Review of IR 321,366/88-12 Concerns a.

Verification and Validation IR 321,366/88-12 noted that the supporting documentation for the EOP development process and formal validation was'under contractor control.

The team observed that the supporting docume.Ttation was now located in the

,

'

onsite document control system.

IR 321,366/88-12 also noted that formal validation for those EOP steps not exercised on the simulator did not include a walkthrough of the procedures in the plant.

The team reviewed the current practice for EOP steps that cannot be validated L

on the simulator.

This method required a wal.;through if simulator validation was not possible.

The tible top reviewr will only be used if the EOP cannot be validated on the simulator or walked through.

Additionally, IR 321,366/88-12 noted that EOP validation and verification on the ARPs and AOPs that implement the PSTG was minimal.

The team found that AOPs, ARPs, and interfacing ops are generally not validated on the simulator, however, the procedures no longer implement PSTG requirements.

Administrative control procedures for EOP validation and verification programs (30AC-OPS-011-OS and 30AC-OPS-006-OS) were reviewed.

Both documents were found to

~ adequately specify a multidisciplinary team approach to V&V.

V&V records for the Revision 4 EOPs were reviewed on a sample basis and showed evidence of a multidisciplinary team approach.

b.

Radiation Release Control IR 321,366/88-12 identified two deficiencies with radiation release control.

These deficiencies had been corrected as follows:

The EPIP was pre"lously identified by licensee documents as a source of jnstructions for radiation release control, but the facility was unable to identify the specific instruction in the EPIP which addressed EPG steps.

The subsequent EOP upgrade to Revision 4 of the BWROG guidelines included instructions within the secondary containment charts for controlling radiation releases.

The EOP upgrade also resolved the failure of previous precedures for radiatjon release to address a radiation release at the alert level pre-scram that may occur as an unmonitored relear.e.

The licensee has deleted the pre-scram.

Now if conditions exist that constitute

.

i

-

,..

,

.

.

reaching radiation release levels, the flow charts will be entered.

c.

Deviation Documentation and Use of the PSTG as a Technical Basis IR 321,366/88-12 noted a common source for the inspection findings appeared to be that the facility considered the PSTG as a guideline whereas the NRC considered the PSTG as the technical basis upon which to develop the EOPs and upon which their technical adequacy is judged.

The team determined that the licensee now considers the PSTG as the technical basis for the development of the EOPs.

The PSTG had been revised and now implements Revision 4 of the BWROG EPGs with 13 documented plant specific deviations.

The current EOPs were then developed from the PATG with no technical deviations, but with some human tector differences.

There were no differences-in logic or accident mitigation strategy.

IR 321,366/88-12 noted that there was no documentation available to justify the deviations from the PSTG and

!

.the BWROG EPGs.

The team observed that the licensee had developed a technical deviation document which addresses the differences between the PSTG and the BWROG EPGs.

IR 321,366/88-12 also noted that there was no documentation available to justify EOP differences from the PSTG.

The team observed that the licensee had developed a document that delineates the differences between the PSTG and the EOPs.

The documentation of the differences was not always detailed enough to determine if adequate engineering analysis had been performed for j

some of the deviations (B II).

Additionally, a comparison between the flow charts and the PSTG documented in IR 321,-366/88-12 revealed

'

.several concerns with the details of the Plant Hatch

.

EOPs._

The team reviewed a sample of the new flow charts and, with the exception of the comments noted.in Appendix B (B II), the flow charts were found to be adequate.

Technical inadequacies in EOPs identified in Appendix B will be followed up under IFI 321,366/90-16-03.

d.

Operator Action Setpoints 7.R 321,366/88-12 noted that the values for parameters involving action steps in the EOPs were often not the same as those specified in the PSTG.

The team-reviewed

-

the deviation document and observed that the setpoints that were different were now described in that document.

l

I,

,-

'.

,

'

.*

Additionally, IR 321,366/88-12 noted that the limits specified in Path 3 of the EOP flow charts were inconsistent with the PSTG.

