RATING: 1.
FINDING: ;
Too many people in the control. room causes overcrowdedness and noise distractions.
RESPONSE
The size of the ANO control room contributes to the potential
[A ') for overcrowding. Due to this potential, a procedure for clearing unnecessary personnel from the control room is in use. This procedure gives the shift supervisor the authority and control of access to the control room to eliminate overcrowding. This procedure is not usually invoked during routine plant operation, but it can be at the shift supervisor's option. As a corrective measure, a reminder about the use of the existing procedure has been added to the operator's requalification training to help assure that use of the access procedure will be invoked when necessary.

Multipoint alarms require the control room operator to go to a given plant location (or local panel) for specific information.
RESPONSE
'I I Most of the multipoint alarms that require the operator to go
\/ to a given plant location (or local panel) do not cause l operational problems since they allow adequate time for l auxiliary operator action and subsequent control room operator
! action as required. Furthermore, inclucion of many of these multipoint alarms in the control room would aggravate the space l problem and/or unnecessarily complicate the computer printout
! of alarms. However, the multipoint alarms for the following do require evaluation for possible design changes since a time factor can be significant in certain cases for these clarms:
inverter lY13, lY23, 1Yll, lY22 trouble: Diesel Gen IDG1 and IDG2 trouble; and instrument air compressor trouble. These i multipoint alarms are being evaluated for a design change to

Nss' CORRECTIVE ACTIONS HED NO.: CK:5-1.001 GUIDE NO.: 5.1.lc RATING: 1 FINDING:
When panel instruments fail or become inoperative, the failure is not apparent to the operators. Some fail midscale.
RESPONSE
[x'
) The concern about the midscale failure mode due to instrument power loss (i.e., NNI-X or NNI-Y) has already been addressed by the addition of power supply indicating lights, annunciators, and an operating procedure. Upon loss of a power supply that could result in the midscale failure of instruments, an alarm occurs that directs the operator's attention to a set of power supply indicating lights. The operator then uses the operating procedure for loss of NNI-X or NNI-Y instrument power supply which identifies the instruments impacted by the power loss.
This resolution of the midscale failure instruments was imple-mented prior to the CRDR program as part of AP&L's on-going commitment to the practical application of human factor's principles. Due to the significance of this HED, AP&L plans to further evaluate design alternatives. Therefore, the interim corrective action has already been completed and an evaluation is to be performed regarding further corrective action that may be desirable.

The following displays are affected: Panel C-09; IDI LI2618, LI2620, LI2623, LI2624, LI2667, LI2669, LI2671, LI2673.
RESPONSE
C, The identified steam generator displays all presented the level in percent while the operator needs the level in inches. The subject displays were replaced during 1R6 with displays pre-senting the level in inches. This design change was initiated prior to the CRDR program as part of AP&L's continuing commit-ment to the practical application of human factor's prin-ciples. Therefore, this HED has been corrected by a design change to eliminate the discrepancy.

PANEL EQUIPMENT NAME Cl4 DH Cooler E35A/B Cl4 DH Cooler Bypass Cl4 DH Cooler Bypass C13 Reactor CT Loop A/B Cl3 Feedwater Temp Loop A/B Cl3 Steam Gen Downcomer Temp Loop A/B
RESPONSE
O The DH cooler valve demand status indicators have been supple-mented with actual valve position indication lights during 1R6 as part of a design change initiated prior wo the CRDR pro-gram. The design change was initiated as part of AP&L's on-going commitment to the practical application of human factors principles. The other displays identified in this HED are not demand indicators, they are actual status indicators.
Therefore, the discrepancy has been corrected by a design change during 1R6. (See HEDs QS:A3.12-1.045, VR:1-1.017, VR:1-1.017 and VS:1-1.008).

,y N_ CORRECTIVE ACTIONS HED NO.: CK:6-1.001 GUIDE NO.: Section 6 RATING: 1 FINDING:
The control roon instrumentation is not clearly labeled to permit rapid and accurate human performance. Many instruments are unlabeled while others are labeled with inadequate informa-tion. The labels are inconsistent in letter style and size as well as wording, format, abbreviations, and placement. Read-ability is also a problem since many of the labels cannot be read from the required viewing distances.
RESPONSE
['] This HED involves numerous problems with the labeling in the K/ control room. Included are missing labels, dynotape labels, incorrect abbreviations, and numerous other related labeling problems. As part of AP&L's on-going commitment to the practical application of human factor's principles, a program to relabel the control room has already been planned. The development of an integrated guideline document has been completed to provide the needed information for a comprehensive relabeling of the ANO-1 control room. This effort will include use of lines of demarcation and background shading to address other HEDs involving association enhancement. Therefore, this HED is being addressed by a substantial modification program to correct the numerous discrepancies.

