) .
Failure analysis of the pipe break will be performed by FPI, International, with the metallurgical analysis performed by Altran Laboratories. The results of this failure analysis will be used to help identify other high risk pipe locations that need to be inspected before restart and will also be used as input to the RCA and to the overall j erosion / corrosion program assessment. This effort is discussed in a separate report.
l Assessment of Erosion / Corrosion program will be perfonned by the assessment team l headed by J. L. Skiles. This activity will help ensure plant piping systems are being l maintained consistent with safe and reliable operation. This effon is also discussed in a -
separate repon.
All other damage assessments will be led by System Engineering teams. Walkdowns will ensure necessary repairs and testing are identified and supponing analyses per-formed where reqmred. MWRs will be prepared and work scheduled for completion.
This effon is the subject of this report.
l - 2. Srant The scope of the Damage Assessment is defined as follows: ;
A. Experienced individuals (i.e., System Engineer, Design Engineer, and/or Maintenance l
Planner or Craft) will be assigned to teams to investigate systems and report damage in
" Damage Assessment Reports." Central to this investigation is a walkdown of equipment in the break affected zone.
B. Every plant system that could be potentially affected by the break will be considered.
C. The break affected zone will be the primary area for walkdowns.
D. System interactions outside the break affected zone will be considered (e.g., electrical bus gmunds, instrument air, etc.).
E. The following parameters will, at a minimum, be considered by the Damage i
Assessment Teams:
The effects of the physical movement of equipment and supponing mechanisms caused by the steam release.
, The effects of steam impingement on equipment. I The effects of wetting of equipment due to steam condensation.
a l

l l-
. The long term effects of the event on equipment.
. The effects of the insulation and dust distributed throughout the break affected zone by the event:
l To assist the damage assessment teams in planning 'and executing the walkdowns, a matrix entitled " Anomaly Resolution Guideline" has been ymiced. System Engineers
- , will utilize the functional requirements from this matrix in scoping and performing the
! walkdowns for each system to ensure critical break effects are. considered. This guide-line is attached to this report.
l .
l l F. Teams will be assigned equipment for walkdowns based on the System Engineers l L
assigned systems.
l l
( G. The break affected zone is defined as the Turbine Building. The area in the blowdown l zone is considered the primary area for walkdowns. The basis for this is discussed in i the following section. l H. The System Engmeer representative on each walkdown team will ensare appropriate Maintenance Work Documents are prepared.
I. It is intended that the initial damage assessment be completed as soon as possible to i
, allow the scheduling and planning process as much time as possible to prepare work l packages for execution. However, it is also intended that the damage assessment be l dynamic to ensure all issues are identified to assure safe operation and high reliability l of the station following restart. Therefore, follow-up walkdowns and analyses may be required. .
l J. It is intended that the Syr, tem Engineer representstive provide input to assure the proper l prioritization of work activities within the resources allocated.
K. Above all, it is imperative that the System / Design Engineer ensure that his/her l walkdowns will assure the continued safe and reliable operation of Fort Calhoun .
l Station. The very nature of this damage assessment will rely heavily on the experience
! of the Engineering and Maintenance / Planning staff.