The flow charts have been

,

completely rewritten and the problem was corrected except as noted in Appenlix B (B II).

Technical inadequacies in EOPs wi.'.1 be followed up under IFI

'

321,366/90-16-03.

This inspection, however, noted several additional problems vith the control of operator setpoints, particularly in EOP-14.

The incorrect setpoints indicated ar ineffectivo program for the control of changes to EOP setpoints.

The correct information was located in at least one of the multiple documents that contained the setpoint information.

These discrepancies were not detected during the licensee's EOP review process. Additionally, differences between the EOP setpoints and the-EQ program values were noted.

The details of these differences are described in Appendix B (B II).

The instrumentation for some EOP setpoints were set inappropriately in the field.

An example of this was the alarm setpoints for the E11N600 instruments for the Unit 1 Maximum Normal Values (temperature) for the diagonal' rooms.

The Maximum Safe temperature values for RCIC, HPCI, and the steam tunnel inconsistently referred to the EQ data for maximum room temperature in that some of the Maximum Safe Operating temperatures did not correspond with the EQ room temperature profiles, r

The hi-hi level column on table 5 of EOP-14 referred to the incorrect alarm setpoints.

For example the hi-Pi-hi value was reference 1 instead of the hi-hi value, and the i

setpoint given in tlo ARP did-not correspond to the EOP setpoint, the actua) instrument setpoint, or the instrument setpoint index.

The inappropriate setpoint change methodology and the incorrect EOP setpoilts are identified as IFI 321,366/90-16.

e.

Entry and Exit Conditions The licensee's previous set of EOP' procedures consisted of ARPs, AOPs, Flow Charts, EPMs and EPIPs.

Each of these procedures contained procedural guidance from the EPG.

All were_ required to implement the symptom based EOPs.

The operators would enter an ARP, then go to an AOP, then if necessary direct a scram, at which time the flow charts were entered.

During this lengthy process, conditions such as adverse containment pressures or

I,

.

.

,

.*

radiation levels could unnecessarily continue without attention from the operator until the operator could progress through the EOP.

The licensee's revised EOPs do not rely on APPs or AOPs to accomplish emergency mitigation.

The EOPs now consist of eight flow paths augmented by twelve supplemental procedures.

Any occurrence developing the PSTG entry conditions, with or without a scram, will immediately cause the operators to enter a specific EOP flow chart to mitigate that emergency.

f.

Procedure Administrative Controls 1)

Administrative Controls for ARPs and AOPs IR 321,366/88-12 noted that the administrative controls for ARPs and AOPs were not the same as EOPs.

It stated they should be since the old'

ARPs/AOPs implemented PSTG requirements.

Discussions with the licensee indicated that there

,

are no EPG actions remaining in the ARPs or AOPs.

Therefore, they need not be subject to the same administrative controls.

2)

Ongoing Evaluation of EOPs IR 321,366/88-12 reported that the individual conducting the annual review of EOPs was not required to sign the review sheet, and that there were no specific requirements which provided the bases for the annual review.

The team reviewed the two documents that control this annual review, (30AC-OPS-007-OS and 10AC-MGR-003-OS) and. concluded that these problems had been corrected.

3)

Operator Feedback IR 321,366/88-12 noted that operator feedback was

not actively solicited during EOP training.

Discussions with the licensee revealed that operator feedback was actively utilized during EOP Revision 4 development and is currently being used in operator training.

4)

QA Involvement IR 321,366/88-12 noted that a QA audit of EOP flow charts and end path manuals resulted in similar findings to that of the EOP inspection team.

l

,

i.

.

.

,-.

,

'

s

The concern was that an in-depth review of root cause was not accomplished.

Also cited was what was considered inadequate followup action regarding how _

,

widespread these concerns were.

L L

The team discussed this finding with QA personnel to determine its current status and to determine the current extent of QA involvement in the EOP program.

These findings and corrective actions included:

a)

The initial EOP inspection occurred during the middle of the corrective action cycle for the QA

,

audit dated September 15, 1987.

