- 1. An entire Westinghouse Large Motor Division thermalastic epoxy insulation system prototype st'ator was thermally cycled.
Temperature ranged from -30*C (in dry ice for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and rapidly raised to 150*C). This was repeated 4 times. The stator wao then immersed in water and the insulation resistance was checked. Insulation resistance prior to test was 9 x 10 4Meg 4
ohms and post test the resistance was 2 x 10 Meg ohms while submerged. (Reference E-9)
In another test, an entire thermalastic epoxy insulation system stator was submerged while energized in both tap water and seit water. Satisfactory performance was demonstrated for 1,000 days in tap water and 200 days in salt water. (Reference E-16)
Thermalastic epoxy insulation system can simultaneously withstand harsh steam envirorseents as demonstrated by a 58.3 day exposure to 100% relative humidity at 122*F. The resulting insulation resistance was 4,000 Meg ohns. Additionally, a tharmalastic epoxy insulation system has satisfactorily passed a 48-hour exposure to 500*C. (Reference E-16)
Based on the above tests, it can be concluded that motors constructed utilizing thermalastic epoxy insulation system would I satisfactorily withstand the postulated steam exposure. The postulated exposure reaches peak values of 145'F (130*F plus j 15'F margin) and 17.66 psia (16.06 psia plus 10% margin). % e transient has a duration of 1450 seconds.

- 1. The component is a lube-oil pump motor which is used in providing lubrication for the high pressure injection pumps. The harsh environment specified for Room 105 is caused by a postulated main feedwater line break in Room 303. The high pressure injection pumps may be required te aid in the HELB accident.
The emergency procedures applicable to the main feedwater line break specify the need for high pressure injection only in response to an overf eeding of the steam generators upon auxiliary feed initiation, thus causing primary system depres9urization. Furthermore, setpoint changes have been made, lowering the steam generator level maintained, to preclude the need for high pressure injection. This lack of required operation of the HPI system would also eliminate the necessity of the lube-oil pump motors.
The elevated temperature and pressure values seen by the lube-oil pump motor are of a relatively short duration and magnitude. Tne pressure spike peaks at 16.06 psia in 1.75 seconds. As a result, the effects of the 100% relative humidity would be negligible due to the small pressure increase and also due to the sealing capability of the motor. The temperature peak of 130*F occurs in 19 seconds but returns to ambient in 24 minutes. The increase in the temperature is not instantaneous as it occurs gradually to the peak and would therefore not impact motor operation. The radiation value ,l cpecified is due to the post-LOCA recirculation of fluids. This recirculation would occur close to or at the end of the l functioning of the high pressure injection pumps if required. Assuming common motor mater {als are used in the lube-oil pump l motor would preclude its failure in the harsh environment since the radiation value is significantly low.
In the highly unlikely event of failure of this pump motor, a redundant HPI train, located in Room 115, is available to mitigate the HELB if required. Although the environment in Room 115 is elevated due to the break in Room 303, the temperature peaks at only 99'F, and the pressure peaks at only 15.6 psia (see CAL-35). These values are less than those in Poom 105, and they are very close to being considered non-harsh. This fact introduces a significantly higher probability of the component remaining f unctional. Based on our discussion above and coupled with the likely availability of a redundant HPI train, interim operation is justified.
- 2. One-year operating timo is used as a conservative maximum specification.
- 3. This component will be replaend with a qualified motor in accordance with FCR 83-062.

4 The emergency procedures applicable to the main feedwater line break specify the need for high pressure injection only in

This lack of required operation of the HPI system would also eliminate the necessity I of the lube-oil pump motors.
I The elevated temperature and pressure values seen by the lube-oil pump motor are of a relatively short duration and magnitude. The pressure spike peaks at 15.6 psia in 1.7 seconds. As a result, the effects of the 100% relative humidity would be negligible due to the small pressure increase and also due to the sealing capability of the motor. The temperature 3
peak of 177'F occurs in 19 seconds but returns to ambient in 6.7 minutes. The increase in the temperature is not instantaneous as it occurs gradually to the peak and would therefore not impact motor operation.

