q ,/ THE LIGHTING SURVEY PERFORMED IN 1983, DURING THE CONTh0L ROOM DESIGN REVIEW, INDICATED UNACCEPTABLE LIGHTING LEVELS AT BACK PANELS C5715 (10-13 FTC), C5716 (16-22 FTC), C5717 (17-20 FTC),
AND C5718 (14-30 FTC). THE MINIMUM ILLUMINATION LEVEL FOR THESE AREAS IS 20 FTC. THE PAM PANELS, C5798/99 WERE ALSO LISTED AS DISCREPANT: HOWEVER, THE MEASURED ILLUMINATION LEVELS (23-33 FTC)
AND EVALUATION IN THE PAM SPECIAL STUDY INDICATE OTHERWISE.
THE OPERATORS DESK (C5701) IS ALSO LISTED AS DISCREPANT AS THE MEASURED LEVELS RANGED FROM 39-43 FTC. THIS IS LESS THAN THE l 50 FTC MINIMUM FOR READING HANDWRITTEN MATERIAL (PENCIL) BUT i I
SATISFACTORY FOR THE 20-50 FTC REQUIREMENT FOR READING PRINTED MATERIAL. THE 1983 SURVEY L D NOT INDICATE WHETHER ALL LIGHTS WERE ON AND/OR THE CLEANLINESS OF THE LIGHTING HARDWARE.
CONTROL ROOM LIGHTING MEASUREMENTS WERE RETAKEN ON 12/18/87. RE-SULTS ARE PROVIDED IN MPR LETTER TO S. VEALE (EXT-88-OO666). IT i WAS NOTED THAT ONE STRING OF FLUORESCENT LIGHTS IS LOCATED OVER PANELS C5715-17 RATHER THAN ABOVE THE FRONT. ALSO DUCT WORK j WHICH RUNS ABOVE, AND DIRTY DIFFUSER GRATES CONTRIBUTE TO DEGRADED j LIGHTING IN THIS AREA. IT WAS ALSO NOTED THAT 2 STRINGS OF LIGHTS WERE OUT FROM PANEL C5722 TO THE RIGHT CONSOLE C5711-14.
THE MEASUREMENTS ON 12/18/07 CONFIRMED THAT LIGHTING LEVELS AT PANELS C5715 THROUGH C5718 WERE TOO LOW. LEVELS RANGED FROM 9-10 FTC AT C5715 TO 13-16 FTC AT C5718. THE ILLUMINATION
, SPECIAL STUDY CONCLUDED THAT THE LIGHTING FIXTURES IN THIS AREA s SHOULD E MOVED OR CHANGED TO FOUR-BULB FIXTURES. THE DIFFUSERS l SHOULD BE CLEANED. I IT WAS ALSO NOTED THAT THE LIGHTING LEVELS AT PANEL C5722 WERE MARGINAL (15-19 FTC). THIS IS LIKELY DUE TO THE THREE FIXTURES IN THIS AREA WHICH HAVE BURNED OUT OR MISSING BULBS. THESE FIX-TURES SHOULD BE RETUPNED TC OPERATION.
LIGHTING AT THE OPERATOR'S DESK (C5701) RANGED FROM 43-57 FTC.
OPERATORS REPORTED THAT LIGHTING AT THE DESK IS SATISFACTORY.
NO MODIFICATIONS TO THE LIGHTING IN THIS AREA ARE NECESSARY.
MODIFICATION 88-0110 WILL CORRECT THE LIGHTING LEVELS OVER PANELS C5715-C5718. '
WORK REQUESTS 88-1662 AND 88-1663 WERE ISSUED TO CLEAN THE !
DI FFUSEn": AND REPLACE THE BURNED-OUT BULBS (MWO 1-88-1511-00).

Evaluation in the Engineering special study has established that the problem is confined to the 120 V bulbs used on the switchyr.rd panel (C5723). Although some corrective steps have been taken (caution labels and proper tools), they have not been completely effective and incidents of shorting have continued. RFM 87-1252 has been issued requesting correction of the problem.
- CHANGE TO DISPOSITION / JUSTIFICATION:
FCR 87-1208 was not_ fully implemented during the 6RFO. That portion of the modification which required an outage to complete has been accomplished. The remainder of the modification vill be completed during the 7th Cycle. Ccmpletion of the modification vill continue to be tracked by the DCRDR Database.