A. Definition of the break affected zone. .
After a pieliminary walkdown and discussions with personnel that were on site during l the event, the Turbine Building was the only area selected es needing damage assessment. The reasoning in selecting only the Turbine Building and components l located in the Turbine Building for damage assessment includes the following:
l
- l. 1. There was no evidence of any steam intmsion into any of the following buildings:
l
- Service Building
- Maintenance Shop
- Auxiliary Building This was confirmed by interviews with personnel on site during the event and the lack of any fire detection alarms for these buildings, with the exception of two fire detector alarms in Corridor 53 and two detector alarms in the Water Plant, before, during, or after the event. All four fue detector alarms would be expected after reviewing their locations and the steam plume. All of the buildings in question, Service Building, Maintenance Shop, Auxiliary Building, and Turbine Building have separate, non-communicating HVAC systems, with the exception of a grille between the Water Plant and the east wall of the Turbine Building and a fire barrier between the cable spread room and the west wall of the Turbine Building.
Additionally, all the buildings are in different fire areas, which means that there l
are fire barriers between the buildings. The fire barriers are not designed as steam I barriers; however, as evidenced by the lack of fire detection alarms, they are l effective as a low pressure steam barrier. ..
l i
- 2. There was no evidence of dust or insulation particle migration from the Turbme :
Building into the Service Building. There was some very light dusting in the Service Building of what apM to be ceiling tile dust that is judged to have '
been deposited on desk and table tops from the turbine trip. This is not an uncommon phenomenon following a turbine trip from full power.
- 3. There was no evidence of dust or insulation particles in the Maintenance Shop after the event with the exception of a small area in the south east comer of the shop. There was a light dusting of dust or very fine insulation particles that could have been dislodged during the turbine trip.
- 4. There was no evidence of dust or insulation particles in the Auxiliary Building.
I S. A qualitative evaluation of the blowdown from the high energy line bicak reveals that the blowdown lasted for less than 20 seconds. 'Ibe zone from the blowdown extended from the pipe outward to iapact on the motor control center (MCC 4CS) 3
_ _ _ m.. - _ . _ _ _ _ _ - _ _ _ _ _ _ . . _ . _ . _ _ . _ . . _ . _ _ _ . . _ _ . . _
! and then the Maintenance Building wall with a diameter about 20-30 feet. In this .
! zone, the temperature of the two phase b:owdown could range from operating temperature of about 400*F to some lower temperature above 212*F. Outside .
I thisjet impingement zone, the steam would rapidly cool and depressurize, so that the areas in the Turbine Building around thejet impingement zone would likely be at or below 212* F with virtually no pressurization until the blowdown terminated, at which time any steam would rapidly cool and condense.
Consequently, the observations above regarding no visible effects in the Service, Maintenance or Auxiliary buildings are valid, and it is reasonable to conclude that the break affected zone should be limited to the Turbine. Building and, in 1 particular, the areas near the break. Other areas in the Turbine Building are most i likely subject to the effects of a wet environment and should also be walked down with this in mind.
l B. The following are the Fort Calhoun Station Systems and the basis for their inclusion in the recovery. effort or why the system was not specifically included in the recovery effort: ,
l i
e Architectural (AE) - The Turbine Building is covered in the scope of the l l i
inspection. Before power operation of the station, Procedure SE-PM-SE-1003,
" Turbine Building Structure Inspection," will be performed. Any anomalies l noted will either be repaired or evaluated for start-up.
- Auxiliary Feed Water (AFW) - The portion of the AFW system located in the Turbine Building (FW-54 and associated support equipment) is included in the scope of the recovery effort. A walkdown was performed by Merl Core (Manager - S.E.) and no problems were noted. FW-54 functioned satisfwtorily for several days after the event with no problems noted. ..
e Auxiliary Steam (AS)- The AS system was walked down by Carmen Ovici l
(S.E.). No damage to the system piping was noted; however, a maintenance work document was generated to inspect and clean the affected auxiliary steam heater.
l e Auxiliary Monitoring Systems (including Seismic Monitoring, Loose Parts l Monitor, Intemal Vibration Monitoring, Toxic Gas, Contamment Hydrogen, Meteorological Monitoring, 800 Mz Radios, Station Grounding, and Catix>dic Protection Systems) are not included in the scope of the recovery effort since they are not located in the Turbine Building.
e Auxiliary Monitoring Systems (including Plant Communication Systems and Plant Alarms) are not included in the scope of the recovery since they are included in the PRC Start up list.

