976 the safety injection tanks. The level of the safety injec-tion tanks is controlled by Technical Specifications, and stroking the valves may result in a violation of these Technical Specifications.

PCV-742A These valves are used for containment purge air isolation 742B and are closed during normal operations and cold shutdowns.

742C They are in the position required to fulfill their design 742D functions required to fulfill their design function and when open could provide a direct path for release of contaminants from containment. Therefore, stroking these valves may result in a potential release of contaminants. In addition, valves PCV-742A and 742C cannot be tested in the direction of their design function in accordance with IWV-3420 due to system configuration. The intent of subsection IWV of the Section XI code, to verify operational readiness is met since testing in the direction opposite to tae design function will result in a greater leakage than would be experienced in a test in the preferred direction.

HCV-746A This valve cannot be leak-tested in the direction of its design function in accordance with IWV-3420 due to system configuration. The intent of subsection IWV of the Section XI code, to verify operational readiness is met since test-ing in the direction opposite to the design function will result in a greater leakage than would be experienced in a test in the preferred direction.

HCV-881 The function of these valves is to isolate containment 882 hydrogen purge. Stroking at cold shutdown or quarterly intervals is not advisable, since doing so would provide a direct path for release of containments from the containment.

VA-280 The valves serve to isolate containment hydrogen purge and 289 are designated as Category A/E. They meet Category E criteria because they are locked closed. Cycling of these valves would provide a direct path for release of contam-inants from the containment during power operation or cold shutdown.

HCV-1559A The valves serve to isolate the containment demineralized 1559B water line at M-80. Cycling these valves would decrease i containment integrity. In addition, these valves are not required to be open during power operation.

I HCV-1560A These valves function to isolate the fill and makeup ,

l 1560B demineralized water lines to the pressurizer quench tank.

Cycling of these valves would decrease containment inte-grity. These valves are not required to be open during power operation.

HCV-2504A This valve serves to isolate the containment reactor coolant system sample link at penetration M-45. This valve cannot be leak-tested in the direction of its design function in accordance with IWV-3420 due to system configuration. The intent of subsection IWV of the Section XI code, to verify operational readiness is met since testing in the direction opposite to the design function will result in a greater leakage than would be experienced in a test in the pre- ,

ferred direction.

HCV-1749 This valve serves to isolate containment penetration M-74, compressed air penetration. This valve cannot be leak-tested in the direction of its design function in accordance with IWV-340 due to system configuration. The intent of subsection IWV of the Section XI code, to verify the opera-tional readiness, is met since testing in the direction opposite to the design function will result in a greater leakage than would be experienced in a test in the preferred direction.

HCV-425A These valves serve to isolate containment penetrations M-30 425B and M-53, component cooling system penetrations. Stroking 425C cannot be performed during cold shutdown or at quarterly 425D intervals because failure of these valves in the closed position would terminate cooling to safety injection tanks leakage coolers which would in turn have potential for resulting in hot fluid streams entering ion exchange resins of chemical volume control system, thereby causing damage.

These valves cannot be partial-stroked because they are either fully opened or fully closed.

HCV-438A These valves serve to isolate containment penetrations M-18, 438B and M-19, component cooling system penetrations. Stroke-438C testing cannot be performed at quarterly intervals or cold 438D shutdown because one or more reactor coolant pumps are in operation at all times and these pumps require lube oil and seal cooling. Stroking of these valves would terminate lube oil and seal cooling. These valves cannot be partial-stroked because they are either fully opened or fully closed.

HCV-46,'A These valves serve to isolate containment penetrations M-15, 467B and M-11, component cooling system penetrations. These 467C valves cannot be stroked quarterly because failure of the 467D valve during testing would render the nuclear detector well cooling units inoperable. Should the nuclear detector well cooling units fail, Technical Specification 2.13 could not be met. The valve cannot be partial-stroked because it is either fully opened or fully closed.

l HCV-2603B Containmemt isolation to penetrations M-42 and M-43, nitro-HCV-2604B gen gas header penetrations. These valves cannot be leak-tested in the direction of their design function in accor-dance with IWV-3420 due to system configuration. The intent of subsection IWV of the Section XI code, to verify the operational readiness, is met since testing in the direction opposite to the design function will result in a greater leakage than would be experienced in a test in the preferred direction.