i Control Room Design Review ANO-1 CORRECTIVE ACTIONS HED NO.: HR:1-1.002 RATING: 1 FINDINGi On B&W units, it is normal for the main steam relief valve to lift on a reactor trip from high power. There have been cases where these valves do not reseat properly or at the proper setpoint, and no position indication exists to identify this situation.
RESPONSE:_
The need for valve position indication for the main steam O safety valves has already been identified as a design change needed at ANO-1 based on Reg. Guide 1.97. The design change is being developed for installation during 1R7. (See QS:A3.2-1.020, and VR: 1-1.028).

Control Room Design Review ANO-1 gN N- CORRECTIVE ACTIONS HED NO.: QS:Al.17-1.001 RATING: 1 FINDING: -
Atmospheric dump control (CO2) is not separate from condensor ,
dump control, and therefore does not allow individual steam generator HDR pressure control. Presently both have to be transferred if atmospheric dump or condensor valve is selected in auto mode. They automatically transfer, but turbine bypass valve position indicator is not available. The operators, therefore, cannot readily identify the current alignment.
RESPONSE
The control of the atmospheric dump and condensor dump valves has been corrected by a design change implemented during 1R6 as part of AP&L's on-going commitment to the practical application of human factors principles. This design change was initiated prior to the assessment of this HED. The concern about the lack c* position indication for the turbine bypass valves will be evaluated for possible correction.

Manual operation of high pressure injection requires two RO's.
Operation should be simplified to allow one-person operation.
RESPONSE
s The margin to saturation chart recorder is backed-up by a
'k ') digital display on the safety parameter display system (SPDS).
This feature was added to the SPDS as part of AP&L's on-going commitment to the practical application of human factors prin-ciples which was initiated prior to the identification of this HED. The need for two operators was due to the location of the margin to saturation and pressurizer level recorders. The SPDS display was modified during 1R6 to provide pressurizer level with the existing margin to saturation display such that one operator can control the high pressure injection system using this SPDS display. Therefore, this HED has been corrected by a design change. (See QS:A3.14-1.002). ,

Some displays do not span the expected range of operational parameters. The following displays are affected: Panel C-09; IDI FI2218, FI2219, PIS2811, LI1224, LI12620.
RESPONSE
Of the displays identified, only the P7A discharge pressure and the steam generator level indicators created a problem for the plant operators. The P7A discharge pressure indicator had a range of 0 to 1400 PSI and the operator needed a range of at least 0 to 1500 PSI. As a result of a design change already initiated prior to the CRDR program, the display was changed to a 0 to 1800 PSI range during 1R6. This change represents AP&L's continuing commitment to the practical application of
\ human factors principles that will continue after completion of the CRDR program. Therefore, this HED has been corrected by a design change to eliminate the discrepancy.
The steam generator level indicators identified in this HED measured level'in percent with a range of 0 to 100%
(corresponding to O to 396 inches of level). The plant operator expected to see a level of approximately 500 inches corresponding to 100% since that is the location of the upper level tap. During 1R6, these level displays were changed to display a level range of 102 to 500 inches rather than in percent. This change corrected this HED and reflects AP&L's on-going commitment to the practical application of human factors principles that existed prior to the CRDR program.
The other display identified in this HED does not create a problem for the plant operator. The ICW flow indicators (nuc and non-nuc) are sometimes pegged high due to the system being operated at a flow higher than the original design. This is not a problem for the plant operator since the important variable for monitoring ICW performance is temperature which has a display covering the range of operation. Therefore, due to a lack of justification for making a change, no further action is planned to address this portion of the HED.

Setpoints are not established to give the operator adequate time to respond to a warning condition before a problem develops for the following annunciators: EH System Fltr IP14A/lP14B DP Hi; Power Distribution Alarm; EH Fluid System Press Hi/LO.
,o RESPONSE:
( )
- The EH system alarms (differential and hi/lo pressure) were specifically identified due to a problem which occurred at ANO-1 recently involving the EH system. The alarms for the EH system are adequate based on a review of the transient which occurred. The real problem was that an unmonitored filter clogged in the EH system. This situation was resolved by the inclusion of the unmonitored filter in a preventative maintenance program to prevent reoccurance of the clogging problem. An alarm setpoint change for the EH system would not benefit the plant operators since the actual problem involved a filter that is not instrumented.
The power distribution system alarm has been optimized to provent spurious alarms. During a slow transient, the operator is given ample warning that a problem is about to occur.
However, during a fast transient, even a setpoint change would not benefit the operator since there is insufficient time for manual action.
The guideline referenced for thin HED indicates that alarms should allow the plant operator sufficient time to adequately respond to out-of-tolerance plant conditions. Upon a more detailed review, these alarm notpoints are appropriate and do 79 not require changes.