- 1. The component is a lube-oil pump motor which is used in providing lubrication for the high pressure injection pumps. The hIrgh environment specified for Room 105 is caused by a postulated main feedwater line break in Room 303. The high pressure injtetion pumps may be required to aid in the HELD accident.
Tha emergency procedures applicable to the main feedwater line break specify the need for high pressure injection only in rorponse to an overfeeding of the steam generators upon auxiliary feed initiation, thus causing primary system d: pressurization. Fu rthermore, setpoint changes have been made, lowering the steam generator level maintained, to preclude the need for high pressure injection. This lack of required operation of the HPI system would also eliminate the necessity of the lube-oil pump motors.
Tha elevated temperature and pressure values seen by the lube-oil pump motor are of a relatively short duration and magnitude. The pressure spike peaks at 16.06 psia in 1.75 seconds. As a result, the effects of the 100% relative humidity would be negligible due to the small pressure increase and also due to the sealing capability of the motor. The temperature prak of 130*F occurs in 19 seconds but returns to ambient in 24 minutes. The ir. crease in the temperature is not instantaneous as it occurs gradually to the peak and would therefore not impact motor o.peration. The radiation value specified is due to the post-LOCA recirculation of fluids. This recirculation would occur close to or at the end of the functioning of the high pressure injection pumps if required. Assuming common motor materials are used in the lube-oil pump motor would preclude its failure in the harsh environment since the radiation value is significantly low.
In the highly unlikely event of failure of this pump motor, a redundant HPI train, located in Room 115, is available to mitigate the HELB if required. Although the environment in Room 115 is elevated due to the break in Room 303, the tsmperature peaks at only 99'F, and the pressure peaks at only 15.6 psia (eee CAL-35). These values are less than those in Room 105, and they are very close to being considered non-harsh. This fact introduces a significantly higher probability of the component remaining functional. Based on our discussion above and coupled with the likely availability of a redundant HPI train, interim operation is justified.
- 2. One-year operating time is used as a conservative maximum specification.
- 3. This component will not be scheduled for replacement until it is determined that a fractional horsepower qualified DC motor exists.

- 1. This component is scheduled to be replaced by the first refueling outage subsequent to component on-site availability.
Tha component is a pressure differential indicating switch used to start the de lube oil pump motor which is used in providing lubrication for the high pressure injection pumps. The harsh environment specified for Room 105 is caused by a poetulated main feedwater line break in Room 303. The high pressure inj.ection pumps may be required to aid in the HELB accident.
Tha emergency procedures applicable to the main feedwater line break specify the need for high pressure injection only in ratponse to an overfeeding of the steam generatore upon auxiliary feed initiation, thus causing primary system drpressurization. Furthermore, setpoint changes have been made, lowering the steam generator level maintained, to preclude l tha need for high pressure injection. This lack of required operation of the HPI system would also eliminate the necessity l of the pressure dif ferential indicating switch.
The elevated temperature and pressure values seen by the pressure differential indicating switch are of a relatively short duration and magnitude. The pressure spike peaks at 16.06 psia in 1.75 seconds. As a result, the effects of the 100%
relative humidity would be negligible due to the small pressure increase and also due to the sealing capability of the pressure differential indicating switch. The temperature peak of 130*F occurs in 19 seconds but returns to ambient in 24 minutes. The increase in the temperature is not instantaneous as it occurs gradually to the peak and would therefore not imptet switch operation. The radiation value specified is due to the post-LOCA recirculation of fluids. This recirculation would occur close to or at the end of the functioning of the high pressure injection pusps if required.
In the highly unlikely event of failure of this pressure differential indicating switch, a redundant HPI train, located in Room 115, is available to mitigate the HELB if required. Although the environment in Room 115 is elevated due to the break in Room 303, the temperature peaks at only 99'F, and the pressure peaks at only 15.6 psia (see CAL-35). These values are less than those in Room 115, and they are very close to being considered non-harch. This fact introduces a significantly higher probability of the component remaining functional. Based on our discussion above and coupled with the likely availability of a redundant HPI train, interim operation is justified.
2 Ona-year operating time is used as a conservative maximum specification.
- 3. Materials and/or components sensitive to thermal aging will be replaced as per maintenance and replacement schedules to assure that associated component will maintain functional operability in harsh environments.

Tha component is a pressure differential indicating switch used to start the de lube oil pump motor which is used in l providing lubrication for the high pressure injection pumps. The harsh environment specified for Room 115 is caused by a postulated main feedwater line break in Room 314. The high pressure injection puses may be required to aid in the HELB l cccident.
Tha emergency procedures applicable to the main feedwater line break specify the need for high pressure injection only in rorponse to an overfeeding of the steam generators upon auxiliary feed initiation, thus causing primary system dzpressurization. Furthermore, setpoint changes have been made, lowering the steam generator level maintained, to preclude the need for high pressure injection. This lack of required operation of the HPI system would also eliminate the necessity of the pressure differential indicating switch.
The elevated temperature and pressure values seen by the pressure differential indicating switch are of a relatively short duration and magnitude. The pressure spike peaks at 15.6 psia in 1.7 seconds. As a result, the effects of the 1004 l relative humidity would be negligible due to the small pressure increase and also due to the sealing capability of the pressure differential indicating switch. The temperature peak of 177'F occurs in 19 seconds but returns to ambient in 6.7 minutes. The increase in the temperature is not instantaneous as it occurs gradually to the peak and would therefore not impact switch operation. The radiation value specified is due to the post-LOCA recirculation of fluido. This recirculation would occur close to or at the end of the functioning of the high pressure injection pumps if required.
In the highly unlikely event of failure of this pressure differential indicating switch, e redundant HPI train, located in Room 105, is available to mitigate the HELB if required. Although the environment in Room 105 is elevated due to the break in Room 314, the temperature peaks at only ll2.5'F, and the pressure peaks at only 15.2 psia (see CAL-35). These values are less than those in Room 115, and they are very close to being considered non-harsh. This fact introduces a significantly