PCV-1849 This valve serves to isolate instrument air pressure (via penetration M-7) to containment systems. Stroke-testing cannot be performed at cold shutdown or quarterly since instrument air must be available at all times during opera-tion and cold shutdown. The valve cannot be partial-stroked because it is either fully open or fully closed.

1 Category B Valves:

LCV-101-1 These valves serve to maintain pressurizer level control.

101-2 Stroke-testing cannot be performed during cold shutdown or quarterly because doing so would disrupt pressurizer level regulation capabilities. Upsetting pressurizer level regu-lation could result in RCS overpressurization. These valves cannot be partial-stroked during operation for the same reason.

LCV-218-2 This valve functions to' provide volume control tank level control. The valve cannot be stroke-tested in either cold shutdown or quarterly because doing so would terminate charging flow to the reactor coolant system and would have the potential for disrupting pressurizer level regulation.

Pressurizer level regulation disruption can lead to reactor coolant system overpressure transients. Partial stroke-testing cannot be performed because the valve is either fully closed or fully opened.

HCV-258 These valves serve to isolate concentration boric acid from 265 the charging pump suction header. These valves cannot be cycled during cold shutdown or quarterly because doing so would cause concentrated boric acid to be injected into the reactor coolant system via charging pump suction header gravity feedline. Boration of the primary system during normal operation would cause reactivity transients and pos-sibly shut down the plant and during cold shutdowns would delay startup. These valves cannot be partial-stroked for the same reason.

HCV-268 This valve serves to permit direct feed of concentrated boric acid solution to the charging pump suction header.

This valve cannot be stroke-tested during cold shutdown or quarterly because doing so would align concentrated boric acid storage to the charging pump suction header through the boric acid pumps. Boration of the primary system during normal operation would cause reactivity transients and pos-sibly shut down the plant and during cold shutdowns would delay startup. The valve cannot be partial-stroked for the same reason.

HCV-344 These valves serve as containment spray isolation. Stroke-345 testing during cold shutdown or quarterly is not advisable since the potential for spraying down the containment is increased. These valves represent the only boundary between the safety injection pump header and containment spray nozzles. The valves cannot be partial-stroked for the same reason.

HCV-347 These valves serve to isolate the shutdown cooling line.

348 They cannot be stroked quarterly because the operation of these valves is inhibited by dual pressure interlocks when the reactor coolant system pressure is greater than 265 psia.

Testing during cold shutdown is'not prudent since RCS heat removal must then be accomplished utilizing steam generator blowdown which provides marginal heat removal capability.

j i

HCV-400A, These valves serve to isolate component cooling to contain-B, C, & D ment air cooling and filtering units. They cannot be cycled 401A, quarterly because doing so would terminate component cooling B, C, & D to air cooling and filtering units in containment.

402A B, C, & D 403A B, C, & D HCV-1041A These valves serve to isolate the main steam headers. They 1042A cannot be tested quarterly during operation because doing so would isolate steam flow in the steam generators and result in a turbine and reactor trip. The valves cannot be partial-stroked because they are either fully opened or fully closed.

HCV-1041C These valves serve to provide a pathway from the steam gen-1042C erator to a steam dump and by pass valves in the event that the main steam isolation valves close. These valves are also used to pre-heat the turbine and related steam system during startup. Cycling of these valves on a quarterly basis during operation would cause the main steam isolation valves to close, causing the turbine to trip and resulting in a reactor trip. The valve cannot be partial-stroked for the same reason.

HCV-1387A These valves serve to isolate steam generator blowdown.

1387B They cannot be stroke-tested during operation quarterly 1388A because doing so would terminate steam generator blowdown 1388B and distrupt all volatile chemistry control. They cannot be partial-stroked because they are fully opened or fully closed.

HCV-1385 These valves serve to isolate main feedwater to the steam 1386 generators. Quarterly stroke-testing cannot be performed during operation because doing so would isolate feedwater to steam generators resulting in a reactor trip. These valves cannot be partial-stroked because they are either fully opened or fully closed.

