Mr. C. D. Frizzle, President Maine Yankee Atomic Power Company 83 Edison Drive Augusta, Maine 04336.
Dear Mr. Frizzle:
SUBJECT:
SUBMITTAL CONCERNING 2700 MWTh OPERATION AT MAINE YANKEE By letter dated December 28, 1988,'you submitted a proposed change to your Facility Operating License NO. DPR-36 concerning 2700 MWTh operations at Maine Yankee.
By telecon March,3, 1989, Mr. S. Evans of Maine Yankee Atomic Power Company informed the undersigned that.a proposed changed. Technical Specification page 3.10-3 (enclosed) was inadvertently enclosed with your December 28, 1988 submittal. That page is being returned to you.
..If you have any questions, please contact the undersigned at 301-492-1437.
Sincerely, Original signed by:

ENCLOSURE I
1 j.,
2.
the total radial peaking factor, defined as T
P (1 + T )
FR-FR q
shall be evaluated at least once a month during power operation above-50% of rated full power.
2.1 FR is the latest available unrodded radial peak determined from the incore monitoring system for a condition where all CEAs are at or above the 100% power insertion limit.
T is given q
by the following expression:
Tg
,2 (Pa-Pc)2, (ph_pd)2 (Pa+Pb
+ Pc+Pd)Z where Pi is the relative quadrant power determined from the incore system for quadrant i, when the incore system is operable.
If the incore system is not operable, the Pi are the signals from excore detector channels i.
T 2.2 If the measured value of FR exceeds the value given in Figure 3.10-4, perform one of the following within 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s:
1.
Reduce the allowable PDIL insertion (Figure 3.10-1) symmetric offset LC0 (Figures 3.10-8 and 3.10-9) and trip band (Figure 2.1-2), thermal margin low pressure trip limit (Figures 2.1-1 a and b and Technical Specification 2.1), linear heat rate limits *
(Figure 3.10-11) and excore LOGA monitoring limits (Figures 3.10-2 and 3.10-3) by a factor greater than or equal to:
T T
[FR measured] / [FR Figure 3.10-4]
DE:
2.
Reduce thermal power at a rate of at least 1%/ hour to bring T
the combination of thermal power and % increase in FR to within the limits of Figure 3.10-5, while maintaining CEAs at or above the 100% power insertion limit.
If incores
]
are not operable and Figure 3.10-2 is in use, then also reduce excore LOCA monitoring limit (Figure 3.10-2) by a factor greater than or equal to:
s T
T
[FR measured] / [FR Figure 3.10-4]
