TO Ernie Tullos, Director of Electric Utilities
FROM Jim Thune, Superintendent of Electric Production
DATE December 11, 1990
SUBJECT UNIT 1 & 2 TURBINE SHOP REPAIRS ----------
Attached is a request to fund emergency repairs to Units 1 & 2 steam
turbines Both stop valves assemblies and Unit 2 nozzle block were found
to have defects
The turbine stop valve provides a positive shut off of steam supply to the
turbines in the event of a trip Steam allowed to enter an unloaded
turbine could spin the rotating assembly, uncontrolled to failure This
could happen if the seating surfaces of the stop valve failed Upon
inspection, these surfaces were found to have crack indications in the
valve disks on both units and the valve seat on Unit 1 Further
deterioration is likely if the seating surfaces are not restored
The turbine first stage nozzle block directs steam to the first stage of
rotating blades it provides the initial directional influence on steam
entering the turbine casing and thus has a significant influence on overall
turbine efficiency The nozzle block on Unit 2 has severe partition
erosion and crack indications in several key support areas Continued
operation could result in decreased nozzel performance and/or failure of
the component resulting in steam path destruction
Both of these areas require attention at this outage to insure the
reliability of the machines Although present repair is costly, the
consequence of future failure is much greater in terms of repair and lost
generation/capacitY
During the last two Winter operation periods, all available units were
dispatched for operation Last year on December 23, 1989, Pool generation
nearly fell short of load requirements during severe cold weather
Expediting the approval for this funding is encouraged to restore unit
availability in early January 1991 This availability could be required by
the Pool if severe cold weather operation is again dispatched
Unit I & 2 Repairs
Page 2
Finally, General Electric could perform these repairs and we have approved
purchase orders in place to fund shop repairs General Electric will
perform the nozzle repairs for $12,000 00 The contract shop quoted
$7,100 00 for nozzle repairs General Electric did not provide a quote for
reconditioning the stop valve components They would quote new pricing
totalling approximately $14,000 00 for parts only, not installation, with a
25 week delivery The contract shop will recondition the stop valve
components for approximately $6,500 00, turn -key in 2 weeks In the event
the stop valve components cannot be reconditioned, new components can be
reverse engineered for approximately $16,000 00 installed Regardless of
repair option, the contract shop offers lower total cost The contract
shop workmanship and warranty are acceptable and comparable to General
Electric shop repairs
I recommend that we seek approval for this funding based on emergency need
and direct the contract shop to proceed with repairs

TOTAL AMOUNT $30,974 65
RECOMMENDATION We recommend this emergency purchase order
to AP Water Supply in the amount of $30,974 65 be approved
for payment
SUMMARY This emergency purchase order is for water system
repair and maintenance items stocked in the City of Denton
Warehouse The normal stock levels for these items were
repidly depleted due to a large number of water line breaks
and numerous other water service problems related to the
recent extreme cold weather Sufficient time to bid these
items was not available due to the arrival of additional
extreme cold weather Prices were solicited by phone quotes
and the order issued to the vendor with the lowest prices
The quantities listed on P 0 #11569 will bring these repair
materials back to necessary stock levels This purchase
will help assure availability of supplies for field service
crews to make emergency repairs so that water utility
service is disrupted as little as possible
