Conditions of License My letter L-76-233 to you dated June 22, 1976, provided in-formation pertaining to demonstration that the requirements of Conditions of License E.l and E.2 have been satisfied.

My letter L-76-239 to you dated June 28, 1976, provided a

commitment to remove the temporary earthen construction dike associated with construction of the permanent, ultimate heat sink (UHS) barrier dam required by Condition of License E.2 by July 31, 1976.

i Information concerning FPL compliance with Condition of License E.3 was forwarded to you by my letter L-76-227 of June 14, 1976.

Information concerning Condition of License E.4 was forwarded to you by my letters L-76-208 and L-76-222, dated June 14,

1976, respectively.

A commitment to modify the St. Lucie Plant Security Plan to address the items transmitted to FPL by Mr. R.

D. Silver of your office by telecon on June 23,

1976, was provided in my letter L-76-237 to you dated June 25, 1976.

On June 29,

1976, a meeting was held between Florida Power 6

Light Company and the Nuclear Regulatory Commission Staff in Bethesda to review the status of St. Lucie Unit No.

1 Condi-tions of License, E.l, E.2 and E.3.

As indicated

above, the requisite information concerning UHS erosion protection (Condition E.l) and the UHS permanent barrier dam (Condition E.2) has al'ready been supplied which, we believe, fulfillsour June 30, 1976, requirement to satisfy these two license conditions.

We also agree to provide, by August 31,

1 Conditions of License June 30, 1976 Page of the sheetpile groins and bulkheads requested by the Staff in the June 29, 1976 meeting.

Until this supple-mentary information is provided and reviewed by the Staff, the following interim operational action will be established:

If a hurricane or a tropical cyclone landfall is predicted for eastern and southern Florida, FPL will notify the Nuclear Regulatory Commission.

The Facility Review Group will assess whether or not power operation of St. Lucie Unit No.

1 is to be continued.

Continued power operation will be with the concurrence of the Company Nuclear Review Board.

The requisite information concerning the balance of plant electrical equipment QA audit (Condition E.3) has been supplied as indicated

above, thus fulfillingour June 30, 1976, requirement on this condition of license.

Additional information regarding containment fan cooler motor qualifi-cation presented to the Staff in the June 29, 1976, meeting at their request is also enclosed.

We intend to also pro-vide the Staff with further information regarding the ana-lytical techniques employed in the seismic analysis of the containment fan cooler units by August 31, 1976.

On the basis of the above, FPL believes that it has satisfied all of the conditions contained in Section E of Enclosure 1

to the St. Lucie Unit No.

1 Operating License, and hereby requests that Section E be deleted and that authorization for operation beyond June 30,

1976, be granted.

regulatory Docket File REACTOR CONTAINMENT FAN COOLER MOTOR GENERAL DESIGN PHILOSOPHY The design of the Reactor Containment Fan Cooler Motor results from a series of'equirement and selection processes which begins with a selection of the "overall" Reactor Containment Fan Cooling System Design.

Once the overall system has been identified, the main cooling coil heat exchanger requirements are established.

These requirements are based on containment temperature requirements for normal, accident and/or post accident conditions, whichever is limiting.

Following the establishment of the main cooling coil requirements, a fan design is chosen to be coupled to the main coil.

At this point the fan blading and fan speed are selected as part of the overall fan design.

Based on the selection of fan design and'ontainment cooling requirements, the fan horsepower motor requirements are determined for all three operating conditions (normal, accident and post accident).

The motor designer then selects an adequate motor frame for the intended load application.

The motor. designer calculates the motor losses including the steady heat loss which must be removed to maintain normal winding temperature:

This total kilowatt loss taken together with the shaft driven fan pressure-volume curve and cooling water temperature establishes the motor heat exchanger design.

Electrical motor characteristics,'uch as efficiency, are then calculated and verified after the windings have been selected to meet specified horsepower, rise and torque valves.

In specifying the design features of the motor, the checklist provided in response to question 1 below is utilized to insure MCAP?829 applicability.

Specific motor heat exchanger requirements for St. Lucie's an cooler motors are provided in response to question 3 below.