in the scope of the recovery effort. A walkdown was performed by Mark Nay (S.E.) and no problems were noted. The majority of the CF equipment is located' in a, Kelly enclosure on the opposite end of the Turbine Building.
- Chemical and Volume Control (CH) - The CH system is not included in the scope of the recovery effort since none of the components of this system are located in the Turbine Building.
l e Circulating Water (CW)- The CW system is included in the scope of the recovery
! effort. The Turbine Building portion of the CW system was walked down by l Carmen Ovici(S.E.). No abnormalities were noted.
! e Compressed Air (CA) - The CA system is not included in the scope of the recovery effort since the source of air for the CA system is in Room 19 of the l Auxiliary Building. As discussed above, it is not reasonable to believe that a steam environment existed in any portion of the Auxiliary Building; therefore, there is no reason to believe that moisture entered the CA system. Note: The Turbine Building portion of the CA system was visually inspected, during tours, for physical damage.
l e Component Cooling Water (CCW) - The CCW system is not included in the j scope of the recovery effort since none of the components of this system are l located in the Turbine Building.
e Control Element Drive Mechanisms (CEDM) - The CEDM system (including l position indication system, clutch power supply, and rod drop test panel) is not l included in the scope of the recovery effort since none of the components of this -
system are located in the Turbine Building.
o Demineralized Water (DW) - The DW system is included in the scope of the
! recovery effort. The Turbine Building portion of the system was walked down by l Carmen Ovici (S.E.). No abnormalities were noted.
l e Electrical (EE) - The EE system components located in the Turbine Building are l included in the scope of the recovery effort.
The Turbine Room Motor Control Centers (MCC) were walked down by Steve Miller (S.E.) and Meri Core (Manager - S.E.). The damage assessment report generated from that walk-down is attached.
I Cable Systems were walked down by John Tucker (S.E.) and Jim Foley (S.E.).
The damage assessment report generated from that walk-down is attached.

The damage assessment to the MCCs and to cabling in the break affected zone -
entails review and analysis for the extent of the inspections prior to walkdown and l
MWR preparation. Detailed inspection plans were yweized for this assessment '
and are attached.
l .
- Emergency Diesel Generator (DG) - The DG system is not included in the scope of the recovery effort since none of the components of this system are located in the Turbine Building.
l e Engineered Safeguards Features (ESF) - The ESF system is not included in the i
! scope of the recovery effort since none of the components of this system are i located in the Turbine Building.
- Feedwater (FW) - The FW system (including the condensate system), located in the Turbine Building is included in the scope of the recovery effort and was walked down by Craig Fritts (S.E.) and Ben Bickels (S.F.M.). The damage !
j assessment report generated from that walk-down is attached. '
l e Fire Protection (FP) - The FP system, located in the Turbine Building is included in the scope of the recovery effort and was walked down by Chris Sterba (S.E.)
and Mark Stanley (Planner). The damage assessment report generated from that walkdown is attached. Note: The Turbino Building Fire Protection System is also included on the PRC Startup List as item #6.
- Fuel / Lube Oil (FO, LO) - The FO system is not included in the scope of the recovery effort, with the exception of that portion of the system that supplies the diesel driven AFW pump, since the rest of the system is not located in the Turbine
, Building. The portion of the FO system that feeds FW-54 was walked down by -
1 Merl Core (Manager - S.E.) with no abnormalities noted. FW-54 functioned satisfactorily for several days after the event with no problems noted. The LO system is included in the scope of the recovery effort and was walked down by Kevin Naser (S.E.) and Jerry Mixan (Planner). The damage assessment report generated from that walk-down is attached.
e Fuel Handling and Spent Fuel Pool (FH & SFP) - The FH and SFP systems are not included in the recovery effort since none of these systems are located in the Turbine Building.
l e Gas Piping (HG/CO2 )- The HG/CO 2system is included in the scope of the recovery effort and was walked down by Mark Nay (S.E.). No problems were noted. The gas systems are closed systems and are not open to the Turbine Building atmosphere. The systems also functioned for several hours after the
! event with no problems noted.

