1 INTRODUCTION The Donald C. Cook Nuclear Plant, owned by Indiana Michigan Power Company is located five miles north of Bridgman, Michigan and consists of two nuclear power units.

Each unit employs a pressurized water reactor nuclear steam supply system furnished by Westinghouse Electric Corporation.

The Unit 1 reactor is currently designed for a power output of 3250 MWt and the Unit 2 reactor is designed for a power output of 3411 MWt, which are their licensed ratings.

The approximate gross and net electrical outputs of Unit 1 are 1056 MWe and 1020 MWe and of Unit 2 are 1100 MWe and 1060 MWe, respectively.

The main condenser cooling method is open cycle using Lake Michigan water as the cooling source.

The Cook Nuclear Plant was the first domestic nuclear facility to employe the ice condenser reactor containment system.

The American Electric Power Service Corporation was the architect-engineer and constructor.

n 1.16 REPORT - WORK FUNCTION CATEGORIES Reactor Operations and Surveillance Those activities involved with operating the plant or monitoring it's operation, including chemistry, performance testing, surveillance testing, etc.

The plant may be at any power level, including zero, and still have work falling into this area.

Many STP's run during shutdown or refueling may still 'all into this category.

Routine Maintenance All equipment or system maintenance, whether preventative or restorative, which does not involve significant modifications to equipment or systems.

Included is I&C repair work, as well as work to adjust operable equipment to improve performance (adjusting fan blade pitch, for example).

Inservice Inspection

\\

Inspections of equipment and systems to monitor changes that would be detrimental to function or integrity.

Also included is all work required to permit such inspections, such as building required scaffolding, removing or replacing supports of insulation, or disassembly of valves, pumps, etc.

Not included are inspection to

. assess or monitor normal wear, etc.

For example, dissembly of a charging pump to inspect bearing wear would not be Inservice Inspection, but dissembly to inspect for rotor cracking or casing damage would be.

Inspection of a weld on a newly added line is Special Maintenance, or inspection of a weld repair at a leaking fitting is Routine Maintenance.

Special Maintenance All work on equipment or systems performed to make significant modifications.

Installation of new systems or equipment, replacement or addition of supports or hangers, addition of new lines or instruments, removal of existing equipment, replacement of existing equipment with signi"icantly different equipment are all Special Maintenance.

For example, replacement of a properly functioning, original equipment pressure transmitter with a different model with improved characteristics or certification would be Special Maintenance, but replacement or a malfunctioning O

pressure transmitter with a newer or improved model would probably be Routine Maintenance.

3 O

Waste Processing All work associated with decontamination of equipment, areas, systems, etc. (if not an integral part of another job, such as pump repair), collection and processing of waste, whether solid, liquid, or gas.

Operations in support of waste handling are also included.

For example, draining a filter to permit changing it, or venting it after changing are part of Waste Processing, but valving a clean filter into the system is Reactor Operations.

Repair of the Baler or drumming room crane is Routine Maintenance.

Refueling l

All work is directly concerned with refueling the reactor, including all support operations, is classified as Refueling.

Testing the polar crane or installing the cavity filter rig is part of Refueling, as is cavity decon before or after flood-up.

Changing the cavity filter, however, is Waste Processing and fixing the manipulator crane is Routine Maintenance.

20 STEAM GENERATOR TUBE INSEF

.CE INSPECTION REPORT UNIT 2 March 1987 On March'3, 1987 the unit ~was shutdown due to a primary to secondary leak rate of.247 GPM.

The eddy current program was eventually escalated-to test 100% of the tubes in all four steam generators.

In steam generator 21, 5 tubes were tested full length, 8 through the U-Bend and 3,233 through the seventh support plate on the hot leg side.

Seventeen tubes were removed from service by mechanical-plugging.

In steam generator 22, 225 tubes were tested full length, 62 through the U-Bend and 2,890 through the seventh support plate on the hot leg side.

Thirty three tubes were removed from service by mechanical plugging.

In steam generator 23, 5 tubes were tested full length, 87 through the U-bend, and 3,085 through.the seventh support plate on the hot leg side.

A total of 38 tubes were removed from service by mechanical plugging.

In steam generator 24, 212 tubes were tested full length, 16 through the U-bend and 2,959 through the seventh support on the hot leg side.

Twenty-one tubes were removed from service by mechanical plugging.