DISPOSITION: 5 Add Reflash - If alarm vindov is in and other another subsequent con-dition for the same alarm comes in, then that alarm vindov vill begin to flash and the horn vill sound. The alarms with an "A" in this r column are recommended as candidates for the addition of reflash during the fifth refueling outage. Alarms with a "B" in this column are recommended us candidates for the addition of reflash during the sixth refueling outage.
! Local Panel Ack and Reset - An alarm comes in and an operator is sent to a local panel. At that panel he acknowledges the alarm. The alarm vindow in the control room goes out and vill come on again if another subsequent condition for that alarm comes in. Alarms with an "X* in this column are recommended for the addition of this feature during the sixth refueling outage.
CilANGE TO DISPOSITION / JUSTIFICATION: n (',) The reflash implementation was requested in RFM-0078 and the Local Ac-knowledgment was requested in RTM-0077. The original multiple input 6 review recommended the addition of reflash or local acknowledgment and reset to 42 alarms during the sixth refueling outage. An update of the original review has been performed to take into account recent alarm modifications and to prioritize the need for reflash and local panel acknowledgment / reset. Prioritization was performed to. help determine whether alternate corrective action is appropriate for some alarms, i.e. whether additional operator surveillance of some multiple input alarms should be recommended in lieu of hardware changes. The updated and reevaluated list of alarms is attached. The pri-oritization was based on the likelihood of the occurrence of multiple inputs concurrently and included consideration of available redundant components and severity of consequences. Four priority levels vere used, 1 being the highest priority, identifying those alarms that are most in need of reflash or local panel acknowledgment; priority 4 identifies those alarms where masking of subsequent inputs is least likely or where the consequences of this masking are less severe. As a result of the reevalution and prioritization, corrective action re-quiring hardware changes (reflash or local panel acknowledgment / reset) vas selected for alarms in the top three priority levels. Additional ! surveillance of the local components or local alarm panels was recom-I mended for the fourth (lovest) priority level alarms whenever these alarms are lit. To facilitate surveillance of multiple input p' annunciators that do not have reflash, additional information was added
' v to the annunciator tiles. A letter "M" is engraved in the upper left corner for multiple input alarms and a letter "R" is engraved in t~e n lover left corner for alarm vindows that have reflash.

Simon, Senior Performance Engineering Technologist % Eusli5t MOD 88-0208, Alarm Vindov 6-5-A NE0-89-00761 Vindov 6-5-A, Shaft Vibration High, was listed as requiring reflash. Upon i investigation of the best method to provide reflash, it was determined that local reset at the RCP monitoring and diagnostic cabinet vill clear the vindow (even if an alarm condition still exists in the field) and allow reflash on subsequent alarms. As the Control Room cabinet where local reset is performed has a display and a printer listing all alarms as they come in, the present design is considered adequate to inform the operators or any alarm. condition on any RCP vibration. It is desired that the operators respond to an alarm by going to the cabinet and performing local reset to allow reflash. Reflash for vindov 6-5-A should be deleted from the scope of MOD 88-0208. A project to upgrade the RCP monitoring and diagnostic system is being pursued by Systems Engineering. It is suggested that this upgrade include a software change to provide reflash. The objective should be to have the annunciator vindow stay on when reset on the Control Room panel, even after local cabinet rest and provide reflash for subsequent alarms. This vould enhance the present design that . gives a clear board in the Control Room (after local cabinet reset), even though an alarm condition exists in the field. As this is primarily a difference from normal alarm conventions and a turnover concern from an operational perspective, it is suggested that Operations include a once a shift check of the local monitoring and diagnostic cabinet as part of their Control Room readings. This check could be discontinued if and when a softvare change as described above is made. LPS/mjb cc R. Androsik D. Evans C. Jaffee J. Kasper D. Ricci A. Zarechnak (MPR) Chron File PE File

ALL MULTIPLE INPUT ALARMS HAVE BEEN IDENTIFIED AND REVIEWED AGAINST THE CRITERIA IN NP-3448. REVIEW OF THE DAVIS-BESSE MULTIPLE INPUT ALARMS IS SUMMARIZED IN MPR LETTER DATED 11-6, 1987 (EXT-87-09255). ATTACHMENT 2 TO THAT LFTTER IDENTIFIES 14 CRITICAL ALARMS FOR WHICH REFLASH CAPABILITY IS RECOMMENDED FOR FIFTH REFUELING OUTAGE IMPLE-MENTATION. ATTACHMENT 3 TO THAT LETTER IDENTIFIES AN ADDITIONAL 42 MULTIPLE INPUT ALARMS FOR WHICH REFLASH, LOCAL PANEL ALARM AND RESET, OR COMPUTER POINT ADDITION IS RECOMMENDED FOR SIXTH REFUELING OUTAGE IMPLEMENTATION. ATTACHMENT 4 TO THAT LETTER LISTS THOSE MULTIPLE IN-PUT ALARMS FOR WHICH NO ACTION IS NEEDED. ATTACHMENT 5 TO THAT LET-TER SUMMARIZES THE RECOMMENDATIONS FOR ALL 207 MULTIPLE INPUT ALARMS, RELATED HEDS ARE 31024, 31025, 31026, 31027 AND 31028. THE ALARMS WHICH WERE LISTED IN THOSE RELATED HEDS WERE REVIEWED AND ARE IN-CLUDED IN THIS HED. THE ALARMS WHICH WERE REVIEWED ARE TABULATED IN THE ATTACHED COMPONENT LISTING. RECOMMENDED ACTIONS ARE SUMMARIZED BELOW WITH THE FOLLOWING DEFINITIONS: ( 1. ADD REFLASH - IF ALARM WINDOW IS IN AND ANOTHER SUBSEOUENT CON-(_)) DITION FOR THE SAME ALARM COMES IN, THEN THAT ALARM WINDOW WILL BEP'N TO FLASH AND THE HORN WILL SOUND. THE ALARMS WITH AN "A" IN .415 COLUMN ARE RECOMMENDED AS CANDIDATES FOR THE ADDITION OF REFLASH DURING THE FIFTH REFifD ING OUTAGE. ALARMS WITH A "B" IN THIS COLUMN ARE RECOMMENDED F CANDIDATES FOR THE ADDITION OF REFLASH DURING THE SIXTH REFUELING OUTAGE.
- 2. CORRECT PROCEDURE - DENOTES A PROCEDURAL PROBLEM WHICH WAS NOTED DURING THE REVIEW PROCESS.
- 3. LOCAL PANEL ACK & RESET - AN ALARM COMES IN AND AN OPERATOR IS SENT TO A LOCAL PANEL. AT THAT PANEL HE ACKNOWLEDGES THE ALARM.
THE ALARM WINDOW IN THE CONTROL ROOM GOES OUT AND WILL COME ON AGAIN IF ANOTHER SUBSEQUENT CONDITION FOR THAT ALARM COMES IN. ALARMS WITH AN "X" IN THIS COLUMN ARE RECOMMENDED FOR THE ADD-ITION OF THIS FEATURE DURING THE SIXTH REFUELING OUTAGE.
- 4. ADDITIONAL COMPUTER POINTS ARE RECOMMENDED FOR ALARM 1-6-7 DURING THE SIXTH REFUELING OUTAGE.