~

~

Westinghouse has stated the motors qualified by WCAP 7829 had a

NEHA frame 588.5.

PSL-1 has a frame size 5010L.

Provide motor characteristics changes, if'ny, for PSL over motor qualified by Westinghouse due.to frame changes.

~Res onse:

Table 3 is a listing of the specific electrical motor characteristics associated with PSL-1 Frame 5010L and WCAP Frame 588.5.

It should be noted that WCAP Frame 588.5 has an ultimate 600 HP 2 or 4 pole capability and has been used up to a 300 HP capability for containment fan coolers in various plants (see Table of FPL Submittal of 6/14/76).

The PSL-1 5010L Frame has an ultimate 700 HP 2 pole capability and is used at St. Lucie to a 150 HP maximum design basis profile, thus being applied considerably more conservatively.

The PSL-1 design features shown in attached Table 1 list the motor design features required to comply with motor post accident WCAP 7829 qualification profile and are noted with references to document their conculsion in the design of the PSL-1 motor.

As noted in Table 1, these design features are qualified per Table 2 of WCAP 7829.

(Page 10).

Current, efficiency, power factor and other electrical characteristics (see Table 3) are calculated and verified after frame/winding/horsepower/temp.

rise/torques are chosen for the specific application.

Calculations are based upon commonly known motor. design expression which have been specifically verified by actual complete factory tests for the PSL-1 machine.

Results of these tests are shown on attached Westinghouse 9/21/73 Factory Test Data.

I The purpose of this analysis is to verify the structural integrity of I

I the reactor fan coolers when subjected to seismic loads.

IIETHOD The fan motor system spring constants and natural frequencies were calculated (see Table 1).

All frequencies except fan rotor are above the rigid range (33 cps).

The rotor (24.6 cps) is close to rigid range H

and its second natural frequency (153.5 cps) is very high.

Therefore

.its response in characteristics is one made dominant.

From the acceleration spectra curves for period

.041 sec it is assembly has the same frequency as in the rigid zone.

are in the region of zero amplification the fan motor seen that the rotor Because all frequencies system was analyzed using seismic equi valent s tati c 1 oads.

The coils and coil ban..s are also rigid and were analyzed as such.

. The seismic load levels. were established using the defined seismic criteria for. Hutchinson Island.

The folio.zing DBE accele'ration values were used:

I Vertical Sei smi c 0.8 g

Horizontal Seismi c Elev.44'lev.

60'.2 g

• 1.2 g

The vertical and horizontal seismic loads were applied simultaneously in the worst possible manner.

In addition the coils were subjected to a

differential pressure of 2 psi to represent the blowdown transient pressure di fference,

I I

Stresses and deflectior s were calcuIated using elastic'relations for the worst combination of operating loads, horizontal seismic (DBE),

I vertical seismic (DBE), and accident pressure (coils arid coil banks).

Limit valu s used were in. accordance with the elastic provisions in'

~

the AISC-69 and ASHE Sec. VIII Pressure Vessels Specifications (latter primarily for coil tube and fin material).

RESULTS The calculated and limit behavior along with factor of safety values for different modes of failure are given in Table 2.

OBE seismic loads were used f'r calculated values in Table 2.

Since the elastic limits, associates with an OBE event, were not exceeded when OBE seismic 'ievels were used is not necessary to perform an OBE seismic analysis.

COI)CLUSI 0!(S Based upon the seismic analysis the fan system, cooling coils arid coil ll banks can more than support the maximum earthquake (DBE) loads in combination with operating and accident loads called for in the specifications.

The a ove>>ill remain elastic under specified maximum loads.

The desi gn, there fore, i s adequate.

The'enclosure seismic analysis was prepared by Shaffer Engineering and is given in a separate report.

A letter from J.

Irons of dune 14, 1976, states that the table "Typical Motor Design Parameters Compared to Test Machine" shows an insulation peak temperature of 105.8 C for worst case DBA conditions.

Heat which must be removed from PSL-1 fan cooler motor windings is 1.) added heat from outside DBA 'conditions 2) added heat generated internal to winding due to fan cooler load.

The motor in MCAP 7829 demonstrates only that the heat from outside DBA conditions plus the heat resulting from current o'f 26.1 Amps can be removed by the heat exchanger.