e Heating, Ventilating, and Air Conditioning (HVAC) - The HVAC system is -
included in the scope of the recovery effon; however, since the design of the l' Turbine Building HVAC is such that there are only supply fans and roof fr.ns, and no " internal" air-handling systems, the scope will be limited to the long term
- effects on the roof fans froin an economic stand point only. This ponion of the
- inspection effon will not be performed until after re-start and all clean-up efforts are complete.
I e Instrument Air (IA) - The IA system is not included in the scope of the recovery effort since the source of air for the IA system is in Room 19 of the Auxiliary i Budding. As discussed above, it is not reasonable to believe that a steam environment existed in any portion of the Auxiliary Building; therefore, there is no reason to believe that moisture entered the IA system. Note: The Turbine
- Building portion of the IA system (including instrument lines and actuators) was j visually inspected, dunng tours, for physical damage. j i
e Main Steam (MS) - The Turbine Building portion of the MS system is included in j
!' the scope of the recovery effort and was walked down by Craig Fritts (S.E.) and i l Ben Bickels (S.F.M.). The damage assessment report generated from that walk-i down is attached.
e Plant Computer System (PC) - The PC system (including ERF computer, QSPDS l
i and SMM) is not included in the scope of the recovery effort since the computer systems are not located in the Turbine Building.
j e Plant Security System (PS) - The PS system is not included in the scope of the recovery effort since the system is electronically monitored and was checked by i
the guard force for operability. Additionally, because of the closed loop -
- monitoring system incorporated into the system, any anomaly would be detected by the SAS or CAS monitoring officer.
- Potable Water (PW) - The PW system was included in the scope of the recovery effort and was walked down by Carmen Ovici (S.E.). No damage was noted.
e Radiation Monitoring (RM) - The Turbine Building portion of the RM system (RM-057 and RM-064) is included in the scope of the recovery effort. A walkdown was performed by Don Flegle (S.E.) with no problems noted.
e Raw Water (RW) - The RW discharge header and the raw water backup discharge header, located under the mezzanine level of the Turbine Building, on the north side, are included in the scope of the recovery effort. Both headers were inspected for damage by Tom Dailey, (S.E.). Both headers appeared to be in good condition with no damage being noted either to the pipe or associated pipe supports .

4 e Reactor Coolant (RC) - The RC system (including the reactor, steam generators, -
and associated equipment) is not included in the scope of the recovery effort since none of the components of this system are located in the Turbine Building. -
e Reactor Protection System (RPS) - The RPS system (including NI, DSS, and Neutron Flux Monitor) is not included in the scope of the recovery effort with the exception of turbine stop valve limit switches which supply a turbine trip signal to the RPS and are located in the Turbine Building. A walkdown was performed by
)
' John Tucker (S.E.) and Maintenance Work Order 971409 was written to inspect the switches.
Safety Injection (SI) - The SI system is not included in the scope of the recovery .
effort since none of the components of this system are located in the Turbine Building.
- Sampling (SL) - Portions of the SL system are included in the scope of the recovery effort and were walked down by Chris Sterba (S.E.). The secondary sampling panel is located in the Turbine Building, but did not sustain any damage due to the steam leak. The system has been in operation since the event and no problems have been reported.
e Main Turbine (ST) - The ST system (including EHC, control valves, stop valves, and turbine axillaries) is included in the scope of the recovery effort and was walked down by Kevin Naser (S.E.) and Jerry Mixan (Planner). The damage assessment report generated from that walk-down is attached. The Generator, Alterrex, and Stator Cooling Systems were walked down by Rich Ronning (S.E.),
Tom Kazor (Electrician), and Cal Huey (General Electric Technical Representative). The damage assessment report generated from that walkdown is -
attached.
e Waste Disposal (WD) - The WD system (Radwaste Systems) is not included in the scope of the recovery effort since none of the components of this s'ystem are located in the Turbine Building.
e Turbine Plant Cooling Water (TPCW) - The TPCW system was included in the scope of the recovery effort and was walked down by Carmen Ovici (S.E.). No ;