. DAVIS-BESSE HUMAN ENGINEERING DISCREPANCY REPORT ADDENDUM
-HED NO: 4.1.007-Controls with strict sequential activation are not interlocked. .
DISPOSITION / JUSTIFICATION - The controls special study group established that no corrective action is needed for the CVRT inlet val.cs or the RC letdown demineralizer valves since~ training should be adequate and the consequences of-error-are not serious. However, the operation of the MU pump oil pumps is a serious problem which is to be corrected such that false indications are not-received. RFA 88-0682 has been written to investigate this problem. On the control rod drive panel (C5706), a permanent warning label has been added to the prime interlock control. CHANGE TO DISPOSITION / JUSTIFICATION: MOD 88-0145 has been implemented to correct the MU pump oil pump problem. This HED item is closed.

-2. MAKEUP PUMP OIL PUMPS A PROBLEM WAS IDENTIFIED WITH THE MAKEUP PUMP LUBE OIL PUMP INTERLOCKS. IF THE STARTING AND STOPPING FUNCTIONS ARE NOT OPERATED IN THE PROPER SEQUENCE, THE OPERATOR LOSES CONTROL-OF THE OIL PUMPS AND A FALSE INDICATION WILL RESULT.
WHEN THIS OCCURS, A BREAKER MUST BE LOCALLY OPENED AND RESET TO RETURN CONTROL.OF THE OIL PUMPS TO THE CONTROL ROOM. l

'The Controls Special Study concluded-that-engineering vork to change the valve light logic so that both lights are on when the valve is; 3 stroking should be initiated. If not all valves can be changed at'one time, those valves which operate differently vill be labeled and included in operator training. This-vill be implemented by MOD 88-0120. ;
CHANGE TO DISPOSITION / JUSTIFICATION: The throttling valves present the greatest human factor deficiency due. to lack of feedback while the valve being in mid-stroke position for an-extended period of time. The ability to modify the logic of all valves to provide dual light indication during valve transit is severely limited by1 resources and thus MOD 88-0120 was voided. . Throttling.. valves are: labeled to identify then as throttling valves'and willsbe~ { )' provided with dual light indication while in mid-stroke position. Eleven valves have been provided with dual light indication by MOD'

88-0214 during the 6th Refueling Outage. t MOD 88-0214 did not include 5 throttling valves within the scope of the' MOD. AS-196 A&B, AS-198 A&B, and GS-2386 are employed mainly when the plant is in a shutdown status. MOD 89-0096 was written to provide these valves with dual light indications during transit. It was the decision of the Action Planning Committee held on August 1, 1989, to defer the implementation of the MOD until the 7th Cycle. The circumstances which dictated the decision by the Action Planning Committee are as follows:
- a. Late receipt of'the Request for Modification (RFM)
- b. 6RF0 retources are fully committed to the MODS currently scheduled for the 6RFO.
- c. Design Engineering was directed to give MOD 89-0096 a high priority, but vill have a lover priority than those modifications currently scheduled for the 6RF0.
- d. Implementation of MOD 89-0096, upon completion of the design phase, would be scheduled to coincide with the respective valve PM's cycle.
V) r
i l I e. MOD 89-0096 may be implemented prior to the 7RF0, but not later r e
'T than the 7th Refueling Outage. -(s_ f Rational for non-inclusion in 6RFO:
MOD 89-0096 vas vritten in order to maintain the convention that. motor operated valves are provided with dual light indication when in mid-stroke position. This convention vill provide the operators with a positive feedback indication for those valves that may be in mid-stroke positions for e:: tended periods of time. The current design is to have both the red and green lights not lit during the valve's mid-stroke transit. MOD 88-0214 is scheduled to be implemented during the 6RF0 and vill provide the indication for throttle valves. In the course of the review of the MOD 88-0214, design package, June 21, 1989, it was 61scovered that 5 throttle valves were inadvertently omitted from the MOD. A review of the drawing of all motor operated valves without a seal-in was conducted to ensure that no ' other throttling valves vere omitted. Upon completion of the drawing review, it was confirmed that the 5 throttling valves identified were the only ones not included in MOD 88-0214. A new modification, MOD. ! 89-0096, was written on July 24, 1989, to provide dual light indication ! for these 5 valves. Due to the des'ign schedule for modification design preparation and the impact on the outage workload, it was determined by Toledo Edison's management that MOD 89-0096 vould not be scheduled for the 6RF0 implementation. The basis for this decision is that these 5 valves are not critical to plant operation and they can be scheduled 7-l i for~ cycle 7,'i.e., during operations following startup from the 6RFO.
"' If the 5 throttling valves identified in H0D 89-0096 are not provided with dual light indication in the 6RF0, they vill be labeled to identify them ar operating differently, i

