, OESCRIPTION AND SAFETY ANALYSIS OF PROPOSED CHANGE NPF-28-125 This change affects the specified values for the degraded voltage protection relays appearing in Table 3.3-4 item 0(c), Table 3.3-5 item 10. and the minimum voltage output for the Emergency Diesel Generator in surveillance requirement 4.8.1.1.2.
Existina Soecifications See Attachment A Pronosed Soecifications See Attachment B Descriotion The following Technical Specification changes are proposed to improve the protection of the Class 1E electrical equipment from degraded voltage conditions.
- 1. In Specification 3/4.3.2, Table 3.3-4: Engineered Safety Features Actuation System Instrumentation Trip Values, the
" trip value" and " allowable values" for tb7 4.16 KV Emergency Bus Undervoltage (Degraded Voltage) are being changed from 2 3640 volts and 2 3604 volts to 2 3875 volts and 2 3860 volts, respectively.
- 2. In Spec 2 fication 3/4.3.2, Table 3.3-5. Engineered Safety Features hesponse Times, the 4.16 KV Emergency Bus Undervoltage (Dograded Voltage) " Response Time In Seconds" is being changed from $ 11 seconds to $ 14 seconds.
- 3. In Specification 3/4.8.1: A.C. Sourcas, tb' facrgency Diesel Generator minimum voltage of surveillanza requirement 4-8.1.1.2 paragraphs ao4, d.1, d.3.b, d.4, d.5.b, and d.6 is being changed from 4160 t 420 volts to 4160 + 420, ~240 volts.
The above noted changea resulted from an issue raised during the Electrical Distribution System Punctional Inspection (Inspection Report Violation 382/9023-01). The NRC, in reviewing protective relaying, concluded that, the Tecnnical Specification " trip setpoint" and " allowable value" for the 4.16 KV bus degraded grid relays were too low to ensure proper operation of all Cltss 1E equipment (i.e., downstream loads) had the bus voltage degraded to a value slightly above the established setpoint. In addition, the NRC found that the existing G.E. NGV degraded voltage relay had excessive drift due to the adjustment potentiometer. In response to this concarn Waterford 3 imposed interim corrective action in Standing Instruction 91-02. Additional corrective action involved installation of new solid state relays (i.e.
during Refuel 5), conducting load flow and voltage drop analyses, 1
1
. and selecting trip sotpointo to accommodato oporation of electrical equipment down to 320V level under varying-grid conditions. For additional details concerning this item, see Waterford 3 submittal W3F1-91-0298 dated May 10, 1991.
The Technical Specification for the degraded voltage relay and timer setpoints provide for degraded voltage conditions to be recognized and corrected such that the safety-related loads do ,
not experience voltages outside their ratings for any sustained l period of time. When the normal offsite power supply to the 4.16 KV safety related bus (es) becomes degraded and voltage falls to an unacceptable level, the degraded voltage relays will separate the 4.16 KV safety related buses -from the offsite electrical supply, start the diesel generatorn, and load the Engineered Safety Features equipment to the bus. The degraded voltage !
protection system time delay accommodates the voltage drops, 4 resulting from starting motors, by blocking actuation of the l degraded voltage protection system. If, during this time delay, the bus voltage recovers to a level above the degraded voltage protection system's reset setpoint the system will ver75 *nd rd further action will ensue.
Branch Technical Position (BTP) POB-1 "Adequi.s/ .
7t? m #
Electrical Distribution System Voltages," pf SH'#f> -q, '($ ceria for determining adequate degraded voltage p t cp- q.t *;cerford l 3 has conducted an engineering review and rs;>.tsj" V . the !
Electrical Distribution System, which meets th. L. ent of BTP I PSB-1 in order to establish the technical specification trip setpoints and allowable values for the degraded voltage relays. ,
The analysis also considered the information provided by NRC l Information Notices 84-02, 89-83 and 91-29 which pertain to degraded voltage.
The new analysis established a technical specification " allowable value" of 3860V (92.8% of 4160) and a " trip value" of 3875V (93.1% of 4160V). The allowabic value is based on the minimum voltage required by safety related equipment plus voltage compromised by equipment inaccuracy. The " trip value" is based on the " allowable value" plus the relay drift value.