l 4. Summary of Dammoe Aa, ament and Recovery Actintigg .
To date, with the exception of the extraction steam piping, and motor control centers located in the bretk affected zone, there have been no major anomalies noted in the Turbine Building. There have been severaljunction boxes noted that had slight amounts of moisture inside that was easily cleaned up by blowing them down with compressed air. Additionally, there have been no cables tested that were unsatisfactory. There has been no structural damage to the Turbine Building itself, and no indications of steam or dust particle entry into any other building in the power block except for the Turbine Building.
I t
During the event, and the subsequent plant cool-down, all equipment performed as expected, even during the time of elevated humidity, even that equipment in the break affected zone.
Much of the equipment operated for several days following the event and equipment has l been retumed to operation following walk-downs and in preparation for re-start of the i station. All equipment in this category has operated satisfactorily. As a precautionary measure, to assure reliability of the station following start-up, several preventative l maintenance measures were undertaken. These measures include, but are not limited to, the following:
e Replacement of turbine servo valves e Calibration checks of selected instruments in the Turbine Building e Checks of the Gai-Tronics system and associated emergency alarms j s Checks of the Station Blackout emergency lighting as well as station battery emergency lighting e Preventative maintenance of MCC breakers that could have been affected e Detailed cleaning and inspections of all MCCs at the north end of the Turbine Building e General clean-up of the entire Turbine Building e Numerous building tours by management, system engineers, operations staff, and craft -
persons of all systems located in the Turbine Building, or systems that could have been affected by the break affected zone Note: These activities are either in-progress and will be complete prior to return to power or are complete at this time.
In summary, detailed walk-downs and inspections have been underway in the entire Turbine Building and especially intensive in the break affected zone since April 22,1997. Other than " expected" damage to the motor control center, MCC-4CS, the damage to the extraction steam lines, and damage caused by high energy steam impingement, there have i been no other components discovered, to date, that have failed due to the event.

. Personnel: J. Tucker J. Foley FunctionalAhea: Cable Assessment Observations: Inspected cables and cable trays in the damaged area around Control Valve No. 1, Stop Valve No. 1, and MCC-4C5. There are two cables hanging from open conduits. These cables are believed to be for plant lighting.
Cable Tray south of Control valves: This tray appears to primarily carry the cables for the-Control valves. The 12 inch tray consists of 2
, tiers. The east and of this tray was extensively l damaged, particularly the lower tray section. The l l last few feet of the lower tray were empty, i hawever the damage did affect the connecting conduits and cables for the 2 eastern most control Valves. The unistrut cable tray support has been j significantly damaged.
Cable Tray below Stop Valves: This tray appears to carry cables for the Stop Valves. This tray is also 2 tiers. No tray damage was noted. The cables leaving this tray in sealtight to the east most Stop Valve may have been subjected to the steam blast and stressed. .
Cable Tray' north of HCC-4C5: one of the unistrut support hangers unnediately east of T6 for this cable tray is twisted. This support has an emergency horn and light mounted to it. The light support bracket appears stressed. Several tray covers west of T6 are displaced and it looks like a tray section divider is sticking out of the third tier from the top. Two pieces of lumber (2X4) can be observed in the fourth tier from the bottom. These could have been present prior to the steam line rupture.
Conduit to MOV RCV-978 has been bent.

Personnel: R. Ronning T. Kazor C. Huey (GE) l Functional A'rea: Generator /Alterrex/ Stator Cooling observations:
There is no visible damage to the main generator or the Alterrex housing on the turbine deck. The only;need is to clean the exterior of the generator and the Alterrex housing. The voltage regulator panels suffered no damage. The stator cooling pump skid and associated piping and equipment is also undamaged.
The piping and equipment associated with the hydrogen system is also undamaged. The stator cooling panel AI-134 is undamaged with the only anomaly being that flow meter (FIA-1288) which measures stator cooling flow is flashing. I&C was contacted and it is believed that this flashing could be a problem in the loop.
No other generator problems were observed.