DISPOSITION: The Displays Special Study Group determined that the range of the l condenser pressure recorder (PR 5330/531) is too narrow (0 to 10 inches of HG.) and should be expanded to greater.than 17 inches of HG. to cover alarms and turbine trip limits. MOD 88-0119 vill implement this change. It was also determined that local level indication is needed and should be provided for the Emergency Diesel Generator Fuel Oil Tanks. MOD 87-1208 vill implement.this change. CHANGE TO DISPOSITION / JUSTIFICATION: PR 530/541 vill be replaced under Simple Configuration Change (SCC) 88-1192. It has been determined by operations Management that the change to the g>. Condenser Pressure Recorder is not desired as loss of resolution could occur during normal operations. The RFA/ SCC 88-1192 vill be voided. Ref. L. P. Simon, DCRDR Project Leader Memorandum NEO-89-00720 of June 28, 1989. PCR 89-4500 has been incorporated in Abnormal Procedure DB-0P-02518 vhich removes the requirement for specific operator action at 12.5" Hga. MOD 87-1208 was not fully implemented during the 6RFO. Since local level indication is considered to be an operational enhancement and not critical to plant operations, that portion of the MOD which did not require an outage to complete, has been deferred to the 7th Cycle. Completion of MOD vill be tracked by the DCRDR Database. O L_

$UBJtcT Condenser Pressure Recorder PR530/PR541 NEO-89-00720 HED 5.1.004 was dispositioned by the Displays Special Study group that additional range of condenser pressure indication is needed. MOD 88-0119 was written to accomplish this. Later RFA 88-1192 vas written to perform the change under a Simple Configuration Change (SCC) and void MOD 88-0119.
.It has now been determined by Operations Management that no change to the condenser pressure recorder is cost benefit justified.
The following factors vere considered in making this determination:
- 1. If the recorder scale is changed from 0-10" to 0-20" HgA some loss of resolution hat the lov end (<5" HgA) would occur. This is not desired as this is the normal operating band with the unit on line.
- 2. Automatic actions that occur above full scale [MFPT trips at 12.5" and TBVs interlock to AVVs at 17"] vill occur from separate pressure switches. The MFPTs tripping at 12.5" vill cause a SFRCS actuation, closing MSIVs and render the TBV interlock at 17" unneeded. (A rare case with the MDFP on could still cause the TBV 17" interlock to be of some value). The MFPTs condenser pressure trip is actuated by two separate pressure switches for each MFPT. This redundancy makes operation action at 12.5" HgA highly unnecessary. Rupture disk on the NFPT exhaust and low pressure turbine hoods provide additional engineering backup.
- 3. The HED identified a concern that without a scale range covering automatic actions the operators may take action that vould cause unnecessary plant transients. (i.e., if the CTRM indication pegs out at
,10" HgA, the operation may or should trip the MFPTs) As the NFPTs have redundant low vacuum trips and their is little chance of having a transient stabilize vacuum between 10" and 12.5" HgA this concern is considered not valid. A PCR has been written to change Abnormal Procedure DB-0P-02518, to remove the requirement for specific operator action at 12.5" HgA (or require local indication of pressure to be relayed to the CTRM).

SCALE SPAN UNEXPECTED l l DISCUSSION OF PROBLEM: The HED identifies twenty-four (24) components on eight (8) panels as having meter scales that do not span the expected range of operational parameters. The HED also identifies "ED Fuel Oil" as having this problem but no panel is identified. Further, the HED does not identify the expected range of I operational parameters for each meter listed, i.e., why the scale span is
" unexpected" is not indicated. This HED (51004) and HED 51005 address the I specific problems identified in general by another HED (98010).
In general, the HED is based on the NUREG C700 Guideline requirement for scale ranges (6.5.1.2.d) which states:
" Scale *, should be selected to:
(1) Span the expected range of operational parameters, or (2) Employ appropriate scale ranging techniques, or (3) Be supported by auxiliary wide range instruments." Specifically, the HED was generated for part (1) of this guideline paragraph. Note that the NUREG 0700 Guideline requires either (1), (2) or The HED does not specify whether the components listed also failTne(3)requirements above. of both (2) and (3) above. The Task Analysis dated hay 21, 1987, did not identify any problems for the components listed in tnis HED concerning the. meter scales spanning the expected range of an operational parameter. Consequently, the discrepancies identified by this HED have not been confirmed by the Task Analysis. This HED is based on the responses to operator interviews. Four of thirteen operators responoed to the . aestion "Do operational parameters of displayed values on meter scales span the range you would expect?" with a "NO." These operators listed some components; however, in only a few instances were there any indication of the actual problem. The following were listed with no indication of the specific problem. They were discussed by the Displays Special Study Group in a meeting on February 3,1988. No significant problem with the spans of these displays were identified.

