Review all aspects of the safety grade auxiliary feedwater system to further upgrade couponents for added reliability and performance. Present modification will include che addition of dynamic braking on the auxiliary feedpump turbine speed changer and provision of means for control room verification of the auxiliary feedwater flow to the steam generators. This means of verification will be provided for one steam generator prior to startup from the p~ resent maintenance outage and for the other steam generator as soon as vendor-supplied equipment is available (estimated date is June 1, 1979). In addition, the licensees will review and verify the adequacy of the auxiliary feedwater system capacity.
Response
Toledo Edison has provided its review of the overall reliability of the auniliary feedwater system installed at Davis-Besse Nuclear Power Station, Unit 1 (DB-1) with regard to its operating history and associated design improvements in Enclosure 1 to our letter of May 23, 1979 (Serial No. 508). This assessment, combined with past reliability improvements, the safety grade redundant train design and the safety grade control of steam generator level independent of the integrated control system (ICS), shows that the system is fully capable of performing its required function. Toledo Edison recognizes the importance of this system for DB-1 and will continue its review as part of our longer term commitment of April 27,1979 (Serial No. 497) and later documented by the May 16, 1979 Order.
The auxiliary feedwater turbine dynamic braking resistors, as described in Attachment A of our submittal of May 19, 1979 (Serial No. 505) have been installed.
We have also installed the auxiliary feedwater flow indicators on both auxiliary feedwater lines with control room readouts. These two modifications are described in Toledo Edison's letter of May 22, 1979 (Serial No. 507). Enclosed in this transmittal are the testing procedures on both modifications for your review.
With regard to the final portion of this item, Toledo Edison has completed its review of the capacity of the auxiliary feedwater system and verified the adequacy of the DB-1 system to deliver well over the minimum flowrate to a steam generator.
A minimum auxiliary feedwater flowrate of 550 gpm was established for DB-1 from analysis of the loss of feedwater and loss of offsite power transients for general FSAR accident applicability.

June 13, 1979 Docket No. 50-346 License Wo. NPF-3 Serial No. 515 Item IV (1)(a) Response (continued)
The Auxiliary feedwater (AFW) flow is established to cne or both steam generators within 40 seconds of an accident when required. The most severe overheating events requiring AFW are loss of main feedwater flow, main feedwater line breaks and loss of offsite power accidents. For these events, the peak reactor coolant system (RCS) pressures and temperatures will cccur at the time the reactor is tripped. After the reactor is tripped, the RCS temperatures and pressures will go down using the steam generators stored inventory as the heat sink. When AFW flow is started, the RCS rapidly cools down due to the cold AFW flow until the desired steam generator (SG) level is obtained and the SG secondary water tempera-ture has heated up to 550 F (saturation temperature for the code safety valve setpoint of 1050 psig). The mininum auxiliary feedwater flowrate prevents pressurizer fill and saturation conditions in the core and hot legs by limiting RCS overheating.
For auxiliary feedwater flow requirements under small break conditions, Toledo Edison's submittal of May 23, 1979 (Serial No. 508) discussed the model utilization of auxiliary feedwater flow in the small break analysis. This led to your staff's concern that r.he apparent required flowrate capacity was in excess of minimum available for the 700 to 770 second time frane. Figure 1 attached represents the sensitivity of steam generator level to AFW flow capacity and illustrates that, although steam generator level recovery is affected for varying flowrates, only the time to level stabilization is changed. At no time is the heat removal capa-bility of the steam generator impaired.
Figure 1 illustrates a two steam generator feed example of 275 gpm auxiliary feed-water flow per generator, when required, to recover level. Asymetric cooling via one steam generator results in some alteration of system parameters. These are illustrated in section 6.2.4 of Volume I of B&W's report of " Evaluation of Transient Behavior and Small Reactor Coolant System Breaks in the 177 Fuel Assembly Plant" (dated May 7,1979) as not significant with respect to loss of heat removal capability of the steam generator.

Revise operating procedures as necessary to eliminate the option of using the Integrated Control System as a backup means for controlling the auxiliary feed-water system.