Attached are summary reports of indications found, their location, and whether or not the tube was plugged.

43 STEAM GENERATOR TUBE INSERVICE INSPECTION REPORT-UNIT 2 September 1987 On August 26, 1987 the decision was made to bring Unit 2 down to repair the reactor coolant pump hatches.

On September 1,.1987 the decision was made to perform 100% eddy current inspection of tall four steam generators.

This inspection was scheduled for October, but was moved up one month due to the unit being down anyway.

All tubes were tested from the tube end hot leg to the seventh support plate hot leg.

On steam generator 21, 3,229 tubes were tested.

Fourteen tubes were removed from service by mechanical plugging.

On steam generator 22, 3,144 tubes were tested.

Seventeen tubes were removed from service by mechanical plugging.

On steam generator 23, 3,140 tubes were tested.

Seventeen tubes were removed from service by mechanical plugging.

On steam generator 24, 3,166 tubes were tested.

Thirty tubes were removed-from service by mechanical plugging.

Attached are summary reports of indications found, their location and whether or not the tube was plugged.

70 CHANGES TO FACILITY Brief descriptions and summary safety evaluations for design changes (RFCs) made to the facility as described in the Donald C. Cook Nuclear Plant Final Safety: Analysis Report (FSAR) are presented in this section. These changes were completed pursuant to the provisions of Title 10, Code of Federal Regulations subsection 50.59'(a).

RFC-12-1729 Brief Description RFC-DC-12-1729 installed an overvoltage alarm relay on the Plant battery buses 1-AB, 1-CD, 2-AB & 2-CD.

The alarm relay will be activated at voltages exceeding 280 VDC.

The change was initiated because of the failure of two 120-volt A.C.

vital buses during a battery equalizing charge of the CD batteries.

This failure, caused by battery charger voltage being in excess of the DC input limit, resulted in a reactor trip and safety injection. The installation of the alarms will alert the operator should an overvoltage condition occur.

Safety Evaluation The subject RFC has been classified as safety-interface. NS&L reviewed this design change with no unresolved open items and concluded that this RFC does not constitute an unreviewed safety question as defined in 10 CFR 50.59, nor does it create a substantial hazard to the health and safety of the public.

RFC-DC-12-1797 (Shared System)

Brief Description RFC-12-1797 provides for the installation of a 2" diameter tie line between the CVCS holdup tanks and the gas decay tank vent header. This new tic line will permit purging nitrogen into one CVCS tank venting this y

tank to the Aux. Bldg. exhaust system via the gas decay tank normal release line while maintaining a normal vent lineup (to the suction of the waste gas compressors) on the remaining holdup tanks. Four tie-ins to existing systems were required and consist of one in each CVCS HUT room between the cancs and vent isolation valves CS-152, 153, 154 and between RRV-305 and WD-297.

c-71 CHANGES T0' FACILITY (CONT.)

Safety Evaluation This RFC has been classified as safety interface because it involves modifications to the Hold Up Tanks which is a Seismic Class II System.

.The new tie line being installed is Seismic Class II piping up to and including the first isolation valve. The rest of the tie line is classified as Seismic Class III.

Nuclear Safety and Licensing has reviewed the proposed change as per the review criteria in NS&L Procedure No.7.

As a result of the review, to the extent available information permits, the following items have been identified for review.

Item 1.

The Seismic Analysis and installation of the tie line must be performed as per the alternate analysis criterion.

Item 2.

Upon completion of the installation of the subject tie line/ valves a leak tight testing must be performed to assure uncontrolled release of the waste gases will not occur.

The purpose of this review is for procurement, design and installation.

With this in mind, it is concluded that this RFC doss not constitute and unreviewed safety questions as defined in 10 CFR 50.59, nor does it create a substantial hazard to the health and safety of the public.

RFC-12-2912 (Unit 1 Only)

Brief Description RFC-DC-12-2912 removed the AFW automatic pump trip on low suction pressure.

The trip function was replaced by operator / alarm action. The low suction pressure trip system, which consisted of three pressure switches (per pump), one gage protector, 2 out of 3 logic and a 5.5 second time delay relay, was replaced with one pressure switch (alarm function only),

which does not require a gage protector and is equiped with a 10 second time delay relay.

The time delay has been increased due to an inherent pressure oscillation in the AFW suction line which occurs during pump start-up.