The HED lists four RC pump seal injection flow meters. The operator interview response was " SEAL INJ FILTER." The handwritten version of the HED identifies the problem is with " SEAL INJ FLOW." It was confirmed by the Displays Special Study Group that neither the components listed by the HED nor the seal injec-tion filter have problems with scale span. : Based on the handwritten version of the HED and the operator interview responses, the Condensate Comoined Flow meter (FI 578) is identified as having i g " range too small" with a note indicating that the scale readings need to be kept "below 8." However, the current scale range for FI 578 is 0 to 10 mpph. t]
\
(A problem concerning the progression of scale graduations on FI 578 is adde:ssed by HED 51028.) The handwritten version of the HED and the operator interview responses indicates a problem with the " Core Flood Tank" meters (LI CF3A1, A2, B1 j and B2) in that these meters display level in feet while the Tech. Spec. is 'n gallons. This is a separate issue and is covered by another HED (0A028). The l HED cites the core flood tank pressure as well as level. The meters are dual ; meters with pressure and level on each of four meters. The pressure scale is ! r,ot involved in this problem and should not have been listed. The HED lists "PI 569 CNDS PUMP n!3CH HEADER PRESS." The operator interview responses and the handwritten version of the HED identify "CNDSR PRESS." It

was determined by the Displays Special Study Group that the proper component I was not listed by the HED. IThere are proolems witn the range of the condenser pressure, specifically. The operators . read condenser pressure f rom a dual trace recorder (PR 530/541) on the right console. It has a span from 0 to 10 inches r',Hg-(absolute). This range covers the alarms and trip of the main turbin - However, the main feed pumps will operate to a pressure of 12.5 inches and the TBVs to 17 inches of Hg. Ir abnormal procedure AB 1203.25 tne
- operator is given that guidance; however, there is no display in the control l room which can provide him those pressure values. (The computer point P447 has the same range as the recorder.) It was concluded by the Displays Special Study Group that additional range of condenser pressure indication is needed

^ in the control room. It was noted that this is not a safaty problem of l itself; however, it may cause the operator to take action to cause unnecessary i plant transients. l l
The operator responses also cited two other items:
"All on Post Accident Monitoring panel" and
* " Electrical Panel" There are other HEDs on these components and in the case of the PAM panel l extensive modifications are planned. The HED has properly ignored these responses.
The original handwritten version of this HED and one operator's response indicates the problem with the "ED FUEL O!L" is, in fact, the lack of a display of the emergency fuel oil level in the control room. One of the thirteen operators cited this item and stated that operators have to sound the-tank locally. This is a completely different problem from the guideline referenced. It was discussed by the Displays Special Study Group in a muting tq on February 3, 1988. The emergency oil tanks (week tanks) are alarmed at a
.g level which is above the Tech. Spec. limits. However, since there is no level indication (even locally), the operators must sound the tank repeatedly after an alarm is received to be sure that the Tech. Spec, limit is not reached before the tank is filled. In addition to requiring the operator's time, the tank must be opened each time the level is determined which increases the p"ential for contamination of the oil. The Displays Special Study G.oup con:luded level indication should be provided. .
PROPOSED O!SPOSITION AND JUST!FICATION: The Task Analysis dated May 21, 1987 did not identify any of the components listed as having meter scEles that do not span the expected range of oper-ational parameters. The Displays Special Study concluded that the components identified by the HED do not constitute an operational problem for the operators excert the range of the condenser pressure instrument is too small g and a display of emergency oil tank level is neeoed. l On February 4, 1988, the DCRDR Review Team concurred with this disposition. CORRECTIONS AND MODIFICAT!0NS TO HED: Add HEDs 51005 and 98010 as related HEDs. p 8

' Condenser Pressure Recorder PR530/PR541 NEO-89-00720 HED 5.1.004 vas dispositioned by the Displays Special Study group that additional range of condenser pressure indication is needed. H0D 88-0119 was written to accomplish this. Later RFA 88-1192 vas written to perform the change under a Simple Configuration Change (SCC) and void H0D 88-0119.
It has nov been determined by Operations Management that no change to the condenser pressure recorder is cost benefit justified. The following factors were considered in making this determination: 1. If the recorder scale is changed from 0-10" to 0-20" HgA some loss of s resolution hat the lov end (<5" HgA) would occur. This is not desired as
,f t
this is the normal operating band with :he unit on line. 2. Automatic actions that occur above full scale (HFPT trips at 12.5" and TBVs switches. interlock to AVVs at 17"] will occur from separate pressure The HFPTs tripping at 12.5" vill cause a SFRCS actuation, closing MSIVs and render the TBV interlock at 17" unneeded. (A rare case with the HDFP on could still cause the TBV 17" interlock to be of some value).. The HFPTs condenser pressure trip is actuated by two separate pressure svitches for-each HFPT. This redundancy makes operation action at 12.5" HgA highly unnecessary. Rupture disk on the HFPT exhaust and lov pressure turbine hoods provide additional engineering backup. 3. The HED identified a concern that without a scale range covering automatic actions the operators may take action that would cause unaccessary plant transients. (i.e., if the CTRH indication pegs out at 10" HgA, the operation may or should trip the HFPTs) As the HFPTs have redundant low vacuum trips and their is little chance of having a transient stabilize vacuum between 10" and 12.5" HgA this concern is considered not valid. A PCR has been written to change Abnormal Procedure DB-0P-02518, to remove the requirement for specific operator action at 12.5" HgA (or require local indication of pressure to be relayed to the CTRh).