. Personnel: T. Dailey S. Bottum l Functional Area: Equipment Supports Observations: Pipe supports and equipment supports in the general area of the pipe rupture were inspected for evidence of damage and to assess the need for repairs. Only three damage supports were noted on the inspection; all three being on the 4th stage extraction steam line that ruptured.
The first damaged support is MSH-61 which is a spring can hanger immediate).y upstream of the pipe rupture. The upper rigid 'aanger rod is bent due to the pipe movement afte. the failure. The second damaged support l'> the rod hanger just downstream of the pipe ;:upture. The damage to the rod hanger is minor r.d almost appears to have existed prior to tFs event. The third damaged pipe support is a rigid horizontal restraint weld to column TC-7X. The damage to the support is considered moderate and must be repaired.
The only other abnormality noted was on the steam dump header that leads into the condenser. The insulation on the pipe appears to have evidence of a thru wall leak or a flange leak. The insulation I was discolored but not wet at the time of the .
inspection. This deficiency is not related to the pipe rupture.

MCC-4C5 .
RECOVERY PLAN Damage Assessment
- Back panels were opened and deformed by the steam jet impingement.
- Debris was blown into the back of the MCC. Cables inside the MCC and MCC interior panels are coated with debris. Full extent of debris intrusion is unknown, but assumed to be limited to the back side of the MCC.
- Field report was that the MCC is leaning forward (away from the steam leak source), indicating possible structural damage to the MCC.
- The MCC is still energized, providing power to selected loads. One phase of the 3-phase 480-volt feed is grounded (i.e., 0 volts to ground on one leg). Ground has been cleared.
Required Repairs
- 1. General cleanup of MCC interior and cables, then additional damage assessment to determine best course of action.
- Inspect each cable in the exposed portion of the MCC for insulation damage.
- Inspect each MCC cubicle (MCC-4C5) for damage and debris.
- 2. Determine and eliminate source of ground on power feed. (Complete)
- 3. Replace / repair any damaged cables. -
Recovery Options
- 1. Salvage MCC for return to service
- Reform or replace back panels on MCC. Replacement panels can either be procured or taken from spare sections of MCC-3C4C-2.
i
- Replace MCC cabling as necessary.
- Stabilize MCC structure (may require input from DEN-Mechanical).
l
~
- 2. If damage is too severe, replace MCC-4C5 (see Options 2a and 2b below) .
I
- a. Procure new MCC (DEN-Electrical assistance required to evaluate.
replacement MCC) l An' entire MCC would be procured under this option. Depending on the compatibility of the new MCC with the existing cubicles, existing cubicles may be transferred from MCC-4C5 to the new MCC.
If it is determined that the new MCC will not bs compatible with the existing cubicles, then new cubicles will also need to be purchased.

- De-energize, disconnect and remove old MCC-4C5 i Install new MCC in location of old MCC-4C5
- Connect cabling to new MCC cubicle assemblies
- Test each load to ensure proper operation
- b. Use available sections of MCC-3C4C-2 at MCC-4C5 Much of MCC-3C4C-2 has been abandoned (due to water plant abandonment) and several entire sections are available for use.
Feasibility of this option would need to be explored when MCC-
- 3C4C-2 is available for inspection.

RECOMMENDATIONS FOR CABLE INSPECTIONS 1.) Perform a 100% inspections of all cables (36 total) in cable tray T5.
These are all instrumentation and control cables for the control valves and stop valves. Kevin Naser is determining the tests and procedures l
' that will exercise the valves and insure the associated instrumentation / control signals are functioning properly. Attachment I lists the cables in tray T5.
2.) Perform a complete visual inspection and 33% megger inspection of the 480VAC power cables in cable tray T6 which is located north of MCC-4C5.
l There are a total of 56 cables in sections P4, P4A, and P3 of tray T6.
l Emphasis will be placed on meggering the pump and ' fan motor loads versus i the valve motors. If problems are found, the scope of cables to be meggered will be adjusted accordingly. The selected cables to be meggered are as follows:

3.) Instrumentation and control cable in cable tray T6 will be visually inspected for signs of damage and cracking. No megger tests are i
I
proposed for these low voltage cables unless damage is visually ~
observed.
4.) Electrical junction boxes in the area of the steam line rupture and -
immediately below will be inspected for signs of excessive moisture and to dry out the boxes as necessary. All boxes north of the condenser on the 1011' level shown on drawing Il436-E-283 will be inspected. Push button stations in this area will also be checked. Chuck Schaffer is
! identifying these boxes and push button stations.