Response
The Davis-Besse Nuclear Power Station, Unit 1 (DB-1) design incorporates two safety grade level control systems, one manual and one " Auto-essential" (fully automatic). The facility operates with the " Auto-essential" mode selected, so that whenever an event requires auxiliary feedwater (AFW), the initial response is automatic. A third level control system available by the original design is the integrated control system (ICS). Toledo Edison has removed this mode of operation administratively by prohibiting the use of ICS level control for auxiliary feedwater. Additionally, mechanical stops have been installed on the AFW level control mode selector switches in the control room, allowing only the use of " Auto-essential" and manual modes of operation.

Implement a hard-wired control-grade reactor trip that would be actuated on loss of main feedwater and/or turbine trip.
Response
The design and description of the control grade interim reactor trip system for Davis-Besse Nuclear Power Station, Unit 1 (DB-1) was supplied in our letter of May 11, 1979 (Serial No. 501). The installation of this system has been completed. A copy of the appropriate test procedure is also enclosed. The
. " stem incorporates reactor trips on both turbine trip and loss of all main feedwater flow. To indicate the comparative effectiveness of the reactor trip upon turbine trip, the DB-1 design previously provided for automatic runback upon ICS power-demand mismatch to preclude any reactor trip resulting in opera-tion on the turbine bypass valves and main steam code safety valves. The new reactor trip system provides a direct reactor trip upon turbine trip which circumvents any runback attempt.
The interim reactor trip for loss of feedwater is generated by reverse dif fer-ential pressure across the main feedwater check valves, indicating loss of feedwater flow to both steam generators. The DB-1 design insulates the main feedwater pumps (MFP) from upstream condensate and feedwater system pert.urbations by the use of stored inventory in the full flow deaerator storage tanks. As noted in Table 4 of NU1EG-0560, " Staff Report on the Generic Assessment of Feedwater Transients in Pressurized Water Reactors Designed by the Babcock &
Wilcox Company", there are no common MFP trips utilized or required. The loss of flow to both steam generators from any cause will be sensed by the interim system and provide a reactor trip signal within 1 second.
This interim system provides reactor trip protection not available previously in the incipient stages of transients related to turbine trip and loss of main feedwater flow.
The cabinet housing the low power turbine trip bypass switch will be locked with the station shift foreman retaining the key in his key locker.

Complete analyses for potential small breaks and develop and implement operating instructions to define operator action.
Response
Analyses for potential small breaks have been provided generically by B&W in their May 7, 1979 report, " Evaluation of Transient Behavior and Small Reactor Coolant System Breaks in the 177 Fuel Assembly Plants, Volumes I & II". Addition-ally, to provide more detailed operational guidelines, a Volume III of this report was developed to relate directly to the Davis-Besse Nuclear Power Station, Unit 1, configurations and design details. Volume III was submitted on May 22, 1979 (Serial No. 506). Procedures developed from these analyses were submitted for your review on May 23, 1979 (Serial No. 509) .

All licensed reactor operators and senior reactor operators will have completed the Three Mile Island Unit No. 2 simulator training at B&W.
Response
All licensed reactor operators and senior reactor operators stationed at Davis-Besse Nuclear Power Station, Unit 1 have completed TMI-2 event simulator training.
Additionally, Toledo Edicon conducted extensive post-TMI-2 operator training previously described in Attachment A of our May 26,1979 (Serial No. 512) letter. The results of that training has been audited on-site by NRC representatives from both Nuclear Reactor Regulation and Office of Inspection and Enforcement.
Those operators who scored less than 90% on the initial evalcation examination or who were unavailable when it was administered, will be administered a new exam developed, reviewed and approved using the same guidelines as the first exam.
All of these persons must complete this exam with a minimum 90% grade before being permitted to assume license duties in Mode 1.
Prior to this second examination the Davis-Besse Training Staff will be responsi-ble for administering additional training. For those operators who were un-available for the previous exam the initial training effort as described in our letter of May 26, 1979 (Serial No. 512) would be administered. Those who did not achieve 90% or better on the first exam will be required to complete a shift reading program consisting of plant change and procedure revisions. Additionally, a four-hour review of prior training will be required followed by on-shif t operator oral examinations conducted on emergency procedures.
Training shall be provided for those procedures revised to include additional guidance as a result of NRC review by utilizing on-shift reviews of procedures and oral walk-throughs.