-TITLE:
Scale graduations do not progress by 1,2,5 or 10s. DISPOSITION:- It was concluded that the progression of scale graduations on flov meters FI RCIA and FI RC1B on panel C5710 and FI 578 on'C5714 are a prob 1cm for_the operators. The scales on these meters vill be replaced by scales incremented by 1,2,5,10 or multiples of 10 by MOD 88-0123 and 88-0124. CilANGE TO DISPOSITION / JUSTIFICATION: The scale replacement on FI 578 (panel C5714) vill be accomplished by Simple _ Configuration Change (SCC) 88-1196. SCC 88-1196 was not-implemented in the 6RF0 and is scheduled for the 7th RF0. The change to the condensate-flow meter scale is an operational-enhancement and not critical to plant operations. The scale is readable but should be improved.- The scale replacement on FI RCIA and FI RC1B (panel C5710) has been
~( implemented by SCC 88-1195.

TITLE-Zone Marking Not Distinctive on Some Meters and Most Meters Do Not Contain Zone Marking DISPOSITION: _
)
The Display Special Study Group concluded that for those displays designated by operations, zone marking should be sdoed to meter scales as follows: 1
- Technical Specificati( n limits will be indicated by a red mark, e Alarm limits will be 'ndicated by a yellow mark. )
l
- Some selected meters will have a green normal operating band.
I The MWO l 88-1721-00 <eries has been generated to implement this work, i CH ANGE TO DISPOSITION /JUSTfFICATION: On January 18,1990, a meet ng with L. P. Simon of Performance Engineering, (\ Mark B. Bezella of Operatiot:s and Douglas P. Ricci of Operations discussed HED 5.1.030 and the associated attempts at marking the various instruments. It was concicped that the resolution proposed in HED 5.1.030 was not practical in the Davis Besse Control Room and it was agreed that implementation of the disposition would introduce more problems that it would correct. See attached memorandum from L. P. Simon to file.
- HED 5.1.030 will be close without implementation of the disposition.

The marking, using the thinner tape, was not sufficiently visible and the vider tape costured the meter scales. Based on an evaluation by several operators, the me.rking of the various

- 2. Displays Special Study The Displays Special Study Group has examined each GE Type small edgewise meter and concluded that pointer widths are not so narrow that the meters present a burden for the operators. Additionally, HED 51011 listed " Bailey Recorders" and " Meters" as having pointers which are too small. 'Ihe Bailey Recorders in the Control Room are being replaced in both the SRFO and 6RFO by FCR 83-0164 No problems have been identified with the pointers. The " Meters" entry in HED 51011 alludes to all Control Room Meters. Not only those listed in HSDs 51011 and 51033. No other discrepant meters were identified.
CHANGE TO DISPOSITION / JUSTIFICATION:
- 1. Bailey Recorders continue to remain operational. These recorders will replaced when spare parts are no longer available to effect repairs.

HED N0s 9.2.002 TITLE: Related controls not co-located. DISPOSITION: The Controls Special Study concluded that the service water valve controls HIS 2927 and HIS 2928 should be moved so that they can be grouped with the other Control Room Emergency Ventilation controls. MOD 88-0093 vill implement this change. CHANGE TO' DISPOSITION / JUSTIFICATION: Reference NES 88-00674 of August 10, 1988, from J. K. Vood, Systems Engineering Director to P. C. Hildebrandt, General Encineering Director. Systems Engineering determined that the modification vould be difficult to implement due to space limitation. Since the benefits gained are minimal, the modification was recommended to be voided. A copy of the referenced memorandum is attached. Labels have been added to panel C5720 to identify the relationship between HIS 2927 and HIS 2928 and the EVS fans to compensate for not relocating these : switches. 1,-) , v i i i i a

RFM 88-0093 Relocation of HIS-2927 and HIS-2928 RFM 88-0093 is a Request for Modification to relocate.5I5-2927 and HIS-2928 which are for Service Vater Valves SV2927 and SV2928 respectively. The proposed relocation modification is a result of a Human Factors Study. The Service Water Valves supply water to the Control Room EVS (CREVS) water-cooled condensers. The modification scope is to move these handsvitches from the present location on C5720 to a new location by the Control Room EVS start handsvitches HIS-5261 and RIS-5262. Presently the Service Vater handsvitches are only about three feet away from the Control Room EVS handsvitches. Systems Engineering was asked to provide a scope of the modification to the estimating group. Upon a field valkdown, the Systems Engineer ascertained that the modification vould be nearly impossible. In the rear of the main control board panel C5720, by the CREVS handsvitches chere is no available area to mount the handsvitches. Below the CREVS handsvatches are various terminal blocks. To each side and above are other i handsvitches. Therefore, in order to relocate the handsvitches, other svitches
- and termint.1 blocks vould require modification or rework. Numerous cables vould Q
U have to be determinated and reterminated. The scope of the proposed modification is greater than a relocation of just two handsvitches. During the 5th Refueling Outage, new permanent information labels have been ', installed by the Service Vater and CREVS handsvitches identifying the interf ace j between the two systems. The proposed modification has been discussed with various Reactor Operators and Shift Supervisors who all felt the modification j vas unnecessary. They are vell aware of the Service Water interface with the Control Room EVS. Due to the cost involved relocating these handsvitches, and since the benefits gained are minimal, I recommend voiding the proposed modification. W JKV/ KG/VTP/bec l-cc: P. Gaffney L. Stor:: 4