The degraded voltage " Response Tiae In Seconds" in specification Table 3.3-5 is based on the relay timer setpoint. The degraded voltage relay timer setpoint is based on motor acceleration times. The analysis determined the maximum motor acceleration time to be 11.1 seconds. This value was subjected to the timer tolerance of 10% resulting in a value of 12.2 seconds. The 12.2 seconds value was rounded to 12.5 seconds for the nominal setpoint. The setpoint (12.5 seconds) was again subjected to the 10% tolerance to acconmodate for potential positive drift resulting in 13.75 which was rou: led to 14 seconds.
The analysis evaluated the impact on running motors at a voltage value slightly above the loss of voltage trip for the extended time delay to determine any detrimental effects and concluded that running motors would not stall and motor qualification would I
not be adversely impacted.

Tho roviccd estpoint and rcost voluco of tho dcgred:d voltcg3 relay impact technical specification surveillance requirement 4.8.1.1.2, which in part assures that the minimum voltage output of.the Emergency Diesel Generator (EDG) is adequate. The current minimum voltage of 3740V will be changed to 3920V or 4160-240.
This will ensure the degraded voltage relay will reset under the worst equipment drift and inaccuracy condition. It should be noted that the EDG primary and backup voltage regulctors are capable of maintaining the output voltage to within .5% (i.e.,
4160 +4180 -4140).
The Technical Specification changes identified above are supported by the new analysis and dependent upon several modifications to the Electrical Auxiliary System as briefly described below:
- 1) The Control Element Drive Mechanism (CODM) fans presently Su not trip upon initiation of an Safety Injection Actuatiu.
(SIAS) signal. The control logic will be changed to trip "'
all four CEDM fans upon initiation of an SIAS signal. i CEDM fans are nonsafety and credit is not taken for thJ r availability during an accident. I6athe CEDM fan were nos tripped, the degraded voltage setpoint would be higher and potentially subject the degraded voltage relay to inadvertent trips.
l 2) The three heater drain pumps will be tripped upon actuation of a generator lockout relay. The heater drain pumps are not required for safe shutdown. If the heater drain pumps were not tripped the degraded voltage relay would trip at a grid voltage slightly below the normal minimum voltage.
Thus, tripping the heater drain pumps will allow the grid to i degraded to a value well below the normal minimum grid l voltage without tripping the degraded voltage relai.
- 3) The safety-related transformers for Power Distribution Panels 360/394-SA, 361/395-SB, 362-SAB, 3004-SA and 3005-SB will'have their tap setting changed from center to -fa.
This tap setting will improve the 120V system voltage to an acceptable value during a degraded voltage condition.
- 4) The present degraded voltage computer alarm will be modified to include an annunciator window which will alarm prior to l
! tripping the degraded voltage relay. This annunciator will warn the operator of a potential _ trip due to degraded L
voltage and to avoid starting any motors.
! 5) The load on the power distribution panel 360-SA will be l
balanced to provide a uniform voltage drop at the 120V syatem. This will improve the 120V system voltage to an acceptable value during a degraded voltage condition.

- 6) The existing G.E.-NGV olectromschanical and agastat timing relays will be replaced with ABB 27N electronic relays. The existing G.E..NGV relay were found to have excessive drift due the calibration potentiometer.- The new relays have a self test feature and a " target" to indicate the relay has tripped; a feature not_present on the existing relay. The electronic relays are more accurate (i 0.1%) and will be set to-reset at approximately 0.4% (ISV) above setpoint.
- 7) To improve voltage at-the starter coils and other auxiliary devices (120V relays, solenoids, etc.) some control cables will be paralleled or the existing control power transformer will be replaced with_a larger transformer. This will improve the voltage at the starters and auxiliary device (relays, solenoids, etc.) to an acceptable value during a degraded voltage condition.
In addition, administrative controls will be placed on the following in support of information provided by NRC Information Notice No. 84-02, " Operating Nuclear Power Plant at Voltage Levels Lower Than Analyzed."
- a. A minimum main generator voltage while supplying the auxiliary equipment from the unit auxiliary transformer
- b. A minimum grid voltage will be required while synchronizing the emergenz:y diesel generator with offsite power to ensure the degraded voltage alarm is not inadvertently actuated.
Safety Analysis The proposed change described above shall be deemed to involve a significant hazards consideration if there is a-positive finding in any of the'following areas:
- 1. Will operation of the facility in accordance with this
- proposed change involve a significant increase in the l probability or consequences of any accident previously evaluated?