Corrective action was complete by December 21, 1988.

A followup QA audit-was then satisfactorily accomplished.

b)

QA personnel stated that EOPs have been and will l-be covered as part of the Operations audit. The L

inspection team reviewed the Audit Planning schedule and verified the EOP portion is planned

.

to occur at least on an annual basis.

I c)

The next EOP audit is scheduled in 1991 as part l

of the Operations audit.

QA personnel explained

'

that the audit would most likely consist of a review of celected EOPs against WG 11.

'

d)

As part of the Procedure Controls audit, QA l

conducts an audit to ensure that the Operations Department is conducting annual reviews of EOPs

'

l as required by 10AC-OPS-006-OS.

e)

Adequacy of EOPs are also covered by other audit types such as simulator certification and training audits.

5)

Quality of Control Room Drawings and Procedures Paragraph 11 of IR 321,366/88-12 identified deficiencies in the quality of various types of f

emergency procedures in the control room.

Review of this area during this inspection determined that the AOPs, ARPs, supplemental EOPs, and EOP flow charts

,

were legible, well organized and were neatly filed and tabbed.

g.

Labeling and Nomenclature The executive summary and paragraph 5 of IR 321,366/88-12 identified a concern regarding inconsistency between

.

'

.

p

.

.

,...

L plant labels and emergency procedure nomenclature.

Review of this area during this inspection by followup L

of previously identified deficiencies and by review of

additional procedures determined that the labeling problem addressed in the previous inspection had not been corrected (B II).

This item will be reinspected in a future inspection under IFI 321,366/90-16-01.

h.

Support Equipment The team noted during walkthrough of the flow charts and supplemental procedures that tools and equipment needed

,

,

to implement the EOP mitigation strategy were dedicated L

for "EOP use only" and were readily available and I

clearly tagged indicating location and use.

Once the operators. progressed through the flow charts to the supplemental procedures, the supplemental procedures contained steps directing the operators to install l

jumpers and/or to disconnect leads from designated

,

locations within control panels.

The team noted that once the operator entered the control panels, each ccnnection was clearly identified by a pink " possum vail".

These possum tails were immediately noticeable l>

atd were clearly. marked as to connection points.

t 1.

Simuistor Observations The inspection team observed four scenarios performed by the licensee in order to verify the adequacy of several l

of the.EOPs and their supplementary procedures.

The

scenarios involved (1) a loss of all feed requiring-steam cooling; (2) loss of high pressure feed /

injection with core spray / lowering suppression pool level; (3) loss of drywell chillers / emergency depressurization; and, (4) total loss of AC for greater

,

than 15 minutes.

The inspection team concluded that the L

EOPs and supplementary procedures utilized-in these scenarios were adequate to accomplish accident mitigation.

j.

Human Factors The primary human factors concern.of IR 321,366/88-12 was the overall complexity of the flow charts.

This complexity resulted in procedures that were difficult to use, understand, and read.

The major contributing factor to this complexity was the high level of detail found in the procedure..

'

,...

.

.

.. <

These initial concerns can be summarized as follows:

1)

Inconsistent transition methods 2)

Inconsistently structured decision steps 3)

Unnecessary memory demands on operators 4)

Improper use and placement of notes and cautions 5)

Poor graphics - inadequate print size, lack of white space, light glare on charts, low color contrast 6)

Complex sentence structure 7)

WG inadequacies 8)

Lack of placekeeping methods 9)

Inadequate table space In general, the inspection team found that the new Revision 4 procedures are significantly improved in all of the above areas, k.

Complexity of EOP Flow Charts Paragraph 8 of IR 321,366/88-12 indicated that the complexity of the EOP flow charts required a substantial amount of training in order to properly train operators in their use.

This paragraph also indicated that the operators considered that the flow charts provided more detail than was required to adequately perform the procedures.

The executive summary of IR 321,366/88-12 contained numerous examples of' human factors concerns.

Simplification of the flow charts under the licensee EOP upgrade project, as described in paragraph 4'.a.,

resolved these concerns.