SUBJECT:
RELATED CONTROLS NOT CO-LOCATED O!SCUSSION OF PROBLEM: This HED identifies emergency condenser unit service water outlet valve controls (HIS 2927 and HIS 2928) on panel C5720 and a " Control Emergency Condensate Switen" on panel C5730 as functionally related con:rols that are not co-located. However, based on the original handwritten HED, the " Control Emergency Condensate Switch" on PanclC5730 is incorrect and should be the Control Room Emergency ventilation System controls on Panel C5720. The WE0 does not describe the functional relationship of the controls; however, PilDs ano system operating procedures indicate that the service water valves controlled by HIS 2927 e.no HIS 2928 are only used to provide water cooling to tne Control Room Emergency ventilation condenser units. It should be noted s that these service water valve controls are located with other service water valve controls on Panel C5720. ' g The HED was discussed in a meeting of the Controls Special Study Grouc n i, Novemoer 12, 1987 In :nis meeting the following information was presented: Operation of tne Control Room Emergency Ventilation Fan Con: ols (HIS 5251) and HIS 5262) also enanges :ne position of the resoective! service water valves. l
- l Although the service water valves are clearly groupec witn : ner i service water controls, they are functionally more closely aela ed to tne control room emergency ventilation. It would simplify enecking tne proper operation of tne control room emergency ventilation if they were grouced witn the other ventilation contaois.
It is necessary for the operators to use both the f an control 4nd the service water valves to estaolisn wnetner tne air-coolec condensing unit for the ventilation system is in use. The Special Study Group concluded that it would be desiracle to move '.re service water valves so that they are adjacent to the related fan cone els. O

Brightness Discrimination Hard to'Make DISPOSITION: 1 ti.ir-HED also cites the SFAS Cabinet Data Lights. These are not in the main part of the control room, but do constitute a significant operator burden. -These data lights vill be corrected by MOD 87-1330. CHANGE T0 DISPOSITION / JUSTIFICATION: The SFAS Cabinet Data Lights problem is related to the SFAS Cabinet indication and does not refer to the i.octrol Room indications. These lights _are not normally used or vievet by the operators during emergency operations. The problem with the ambiguous SFAS data lights is primarily a concern during surveillance testing and shift checks of the cabinets. The main concern is that misinterpretation of the lights could result in an unwanted actuation of SFAS equipment during surveillance testing, or
,s an equipment problem could go undetected, when a % trip is present, during normal operations.
{ )_ l The design for MOD 87-1330 was not completed in time for 6RF0 implemen-tation and was under review to determine the need and cost benefit.-Since l the modification is considered to be an'operationel enhancement and not I critical to plant operations, this MOD is now scheduled for implementation in 7RFO. 1 l a l' l'_ l I t O l l-

i ~' f- ~ ~ HED NO: 9.2.029 TITLE: Valves open/close lights can be misleading if on or both bulbs are burned'out (Also see HED 4.1.020 Addendum). DISPOSITION: The Controls-and Displays Special Studies concluded that all valves position indicator light logic should be changed so that the lights are ; on when the valve is in a mid-position (MOD 88-0120). CHANGE TO DISPOSITION / JUSTIFICATION: The throttling valves vill be.provided with dual light indication vhile in mid-position under MOD 88-0214 and MOD 88-0120 was voided.- The ' throttling valves present the greatest human factor deficiency due to lack of feedback while the valve being in-mid-stroke position for an. extended period of time. The ability to modify the logic of all valves to provide dual light indication during valve transit is severely limited by resources and thus MOD 88-0120 was voided. Throttling valves are 1abeled to identify them as throttling valves and vill be
~
provided with dual light indication while in mid-stroke position..
.I h. Eleven valves have been provided with dual light indication by MOD \ l' 88-0214 during the 6th Refueling Outage.
M0_D,88-0214 did not include 5 throttling valves within the scope of the MOD. AS-196 A&B, AS-198 A&B, and GS-2386 are employed mainly when the plant is in a shutdown status. MOD 89-0096 was written to provide these valves with dual light indications during transit. It was the decision of the Action Planning Committee. held on August 1, 1989, to defer the implementation of the MOD until the 7th Cycle. The circumstances which dictated the decision by the Action Planning Committee are as follows:
- a. Late receipt of the Request for Modification (RFM)
- b. 6RF0 resources are fully committed to the MODS currently scheduled for the 6RF0.
- c. Design Engineering was dire.cted to give MOD 89-0096 a high priority, but will have a lover priority than those modifications ,
currently scheduled for the 6RF0.
- d. Implementation of MOD 89-0096, upon completion of the design phase, would le scheduled to coincida with the respective valve PM's cycle.
,- e. MOD 8c-0096 may be implemented prior to the 7RF0, but not later l, ,)3 than the 7th Refueling Outage.
L
- e. MOD 89-0096 may be implemented prior to the 7RF0, but.not later j
^
- 3. than the 7th Refueling Outage. -i
-i ~'
) '
Rational for non-inclusion in 6RF0:
' MOD 89-0096 was:vritten.in order to maintain the convention that motor operated valves are provided with dual light indication when in mid- .
stroke position. This convention vill provide the operators with a positive feedback indication for those valves that may be in mid-stroke positions'for extended periods of time. The current design is to have both-the red and green lights not lit'during the valve's mid-stroke transit. MOD 88-0214 is scheduled to be implemented during the 6RF0 and vill provide the indication for throttle valves. In the course of the review of the MOD 88-0214, design package,-
~ June 21, 1989, it was discovered that 5 throttle valves were inadvertently omitted from the MOD. A review of the drawing of all motor operated valves without a seal-in was conducted to ensure that no other throttling valves were omitted. Upon completion of the drawing ,
review, it was confirmed that-the 5 throttling valves identified. vere the only ones not included in MOD 88-0214. A new modification, MOD 89-0096,~vas written on July 24, 1989, to provide dual light indication for these 5 valves. Due to the design schedule for modification. design preparation and the impact on the outage workload, it was determined by: Toledo Edison's management.that MOD 89-0096 vould not be scheduled for the 6RF0 implementation. The basis for this decision is that these 5 valves are not critical to plant operation and they can be scheduled for cycle 7, i.e., during operations following startup from the 6RF0. (' /) If the_5 throttling valves identified in MOD 89-0096 are not provided with dual light indication in the 6RF0, they vill be labeled to-identify them as operating differently. l . i I <~ ! L)s.