2239 117 June 15, 1979 Docket No. 50-346 License No. NPF-3 Serial No. 515 Item IV (1)(f)
Submit a re-evaluation of the TEco analysis of the need for automatic or admin-istrative control of steam generator level setpoints during auxiliary feedwater system operation previously submitted by TECo letter dated December 22, 1978, in light of the Three Mile Island No. 2 incident.
Response
Toledo Edison's re-evaluation of the need and desirability for a steam generator dual level setpoint was provided by our letter of May 19, 1979 (Serial No. 505).
As a result of subsequent discussions with your staff further explanation is provided here to illustrate the adequacy of this control at the Davis-Besse Nuclear Power Station, Unit 1 (DB-1).
Following reactor trip the DB-1 reactor is designed for feedwater inventory level control in its steam generators. If the reactor trip is followed by a Steam and Feedwater Rupture Control System (SFRCS) actuation, a 35-inch level control setpoint is established to provide for adequate decay heat removal without overcooling the RCS. The 35 inch level control setpoint also provides adequate RCS natural circulation if forced coolant flow is lost. This level setpoint is applicable when no incident level 2 (<-1600 psig, small break) actuation of SFAS has occurred.
Auxiliary feedwater (AFW) flow is established to one or both steam generators within 40 seconds when auxiliary feedwater is required and the peak reactor coolant system (RCS) pressures and temperatures will occur prior to 40 seconds at the time the reactor is tripped. The most severe overheating events requiring AFW are loss of main feedwater flow, main feedwater line breaks and loss of offsite power accidents. After the reactor is tripped, the RCS temperatures and pressures will go down using the steam generators as the heat sink. When AFW flow is started, the RCS rapidly cools down due to the cold AFW flow until the desired steam generator (SG) level is obtained and the SG secondary water temperature has heated up to 550 F (saturation temperature for the code safety valve setpoint of 1050 psig) .
The effect of this level control on the RCS following reactor trip is to reduce and maintain RCS temperature with normal or auxiliary feedwater consistent with the saturation pressure of the steam generators. This results in a RCS temperature of about 5500F under steady state conditions. Since level control is adequate to provide decay heat removal capability via the steam generator following reactor trip, all RCS parameters (including system pressures) are maintained within their normal pressure-temperature operating ranges. Therefore, the 35-inch level control has no adverse effect on the DB-1 FSAR accident analyses.
2239 118 June 15, 1979 Docket No. 50-346 License No. NPF-3 Serial No. 515 Item IV (1)(f) Response (continued)
In the event that forced RC flow is lost, the 35-inch level control setpoint is established by auxiliary feedwater addition to the steam generators within 40 seconds following the loss of RC pumps. The effectiveness of the 35-inch control level in promotion and maintenance of adequate natural circulation conditions in the RCS has been demonstrated in tests conducted at DB-1. These tests confirm the flow requirements for natural circulation stated in DB-1 FSAR Table 15.2.5-4 for the loss of forced reactor coolant flow accident evaluation.
Thus, the control of the AFW at 35-inches does not change previous analyses for peak temperature and pressure.
In cases such as small RCS breaks the Davis-Besse 1 AFW control system provides control of the SG level to 35-inches prior to SFAS actuation and control to 120 inches following SFAS actuation. The impact of the dual level control system on small break transients has been examined and was found acceptable.
Small break analyses performed in the Topical Report BAR-10075A, Rev. 1, and the letter report, J. H. Taylor to R. J. Fbttson, dated May 7,1979, cover a break size range of 0.01 f t.2 through 0.5 ft2 For all of these breaks, SFAS actuation occurs prior to the SG level decreasing to 120 inches. Thus, the dual level control will be set to 120 inches prior to AFW delivery and the small break analyses remain valid.