A status display is not provided in Unit 1 to indicate that the item of shared equipment (Hydrogen Gas, Nitrogen, Fire Pump, Emergency Ventilation filter System, Chlorination) is being operated from Unit 2.
RES?ONSE:
- 1. Hydrogen Gas. The hydrogen gas system does not have any controls in the control room for the shared portion of the system. The system is operated locally by manual valve alignments such that control room status of this shared 7- system is not of significant value to the plant operators.
( )
- 2. Nitrogen and chlorination. The nitrogen and chlorination systems do not have any controls in the control room and again are operated locally by manual valve alignments.
Therefore, control room status of these shared systems is not of significant value to the plant operators.
- 3. Fire Pump. The fire pump system is shared by the two units but the controls can only be operated from Unit 1. Since this equipment cannot be operated from Unit 2, the existing control room status display is all that is needed for the plant operators.
- 4. Emergency Ventilation Filter System. The Unit 2 portion of the emergency ventilation filter system is not normally operated from Unit 1. A special case occurs when Unit 2 is shut down and one diesel is out for an extended duration.
At that time the controls in Unit 1 for the Unit 2 Emergency ventilation Filter System are energized and the display (indicating lights) becomes operable on Unit 1.
However, during usual plant conditions, the lack of status display in Unit 1 is not a problem and when status display is needed the Unit 1 display is energized appropriately.

No provisions have been made for identifying the initiating event (first out) associated with automatic plant shutdowns.
Separate first out panels should be provided for reactor and turbine-generator systems.
RESPONSE
w There is a first out panel for the turbine-generator trips.
/ ) This is located on a panel in the back of the control room.
The cause of the reactor trips is available on the sequence of events print-out from the plant computer. This serves the purpose of a first out panel. For AMO, the cause of the turbine trip /or reactor trip is not needed to respond to the events. The procedures for emergencies are based on symptoms and not on identifying the specific accident or cause of the accident. This approach to emergency procedures makes the first out panels useful for post-trip diagnostics only, where time is not critical. Therefore, the existing arrangement for first out panels is sufficient for operator needs and post-trip evaluation.

There is no provision made to indicate lamp failure. During normal operation only one light (out of red / green pair) is lit. If neither is lit you have indication of a lamp failure.
However, there are cases where the red and green lights are both lit.
RESPONSE
( ) The red and green indicating lights are used to verify that a
' ' position change has occurred. In the case of valve indicating lights, both lights are lit when the valve is in the process of changing position such that a light failure would be noticed.
In the case of breakers, the handswitch flag shows the last condition of the breaker such that a light failure would be noticed. Also, the light failure would be identified during the next routine operation of the control since the proper illumination would not occur. Furthermore, the purpose of operating a valve or breaker is to achieve a desired response which is measured in many cases by an independent indicator (e.g., flow, temperature, speed, etc.). By use of the independent indicator the operator can quickly determine the status of a questionable red / green indicating light pair.

Control Room Design Review ANO-1 t HED NO.: CK:5-1.012 CORRECTIVE ACTIONS GUIDE NO.: 5.4.lc RATING: 3 FINDING: i There are double scales on the RC Pressure meters. One scale is used as a backup for the steam table subcooling values. ;
This scale has numbers which do not meet the stroke width ratio requirements.
i l
l RESPONSE:
The scale superimposed on the face of the reactor coolant pressure indicators provides an operator aid for determining subcooling margin. The lettering is intentionally small to prevent obscuring the primary display information of pressure.
Furthermore, the primary display for subcooling margin is provided on a separated dedicated display for the operator's use. Therefore, since the purpose of the superimposed scale is purely as an operator aid, serves as a backup to a dedicated display and is not difficult to read, no further action is planned to address this HED.