DAVIS-BESSE HUMAN ENGINEERING DISCREPANCY REPORT ADDENDUM () m HED NO: 9.2.107 TITLE: Inadequate Information - Emergency Diesel Generator Information QLSPOSITION: This HED states that indication of diesel generator power or VARS is needed in ! the control room. However, power indicaters JI 6221 and JI 6231 are located on panel C5715 in the control room. Funhermore, VARS are required only when ; manually loading the diesel. This operation is done locally, not from the control l room. Lack of either indication was not cited as a problem during emergency operations in the verification summary of the DCRDR Task Analysis dated May 21,1987. Therefore, the Displays Special Study Group concluded that the information available in the control room is adequate for monitoring operation of the diesel generator and performing the needed control room acuen::. An indication of VARS is not needed in the control room. Comoonent Identification: EDG Indication GIANGE TO DISPOSITION / JUSTIFICATION: Engineering Assurance Program review of the DCRDR Project recommended that additional information be incorporated in HED 9.2.107 to justify why EDG instrumente:ted is adequate.

As stated in HED 9.2.107, the DCRDR Review Team di ! review the EDG controls and indications and determined that they am adquate. The Special Study Teams met in the Control Room Mockup Room. The team consisted of experienced licensed operators who were familiar with the control room and EOP's and EDG operation. The updated task analysis done in May 1987 was performed by a Human Factors expert who also had several yeam B&W plant operating experience and was assisted by licensed Davis Besse Operators. In addition to the statement in HED 9.2.107, synchronization is performed locally. Control Room operations requires less instrumentation. Control Room Annunciators exist to warn of abnormal conditions. The localindication*hsted in the component identification is not needed in the control room for several different reasons. Starting air pressure covered by control room annunciators, lube oil press - crankcase pressum - jacket water temperature are all related to EDG trips that are auto bypassed under emergency operations and covered by control room annunciators in normal operation. Normal operations requins an operator at the EDG. Voltage regulator droop and engine govenor droop mode switches am used locally for manual operation of the EDGs. Auto starts and loading automatically place voltage and engine control in the proper mode. Page: 32

THIS HED STATES THAT INDICATION OF DIESEL GENERATOR POWER OR VARS IS NEEDED IN THE CONTROL ROOM. HOWEVER, POWER INDICATORS J1 6221 AND JI 6231 ARE LOCATED ON PANEL C5715 IN THE CONTROL ROOM. FURTHER-MORE, VARS ARE REQUIRED ONLY WHEN MANUALLY LOADING THE DIESEL. THIS OPERATION IS DONE LOCALLY, NOT FROM THE CONTROL ROOM. LACK OF EITHER INDICATION WAS NOT CITED AS A PROBLEM DURING EMERGENCY OPERATIONS IN THE VERIFICATION
SUMMARY
OF THE DCRDR TASK ANALYSIS DATED MAY 21, 1987. THEREFORE, THE DISPLAYS SPECIAL STUDY GROUP CONCLUDED THAT THE INFORMATION AVAILABLE IN THE CONTROL ROOM IS ADEQUATE FOR MONITOR-ING OPERATION DF THE DIESEL GENERATORS AND PERFORMING THE NEEDED CONTROL ROOM ACTIONS. AN INDICATION OF VARS IS NOT NEEDED IN THE CONTROL ROOM. LATED MODS: FINAL DISPOSITION APPR: L. SIMCW /0/ DATE: 06/30/88

' N.- EED NO: 9.2.111 , TITLE' Inadequate information - Component Cooling Vater (CCV) System Indication l DISPOSITION: , The addition of CCW Flov and Discharge Pressure indicators vould . neither relieve the need for the operator to confirm proper. system line-up nor the need to monitor individual components. Operation does concur, however, with the installation of a temperature indicator on the outlet of #3 CCV HX (FCR 81-0225). j CHANGE 1s DISPOSITION / JUSTIFICATION ' The installation of a temperature indicator on the outlet of #3 CCV FDC was evaluated by the Vork Scope Committee and determined to not be justified. FCR 81-0225 vill be voided. The addition of #3 CCV HX i
' Temperature vas_a desire 6 operator cenvenience for normal operations ,
and is not needed to verify proper emergency operation of the CCV _f s_ system. The cost of adding an indicator for normal operation was , (') determined to be excessive for the benefit gained. Operators assign 93 CCV HX Temperature to a trend pen recorder when #3 CCW HX is in use - and the recording is adequate for normal operations. , r O