Safety Evaluation RFC-DC-12-2912 is classified "safety-interface" because the pressure switch activates an alarm and alerts the operators of a potential problem with a safety related system (AFW).

The Nuclear Safety and Licensing Section (NS6L) reviewed R7C-DC-12-2912 under the provisions of NS&L Section Procedure No. 7, "Saf*ty Review of Design Changes".

L_

72 CHANGES'TO FACILITY (CONT.)

The results of this review were that no open items exist with regard to RFC-DC-12-2912.

Based on NS&L's review it is concluded that RFC-DC-12-2912 does not constitute an unreviewed safety question as defined in 10 CFR 50.59, nor does it create a substantial hazard to the health and safety of the public..

CHANGES TO PROCEDURES Brief descriptions and summary safety evaluations for changes made to procedures as described in the Donald C. Cook Nuclear Plhpt Final Safety Analysis Report are presented in this section.

Emergency Operating Procedures The Unit 1 and Unit 2 Emergency Operating Procedures (49 procedures on each unit) were revised to incorporate the Westinghouse Owners Group Emergency Response Guidelines and were issued pursuant to NUREG 0737, Item I.C.I.,

"Guidance for the evaluation and development of procedures for transients and accidents".

Emergency Operating Procedures for Unit 1 were issued on March 31, 1986, and for Unit 2 in June of 1986.

The safety evaluation concluded that the procedure revisions did not constitute an unreviewed safety question as defined in 10 CFR 50.59.

10 CFR Part 50, Appendix R, III.L Procedures safe shutdown procedures and plant modification / repair procedures were issued to implement the requirements of 10 CFR 50, Appendix R,

Section III.L, "Alternative and dedicated shutdown capability".

The procedures were issued in June, 1986.

The safety evaluations of these procedures determined that they did not constitute an unreviewed safety question as defined in 10 CFR 50.59 although the draft procedure was modified as the result of the 50.59 review process.

Loss of D.C.

Power Procedures Emergency operating procedures were issued for Units 1 and 2 (two per unit) to implement recommendation #7 of INPO SOER 83-5, "DC Power System Failures", and recommendation #2.C of INPO SOER 81-15 "Partial Loss of D.C. Power".

The safety evaluations of these procedures determined that they did not constitute an unreviewed safety question as defined in 10 CFR 50.59.

74 Unit 1 Main Steam Safety Valve Set Point Verification Procedure The change in main steam safety valve set point verification consisted of a new procedure, 1 MHP SP.126, which allowed setpoint testing of main steam safety valves in modes 1 through 3.

One safety valve is tested at a time.

During testing the valve is considered inoperable per T/S 3.7.1.1.

Thus per the action statement, the Power Range Neutron Flux High Setpoint is reduced per Table 3.7-1.

The most likely problem with the test would be the safety valve sticking open.

Since only one valve at a time would :ie tested, any transient resulting from a stuck-open valve is bounded by the Unit 1 steam line break analysis, found in Appendix 146 to the Updated FSAR.

This conclusion is valid in modes 1, 2, and 3.

Accident analysis assumptions which rely on the safety valve to open to relieve pressure, are maintained by adherence to T/S 3.7.1.1.

As the test has some potential for causing a stuck-open safety valve during power operation, there is a possibility of a reactor trip.

Although this potential exists, its possibility is minimized by providing a hydraulic closing device.

Even if a trip occurs the consequences are bounded by the existing accident analyses.

A change to Section 10.2.4 of the Updated FSAR was requested as this section states that safety valves are tested "during scheduled outages".

f-NS&L concluded that testing of the main steam safety valves in Modes 1, 2, or 3 does not constitute an unreviewed safety question as defined in 10 CFR 50.59.

75 TEST AND EXPERIMENTS One test not described in the FSAR was performed on Unit 1 that had _ the potential of operating the plant outside of the bounds of the initial conditions and assumptions used in the FSAR or in a manner not described in the FSAR and/or which could have an adverse effect on reactor safety.

• • 1 THP SP.141, Unit 1 Turbine Volumetric Flow Test, was performed in May 1987 to obtain data to support the T-Hot reduction program planned for Unit 1.

The objective of the test was to determine the minimum main steam pressure and the equivalent Tavg possible for full power operation on Unit 1.