Provide results of heat exchanger analysis to demonstrate the PSL-1 motor insulation temperature W.71 remain within 105.8'C for worst case DBA conditions plus full load current of 200 amperes.

~Res onse Due to the number of variables for each plant (i.e. cooling water temperatures, containment temperatures, motor losses, etc.) the heat exchanger must be specifically sized for its particular application.

This is accomplished by use of a computer code developed for this purpose.

Copies of the computer print out for the heat exchangers used in the St. Lucie motors are listed as'tem 1 thru 6.

Items 1

and 2 ar' for normal operation, 3 and 4 for DBE operation and 5 and 6 for post DBE operation.

s Additionally, Figures 1, 2, and 3 show the air flow pattern through the motor and heat exchanger indicating the heat exchanger inlet and exhaust temperatures for normal (Figure 1),

DBE (Figure 2), and Post DBE (Figure 3) operation.

Performance of the heat exchanger is predicted by a computer program.

It has been verified by standard ARI coil certification tests.

Heat and mass transfer occuring on the surface of base enclosure and motor are based on standard 'correlation for free convection heat transfer and "COLBURN ANALOGY" between heat and mass transfer.

Heat transfer of the interior of base enclosure is based on the standard "COLBURN RELATIONSHIP" for turbulent forced convection in an enclosed space.

Heat transfer between the outside of the motor frame and air passing through the motor is based on a computer program developed to predict the heat transfer performance for electric motors of this type.

The attached print outs are computer out put for normal and POST LOCA operation of heat exchanger for PSL-l. It should be noted that the heat exchanger is suitable for the worst environment of, DBA condition, (Items 3 and 4), which includes the maximum heat losses of the motor associated with its increased horsepower requirements during DBA operation.

Under normal and POST DBA operation, performance of the heat exchanger greatly exceeds the heat removal requirements.

From data given in table "Typical tlotor Design Parameters Compared to Test t'lachind" explain apparent discrepancy'of inlet air temperature to insulation ('F) under item 5 for the test machine, and the inlet air ('C) under item fl, motor parameter s (e.g.,

100'F r 76'C).

In addition please justify variation between motor parameters:

inlet air 'C rise of insulation 'C total temperature horsepower full load amperes starting torque

~Res oose During normal plant operation the heat exchanger output to the fan cooler motor unit is in the order of 100'F (~38'C).

However, the test plan for the motor called for producing realistic total temperature rise (inlet air + insulation rise) by varying inlet air temperature to the motor and/or varying motor loading.

Since the test machine had a fixed blading (loading) configuration inlet air temperature to the motor insulation was increased.

This was performed by circulating heated water through the heat exchanger.

For example, in a test under normal room conditions the fan load raised the winding temperature only 16'C; consequently, the heat exchanger water temperature was increased until the heat exchanger output (motor intake) was 76'C giving a total temperature rise of 92'C, i.e. inlet air (76'C) plus loading (16'C).

As previously mentioned in normal applications the heat exchanger output (air inlet to the motor ) is of the order of 100'F (~ 38'C).

This allows for a motor temperature (winding) rise on the order of 60'C during normal operation (Class A application of Class F insulation).

The variation in motor parameters as shown in the previously submitted Table, "Typical Motor Design Parameters Compared to Test thachine" result from the individual motor design application requirements.

However, as indicated in response to guestion 1 above, specific conditions, requirements which the motor design must provide in order to have

>ICAP 7829 applicability have been included in the fan cooler motors supplied to St. Lucie.

lIore specifically the motor thermal design for the individual application is first established then the electrical characteristics follow.

Motor design requires calculation of 5 separate losses which account for internal rise of the motor and a steady heat loss which must be removed.

This total kilowatt loss taken together wi th the shaft driven fan P-V curve and coo'ling'"water temperature permit the heat exchanger designer to arrive at an air outlet (motor inlet} temperature.

The motor internal rise plus the inlet air gives the total temperature at any horsepower.

Current, efficiency, power factor and other electrical characteristics can be calculated and verified as soon as. windings have been selected to meet specified horsepower, rise and torque values.