For breaks smaller than 0.01 ft2 , it is possible that the SG level control setpoint will initially be at 35-inches and then will be raised to 120 inches following the actuation of the SFAS. The interim period of control at 35 inches will have no effect on the transient. As demonstrated by the 0.01 ft2 break case, presented in section 6.2.5 of the May 7 report, the reactor coolant system will remain solid with a pressurizer bubble until the system depressurizes to 1400 psia causing flashing in the primary system. Since this is lower than the SFAS trip signal (41650 psig), the dual level control will be set to 120 inches prior to saturation in the primary system. Prior to actuation of SFAS, the SG level will be controlled to 35-inches and will maintain natural circulation. As documented in Appendix I of the reference, natural circulation tests performed at Dsvis-Besse 1 demonstrate the ability of the 35-inch level to maintain natural circulation and decay heat removal via the steam generators. Thus, the dual level control system will not adversely affect the capability of the ECCS system to control very small breaks.

Equipment No. 3.2 The RPS cabinet keys and the RPS channel bypass key must be obtained from the Shift Foreman. Verified Date ( ,j 4 PRECAUTIONS AND LIMITATIONS 4.1 For on-line testing, the key operated " CHANNEL BYPASS" switch, associated with the RPS channel being tested, shall be used to codify the respective logic to a two (2) out of three (3) code. 4.2 "0N TEST" lamp on test circuits should be DIM in the "0PERATE" position. In all other positions, the "0N TEST" la=p should be BRIGHT. All other lamp indications are DIM for NCRMAL and SRIGHT for TRIPPED or AB"0RMAL (except the la=ps on the Contain=ent Pressure Buff er Amp which are OUT for normal, ON for abnor=al) . 3 4.3 The test selector switch has a cechanical stop between the " TEST OPERATE" position and the "0PERATE" position. To cove the switch out of the " TEST OPERATE" position into the "0PERATE" position, it is necessary to push the knob and hold it while turning CCW. It is not necessary to push the knob when switching between any other positions. 4.4 Before testing any codule in the RPS, it should be energized for at least 30 minutes. 4.5 RPS location for all codules is given as follows: (loc. 1-2-3) 3 1.e. the location is cabinet number ~., row number 2, codule ( j location 3 (location is identified f::om lef t to right). 2239 177
~
3 ST 5030.02.3 4.6 RPS codule locations are posted inside the channel cabinet doors. [M 4.7 If this procedure is run at a power level < 107. full power, the testing of the Intermediate Range Channels will result in a
=ocentary SUR Rod Withdrawal Inhibit.
4.8 All bistables have two lamps on their face: " OUTPUT FEMORY" and
" OUTPUT STATE". The "CUTPUT STATE" lamp is bright when the bista-ble is in the tripped state. The " OUTPUT MEMORY" la=p is bright when the bistable is or has been in the tripped state. The following occurs when a bistable trips and cust be reset.
4.8.1 Trip Bistable (one that provides a reactor trip function)
- 1. When the input parameter reaches setpoint, the trip bistable trips. Both the " OUTPUT }EMORY" and " CUT-PUT STATE" la=ps go from dim to bright.
- 2. When the input paraceter no longer exceeds the set-point, the " OUTPUT >EMORY" and " OUTPUT STATE" lamps re=ain BRIGHI,
- 3. The trip bistable may now be reset by depressing the "0LTIPUT STATE" reset toggle. The " OUTPUT STATE" lamp will go DIM.
- 4. The "0 M PUI MEMORY" lamp is reset by depressing the "OUIPUT >IMORY" reset toggle. The "CUTPlTr MEMORY" lacp will go DIM.
4.8.2 Bistables providing protective functions other than trip-ping the Reactor Trip Podule.
- 1. When the input parameter reaches setpoint, the bista-ble trips and both the " OUTPUT !EMORY" and " OUTPUT STATE" la=ps go from DIM to ERIGHT.
- 2. When the input parameter reaches the reset setpoint, the " OUTPUT STATE" lamp will go DIM.
- 3. The " OUTPUT >EMORY" lamp is reset by depressing the OUTPUT >EMORY" reset toggle. The "OUTPLII >$MORY" la=p will go DEM.
S. PREREOUISITES 5.1 Check computer points R799 and R808 m determine which RPS Power Averager the ICS is accepting for control. The averager with the highest value will be used for ICS control. If the ICS is con-trolling frcm the averager associated by the channel being tested, notify the operator there may be a bump when the PRIti is in " TEST OPERATE". This prercquisite is not applicable if power is in the source range. Verified Date 2239 178