Westinghouse Electric Corporation performed the safety evaluation to address the validity of the current Unit 1 licensing basis during the proposed test.

The evaluation justified a Reactor Coolant System (RCS) temperature reduction of 20 F for a duration of 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />.

The evaluation encompassed the following items:

1)

Test affect on Primary Components - Reactor Vessel and Steam Generator.

2)

Test effects on Non-Loss of Coolant (LOCA) Analysis

"'a--ture from Nuclear Boiling (DNB); Non-DNB

.erations, Boron Dilution, Loss of Load, Loss of Normal ter/ Station Blackout, Rupture of Main Feedwater Line,

... trolled Rod Cluster Control Assembly (RCCA) Withdrawal at Power, Locked Rotor and Hot Full Power (HFP) Rod Ejection and Steamline Break Mass and Energy Release.

3)

Large Break LOCA Evaluation.

4)

Containment Evaluation - Long term and Short term.

5)

Small Break LOCA Evaluation.

6)

LOCA Forces.

7)

Steam Generator Tube Rupture (SGTR) Evaluation.

The analysis concluded that the test did not involve any unreviewed safety question as defined in 10 CFR 50.59.

76 CHALLENGES TO PRESSURIZER POWER OFERATED RELIEF VALVES AND SAFETY VALVES There were no challenges to the pressurizer power operated relief valves (PORVs) or the safety valves resulting from an actual overpressure condition.

One event occurred on Unit 2 on March 4, 1987, that caused an actuation of pressurizer PORV, NRV-152.

The actuation occurred in the cold overpressure protection mode with the RCS in Mode 5, Cold Shutdown.

During cold shutdown operation, loop 1 hot leg wide range RCS pressure actuates pressurizer PORV, NRV-152 and loop 2 hot leg wide range RCS pressure actuates pressurizer PORV, NRV-153.

The setpoint for both valves is 420 psig i 15 psig.

The operators were manually controlling RCS pressure based on loop 2 hot leg wide range pressure indication.

This indication was at approximately 385 psig when NRV-152 was actuated.

Checks of the loop 1 and 2 hot leg wide range RCS pressure instrumencs determined that both were within allowable tolerances.

It is therefore concluded that this event occurred as a result of instrument tolerance stack-up which resulted in the actuation at an indicated pressure of 385 psig on the pressure channel being monitored.

The event was reported pursuant to the requirements of Technical Specification 3.4.9.3, Action (c) via a Special Report dated April 3, 1987.

77 Results of Irradiated Fuel Inspections During 1987, two separate examinations were performed on the fuel assemblies discharged from Unit 1 Cycle 9.

These examinations were conducted in parallel with or just after the core was unloaded, and the intent was to determine fuel pin failure as well as gross structural defects in the assemblies.

The first examination was a routine binocular inspection of the fuel assemblies

(* *12 THP 6040 PER.353).

As each assembly is brought into the Spent Fuel Pool, it is examined on all four sides visually.

The examiner is looking specifically for torn or missing grid straps, missing or damaged fuel pins, excessive clad hydriding, or rod bow to gap closure.

This inspection is primarily intended to detect fuel damage caused by mechanical interaction between assemblies or baffle jetting, and is done during each refueling.

There was no visual indication of any fuel damage found.

Due to Iodine and Cesium levels in the RCS high enough to indicate leaking fuel assemblies, AEPSC issued a contract to Advanced Nuclear Fuels (ANF) to provide an Ultrasonic (UT) inspection of all assemblies from the Cycle 9 core.

The Ultrasonic System works by a probe transceiver sending a high frequency sound wave into a fuel pin and measuring the strength of the returning signal or "ring back".

By monitoring the strength of this ring back a determination can be made as to whether or not the fuel pin contains water.

In this way, not only can an assembly be determined to be leaking, but the individual failed pin can be located for a potential replacement effort to make the assembly usable.

The Ultrasonic Testing sequence is as follows:

1.

The assembly is placed in the can with a given orientation.

2.

The probes are inserted between each of the rows of fuel pins following the XY Table's indexing.

3.

When the last row is scanned, the assembly is rotated 90' and the process repeated once more.

4.

The data is reviewed, and any questionable areas are re-scanned and/or the other two assembly faces are tested (scanning two sides is one complete test).

5.

The assembly is removed, and another is brought in.