1.

Containment Venting The IR 321,366/88-12 team noted that the 2 inch flow control valves for the containment vent valves were not environmentally qualified and that there were several differences between the Unit 1 and Unit 2 containment purge lines.

This inspection determined that the purge paths had been revised and were the same for both units.

The emergency containment venting procedure and methodology has been revised to include a drywell destructive vent path which will vent the suppression.

pool or the drywell into the reactor building in the event that pressure cannot be maintained below 49 psig.

This flow path is through duct work that is~ designed to fail and vent to the reactor building.

The SGTS will

!

then be aligned to the reactor building to process the l

released gasses.

l l

l I

.. -

..

.

'.

.<

IR 721,366/88-12 noted that excessive drywell pressure could close.the excess flow isolation dampers'in the 18 inch SGTS forcing the flow through the two inch bypass line around the damper.

The team reviewed this and determined that this existed to prevent damaging SGTS.

As described above a destructive vent path has been included in the venting procedures to allow the use of SGTS if drywell or suppression pool pressure exceeds 49 psig.

In a letter to NRC dated October 24, 1989, the licensee voluntarily committed to jnstall a hardened vent to reduce the risk associated with the long term loss of decay heat removal.

The licensee will work with.the BWROG to develop specific and generic guidelines for the installation of these vents. The current schedule indicates that the vents will be installed at the end of cycle 14 on Unit 1 and the end of cycle 10 on Lnit 2.

There were no violations or deviations identified in this

+

area.

3. Review'of the SER on Procedure Generation Package a.

Plant Specific Technical Guidelines i

The SER stated the PSTG should be revised.to conform with Revision 4 of the BWROG EPGs.

The SER further stated that safety significant deviations should be documented, justified, and archived for future reference.

The team reviewed the completed documentation and determined that'with the exception of the comments detailed in Appendix B (B II), the licensee

'

'

had completed these tasks.

b.

Writer's Guide The inspectors found that the new EOP WG provides sufficient guidance to provide for consistently prepared-and revised, high quality'EOPs. Specific concerns delineated in paragraph 2B of the SER have been either adequately addressed-in WG-11 or are no longer applicable to Revision 4 of the EOPs (C II).

c.

Procedure Generation Package Paragraph 2.B of the SER on the PGP included several additional comments for licensee consideration in revising the PGP.

The details of these comments are addressed in Appendix C (C IV) to this report.

The licensee had taken appropriate action on all of the SER comment,

.

'

..

'.

.

.

,

d.

Verification and Validation The team found that the licensee had adequately addressed the SER items on V&V.

The details of these actions are in Appendix C (C III).

j e.

Training The team found that all issues raised in the SER had j

been adequately resolved by the licensee in current administrative controls and practices (C III).

The team j

noted that changes had not necessarily been made to the

-

PGP since it is not and was not required to be kept

updated.

There were no violations or deviations identified in this area.

4.

Review of Updated Procedures a.

Flow Charts and Emergency Procedure Guidelines The team noted that the legibility of the EOP flow charts had significantly improved since IR 321,366/88-12.

The most significant technical difference was a.

total rewrite of all EOPs to closely follow the EPGs.

The flow charts were well organized and the operators interviewed demonstrated a comprehensive knowledge of the flow paths.

The enlarged print size and increased use of white space has significantly improved readability and useability of the BWROG EPG Revision 4 flow charts.

b.

Other Techt.ical differences exist between the EOP and RCIC operating procedures for actions taken to initiate

,

alternate boron injection.

Details are contained in

'

Appendix B~(B II).

This item will be reinspected in a future inspection under IFI 321,366/90-16-03.

There were no violations or deviations identified in this area.

5.

Followup of Licensee Long-term Operational Upgrade Efforts The licensee voluntarily initiated a program in April of 1988 to upgrade certain aspects of operational performance.

Long-term operational upgrade efforts in the areas discussed below were reviewed during this inspectio.

,

'

..

.

.

'

.

a.