Response: No The degraded voltage relay is used to assess whether adequate voltage is available to operate electrical class lE l equipment._ If sufficient voltage is not available within a specified period of time the class 1E and non-Class 1E buses will be separated which will result in the emergency diesel generator starting and loading. The proposed technical specification change will increase the voltage and timer setpoints of the degraded voltage relay to adequately protect all Class 1E elsctrical equipment at the 4.16 KV, 480V and 120V level.

occurrenc3 of a d grad:d voltcga 10 not p2rt of cny liniting accident previously evaluated. Therefore, this change which modifies degraded voltage relay setpoints cannot change the consequences of any limiting accident.
A review of anticipated operational occurrences (ADO, moderate frequency and infrequent ircidents) documented in Chapter 15 of the FSAR indicates that none of these incidents are affected by the degraded voltage relay delay time. Therefore, occurrence of a degraded voltage condition simultaneously with an ADO or during the course of an AOO will have no significant impact on the sequence of consequences of these events.
Replacement of the existing General Electric electromechanical NGV degraded voltage relays with the more accurate ABB Brown Bavari 27N Electronic relays will increase the reliability and will not affect any accidents previously evaluated. The replacement relays are Class 1E and will be eble to withstand a seismic event as defined in the Final Safety Analysis Report (FSAR).
( Power Distribution Panel (PDP) transformer tap setting will l
be changed to increase (improve) voltage of the 120V Class 1E voltage system during a degraded voltage condition. This increase in voltage will allow Class 1E equipment supplied l
from these PDPs to operate within their specified voltage l range. Changing these transformer taps will optimize L voltage levels and will have no impact on accidents creviously evaluated.
Class 1E starter and auxiliary device (i.e. relays, l solenoids, etc.) control circuits will be modified (i.e.
parallel conductors / replace control transformer) to improve the voltage at the lE device to allow pickup _during a degraded voltage condition. Changing these control circuits l will have no impact on accidents previously evaluated.
l l Balancing the load on the power distribution panel 360-SA to provide' uniform voltage at the 120V system will have no impact on accidents previously evaluated.
I Lastly, modification to the CEDM fan and heater drain pump control circuits will have no impact on postulated accidents, since this equipment is nonsafety.
The above proposed changes will have no negative impact on the reliability or performance of Class lE equipment protected by the degraded voltage relays. Therefore, the I
proposed change will not involve a significant increase in the probability or consequences or any accident previously evaluated.

- 2. Will oporation of the facility in accordance with this proposed change create the possibility of a new or different l kind of accident from any accident previously evaluated?
Response: No The proposed technical specification changes and the modifications noted above in Item #1 to support the proposed change are designed to improve the present protection of Class 1E electrical equipment during a degraded voltage condition. Improvement of the present protection scheme dres not involve a change in the design of the degraded vo tage function. The degraded voltage protection scheme will continue to use a 3 out of 3 logic to separate the Class 1E from the non-Class 1E electrical distribution system and to start and load the emergency diesel generator.
Because the proposed amendment will not change the design, function or method of operation of Class 1E equipment at Waterford 3, it will not create the possibility of a new or different kind of accident from any previously evaluated.
- 3. Will operacion of the facility in accordance with this proposed change involv; a significant reduction in a margin of safety?
Response: No The proposed technical specification changes and the modifications noted above in Item #1 are designated to improve the present protection of Class 1E electrical equipment during a degraded voltage condition. These changes will have no adverse impact on protective boundaries or safety limits. Therefore, tne proposed change will not involve a significant reduction in a margin of safety.
The Commission has provided guidance concerning the application of ^3ndards for determining whether a significant hazards consideration exists by providing certain examples (48 FR 14870) of amendments that are considered not likely to involve significant hazards considerations. The changes identified in this submittal closely match example (ii):
(ii) A change that constitutes an additional limitation, restriction, or control not presently included in the technical specifications, (i.e., a more stringent surveillance requirement) ;
Safety and Sionificant Hazards Determination Based on the above safety analysis, it is concluded that: (1) the proposed change does not constitute a significant hazards consideration as defined by 10 CFR 50.92; and (2) there is a reasonable assurance that the health and safety of the public will not L2 endangered by the proposed changes; and (3) this action will not result in a condition which significantly alters the impact of the station on the environment as described in the NRC final environmental statement.
