NRC INFORMATION NOTICE NO. 89-50' INADEQUATE EMERGENCY DIESEL GENERATOR FUEL
SUPPLY
Addressees
All holders of operating licenses or construction permits for' nuclear power
reactors.
Purpose
This information notice is being provided to alert addressees to the potential
for existence of an Inadequate emergency diesel generator (EDG) fuel supply.
It is expected that recipients will review the information for applicability
to their facilities and consider actions, as appropriate, to avoid similar
problems.
However, suggestions contained in this information notice .do not
constitute NRC requirements; therefore-, no specific action or written response
is required.-
Description of Circumstances
Duringia review of the 'design basis for the EDGs at Palisades, it was dis- covered that the fuel oil consumption calculations, performed in 1968, had
not been updated to reflect changes in equipment loading and operating times
in post-accident conditions. Subsequent calculations by the licensee indicated
that 23,000 gallons of diesel fuel would be required to ensure that a seven day
supply would be available to support EDG operation under the current load
requirements. This value exceeds the minimum 16,000 gallon limit specified
in the Technical Specifications (TS). The licensee's corrective actions in- cluded prescribing a higher administrative--limit of 23,000 gallons of fuel and
performing additional calculations to support a TS change request. This is
discussed further in licensee event, report (LER) 50-255/89-005.
A discrepancy between the Final Safety Analysis' Report (FSAR) and the TS basis
was identified at Robinson Unit 2. The TS basis specified that 25,000 gallons
of fuel oil be maintained for operation of one EDG carrying "minimum safety
features" load for seven days. The FSAR described the 25,000 gallons as suf- ficient for one EDG carrying "full load" for seven days.. Calculations performed
by the licensee indicate that 25,000 gallons is only marginally sufficient for
one EDG carrying 'minimum safety features" load for seven days since fuel
consumption is highly dependent on selective load shedding.
The licensee's
89053021
K)
IN 89-50
May 30, 1989 calculations also indicate that one EDG carrying "full load" for seven days
would require approximately 30,430 gallons.
The licensee's corrective actions
included redefining the basis for the seven day fuel supply to the more con- servative value (operation of the EDG at its rated capacity) and revising
the TS to reflect the increased minimum fuel inventory.
This is discussed
further in NRC Inspection Report No. 50-261/87-06 and in LER 50-261/88-006.
The McGuire FSAR indicates that the underground storage tank for each EDG is
sized so that the corresponding EDG can carry the 4160 Volt Essential Auxiliary
Power Systems load for seven days. The TS require that each underground storage
tank contain a minimum volume of 28,000 gallons of fuel.
Recently, it was
discovered that 28,000 gallons is not sufficient to ensure seven days of EDG
operation. The licensee has Indicated that design calculations show that appro- ximately 48,533 gallons of fuel are needed to ensure seven days of operation at
rated load. This is discussed further in NRC Inspection Report No. 50-369/89-02.
Discussion:
Regulatory Guide 1.137, "Fuel Oil Systems for Standby Diesel Generators,"
contains guidance for calculation of EDG fuel oil storage requirements.
Two methods are provided: 1) calculations based on the assumption that
the EDG operates continuously for seven days at its rated capacity and
2) calculations based on the time-dependent loads of the EDG (which should
include the capacity to power the engineered safety features).
No specific action or written response is required by this information notice.
If you have any questions about this matter, please contact the technical
contact listed below or the Regional Administrator of the appropriate regional
office.

May xx, 1989 licensee's calculations also indicate that one EDG carrying "full load" for
seven days would require approximately 30,430 gallons. The licensee's cor- rective actions Included redefining the basis for the seven day fuel supply to
the more conservative value (operation of the EDG at its rated capacity), and
revising the TS to reflect the increased minimum fuel inventory and the basis
for the seven day fuel supply.
This is discussed further in NRC Inspection
Report No. 50-261/87-06 and in LER 50-261/88-006.

approximately 48,533 gallons of fuel are needed to ensure seven days of opera- tion at rated load. This is discussed further in NRC Inspection Report No.
50-369/89-02.
Discussion:
NRC regulations require that an onsite electric power system and an offsite
electric power system be provided to permit functioning of structures, systems, and components important to safety. Methods acceptable to the NRC staff for
complying with the NRC's regulations regarding EDG fuel oil systems are de- scribed in Regulatory Guide 1.137.
Regulatory Guide 1.137 indicates that the
two methods acceptable to the NRC staff for calculation of fuel oil storage
requirements are 1) calculations based on the assumption that the EDG operates
continuously for seven days at its rated capacity and 2) calculations based on
the time-dependent loads of the EDG (which should include the capacity to power
the engineered safety features).
It is important for addressees to determine
the existence of an adequate emergency diesel generator fuel supply.