HCV-2605A These valves serve as containment isolation valvqs to isol-2605B ate steam generator blowdown sampling lines. Stroke-testing 2607A cannot performed quarterly during operation because doing so 2607B would terminate blowdown sample line flow. The steam genera-tor blowdown activity monitor is on the sample line. Tech-nical Specification 2.9(1)d requires that blowdown activity shall be continuously monitored by the steam generator blowdown sample monitoring system. Partial-stroking cannot be performed since these valves are either fully opened or fully closed.

Category C Valves:

CH-198 This valve functions to prevent back-flow to the charging pump discharging pump discharge header. The valve is norm-ally open and there is no way that back-seating can be tested on reversal of flow due to system piping arrange-ments. Partial strok-testing cannot be performed for the same reason.

SI-159 According to the Commission's letter dated June 29, 1981: C 160 "The U.S. NRC has granted relief from certain requirements C of the ASME Code,Section XI, . . . The relief consists C of exemption from performing valve exercising at each C cold shutdown for check valves SI-159 & 160. In lieu C of this, the licensee has visually inspected SI-159 and C 160 . . (in 1980 & 1981)". C This relief expires September 26, 1983 C SI-139 These valves function to prevent back-flow to the safety 140 injection and refueling water tank. They will be part-stroked exercised every three months and full-stroke exercised at refueling outages. Full-stroke testing cannot be performed during cold shutdown or quarterly during opera-tion because doing so would require safety injection to the containment or reactor coolant system. A safety injection to the reactor coolant system during operation would cause uncontrolled boration and would introduce a thermal shock to the system. The recirculation line that are used for test-ing the LPSI and HPSI pumps for partial-stroking aren't large enough to fully open the check valves.

SI-102 These valves function to prevent back-flow to high pressure 108 and low pressure safety injection pumps and containment 111 spra- pumps. They cannot be testing during operation 121 quatterly or at cold shutdowns because doing so would 129 disrupt safeguard system alignment, and safety injection 135 into the containment or the reactor system would be required 143 for valve testing. Partial stroking cannot be performed for 149 the same reasons.

SI-100 These valves serve to prevent back-flow from high pressure 113 pressure headers to main safety injection headers. They cannot be fully tested during operation quarterly or during cold shutdowns since to do so would require a safety injec-tion to the reactor coolant system. Partial-stroking quarterly is possible since these pumps can be placed in a minimum recirculation mode of operation.

SI-207 These valves function to isolate reactor coolant pump leak-211 age flow from the safety injection tanks. These valves 215 cannot be stroke-tested during cold shutdowns or quarterly 219 during operation as to do so would cause drainage of the safety i injection tanks. Technical Specifications require safety injection tank levels to be maintained. The valves cannot be partial-stroked for the same reason.

SI-208 These valves function to prevent back-flow from the reactor 212 coolant system throgh the safety injection system. These 216 valves cannot be tested during cold shutdowns or quarterly 220 during operation because to do so would introduce cold charging water to the reactor coolant system causing thermal shock. The valves cannot be partial-stroked for the same reasons noted above.

SI-194 These valves function to prevent back-flow through the safety 195 injection pump discharge headers. These valves cannot be 196 stroke-tested during cold shutdowns or quarterly during oper-197 ation because to do so using the safety injection system 198 would require introducing cold water into the reactor coolant 199 system causing thermal shock and possibly a reactor excursion.

200 To do so using the chemical volume control system would dis-201 rupt charging and letdown flow to the reactor coolant system 202 causing chemical and volume control to the system to be dis-203 rupted.

204 205 SI-175 These valves serve to prevent back-flow from the contain-176 ment spray headers. These valves cannot be tested to the open position since to do so could c.2se spray in contain-ment. No stroking the valves poses no safety impact for the following reasons:

1. Adequate heat removal from containment can be achived during a DBA by use of only one containment spray header with three containment spray pumps. Hence, only one of the check valves is required to open.

2. The containment air filtration and cooling system is fully redundant to the containment spray system.

3. The containment air filtration and cooling system con-tains redundant components. During a DBA, sufficient iodine removal is achieved with 50% of the system operating and sufficient pressure reduction accom-plished with any three air coolers operating.