The SPDS and GERMS are deficient in providing prompting and structuring features by which an operator can request additional information. An "ALL" or "NONE" output appears to characterize requested system output.
RESPONSE-The SPDS does contain system prompts for the primary displays used by the control room operators (touch-screen features).
The other SPDS features are addressed via the SPDS console.
7_,
These features are primarily the addressable trend points used I
( with the available graphic trend display. These features are

relatively simple to use and the operators hava received extensive training in their use. The addition of more system prompts would be of very little value to the plant operators and would require extensive software changes. Therefore, due to a lack of justification for change, no further action is planned to address this HED for the SPDS.
GERMS is a relatively complex system and has a great deal of operator interaction involved to use properly. Therefore, the need for system prompts is a significant concern on the GERMS.
Based on the complexity of the operator interaction involved with GERMS and the need for a more " user friendly" design for GERMS, a study has already been initiated to evaluate correcting this and other discrepancies with GERMS. This study was initiated prior to the evaluation of the HEDs for GERMS as a result of AP&L's continuing effort to achieve practical application of human factor's principles at ANO. The overall evaluation is to determine whether GERMS should be replaced with an easier to use and more flexible system. Therefore, this discrepancy is to be evaluated for correction per the GERMS evaluation program.

When SPDS and Process Computer numeric data is presented in tabular form, it is appropriately right justified, but decimals do not align vertically unless there are the same number of significant numbers right of the decimal.

Due to this arrangement the steam generator components were arranged in reverse alphabetical order to correspond to the plant layout.
Since that time, the emergency feedwater system has been redesigned and the emergency feedwater pumps supply both steam generators.

The identified meters have been or will be corrected as follows:
- The emergency injection, reactor building spray flow, and decay heat removal flow meters were replaced with
" sigma" type meters that are less susceptible to parallax since they have flat display faces. This design change was initiated prior to the evaluation of this HED are part of AP&L's on-going commitment to the practical application of human factors's principles.

The "EHC Filter Delta P-Hi" alarm comes in too late to allow operators to diagnose the problem and take appropriate action.
The affected alarm is on annunciator box K05, tile B7.
RESPONSE
The specific setpoints for alarm were the EH system filter

'--~
hi/lo pressure) were specifically identified due to a problem which occurred at ANO-1 recently involved the EH system. The alarms for the EH system are adequate based on a review of the transient which occurred. The real problem was that an unmonitored filter clogged in the EH system and not the filter that is monitored. This situation was resolved by the inclusion of the unmonitored filter in a preventative maintenance program to prevent reoccurance of the clogging problem. An alarm setpoint change for the EH system would not benefit the plant operators since the actual proolem involved a filter that is not instrumented. (See HED CK:3-1.002) 4921/a/22 8

Operators indicated that the " RELIEF VALVE OPEN" alarm is not readily distinguishable from the QUINDAR alarm. This may impair the operator's ability to determine the criticality of the alarm involved.
RESPONSE
() The electromatic relief (ERV) and QUINDAR alarms are behind the main operating area of the control room. The ERV alarm is accompanied by a front panel annunciator indication.
Therefore, the plant operator at the control boards can quickly determine the source of the alarm based on the visual indication. Since the visual and auditory alarm work together to eliminate operator confusion, no further rction is planned regarding this HED. (See CK:2-1.003).

Operators indicated the " CORE FLOOD TANK OUTLET VALVE INTER-LOCK" alarm and QUINDAR/ computer alarm cannot be readily dis-tinguished from each other. This may impair the operator's ability to determine the cause of the alarm.
RESPONSE
7s i ) The " CORE FLOOD TANK OUTLET VALVE INTERLOCK" and QUINDAR alarms are behind the main operating area of the control room. The outlet valve position indication is provided on the front panels (C-16/C-18). Furthermore, the only time the interlock alarm is useful is during heat-up/cooldown at which time the operator is especially interested in the valve interlock status. Therefore, the visual aid of the valve position indication and the operator's special interest in the valve interlock alarm makes the rapid determination of the source of the alarm possible such that operator confusion is not a problem.

During Task Analysis, the Subject Matter Expert stated that a control status light for gland seal steam supply valve position indication is needed for the task but is not available.
RESPONSE
The supply of gland seal steam is from the startup boiler via c ~s manual valve lineup during plant startup and is transferred
( ) manually to the main steam system as the unit goes into power operation. The operator does not need a gland seal steam supply valve position indication since the valves are controlled by manual operator action. If the plant trips during startup and the operator doesn't know if the gland seal steam is being supplied from the startup boiler or the main steam system, he can watch the gland seal steam pressure annunciator to determine status. If the alarm comes in, he sends an operator to open the startup boiler supply valves.