Consolidation or Elimination of Notes, Cautions, and

,

Restorations L

Item 4.a of the 1988 EOP improvement project committed i

l the licensee to consolidate or eliminate fire notes, o

cautions, system restorations and system operations from the EOPs. The following has been accomplished in-the L

Revision 4 EOPs:

,

1)

Fire notes have-been eliminated from the flow charts and are contained in the fire procedure.

2)

Instructions on operation of systems operator and l

system restorations are now referenced in-the appropriate system operating procedures and I

supplemental procedures.

l 3)'

Caution' summaries now appear in the flow path with l

detailed caution statements at the bottom of the

'

flow chart.

This item is closed.

i b.

Minimize Steps Item 4.b of the 1988 improvement project committed the licensee to minimize the steps in the EOPs.

The team reviewed Revision-4 of the EOPs and determined that the

,

licensee had complied with this commitment.

This item

!

is closed.

.

-

c.

Language Improvements The licenses committed-to improve the language of EOPs as item 4.c of their 1988 EOP improvement project in order to provide consistent operator response to plant events.

The new EOPs closely follow the EPGs and the majority of the wording is extracted exactly from the l

EPGs.

Improvements have also been made in the licensee's WG for preparing the EOPs.

This item is closed.

d.

Expand Print' Size The inspection team assessed the licensee's corrective actions associated with item 4.d-of the licensee's 1988 EOP. improvement plan.

This was identified as (long.

term) action to expand the print size of the EOP flow paths. -The team noted that adequate print size enlargement, which facilitates the usability of the flow charts, had been accomplished.

!

l-cables entering the main control room. panels from the

',

cable spreading room that do not appear to be tied off

'

to the cabinet in a way that would prevent loading other previously run cables or loading the state-blocks to which wiring is terminated.

l The licensee conducted a review of related industry I

situations and conducted a walkthrough to assess the j

extent of the noted conditions.

The results were to

'

receive an engineering evaluation with subsequent corrective actions initiated.

The inspection team's review noted that the results of

!

l the licensee's review determined that the cables that

'

appeared to be too tight did not have a potential for j

differential movement and would not be affected during l

or following a seismic event.

The licensee's evaluation i

results are considered to adequately address the concern of this IFI.

However, this same licensee review noted that the cables which were " unsupported or pulled too tight as described in this IFI should be modified to comply with Plant Hatch Procedure (52CM-MEL-003-05]"..No such procedure exists; however, procedure 52GM-MEL-003-OS,.

Cable / Raceway Installation and Cable Terminations does apply.

Tne team noted that documentation does not exist

,

that substantiates that the cables.have been evaluated

and corrected as necessary=to meet procedural requirements.

The licensee's corrective actions to address modifying the cables to meet procedural requirements will be inspected during a future inspection and will be inspected under IFI 321,366/90-16-04.

APPENDIX B Technical and Human Factors Comments This appendix contains technical and human factors comments and observations.

Unless specifically stated, these comments are not regulatory requirements.

However, the licensee acknowledged that the factual content of each of these comments was correct as stated.

The licensee further agreed to evaluate each comment, to take appropriate action and to document that action.

These items will be reviewed during a future NRC inspection.

I.

EOP Example Closeouts from IR 321,366/88-12 1.

Paragraph 4.b, example 1 a.

This example noted that comparing the mitigation of a low level entry condition on Path 3 of the EOP flow charts (the normal SCRAM procedure) with the low level response of the PSTG contained variances in steps and setpoints.

Most notable of these variances was that flow Path 3 had the operator proceed through forty-three steps before asking if level could be maintained above +12 inches and if not directing the operator to proceed to Path 4.

The inspection team determined from a comparison of the EPG and the revised EOP flow chart, 31EO-EOP-010-2S, coupled with a walkthrough, that the flow chart adequately follows the guidance of the EPG and that previous variances between the EPG and the EOP flow path were corrected.

2.

Paragraph 4.b, example 2 a.

IR 321,366/88-12 noted problems with the entry conditions for RPV pressure control.

The team reviewed the current mitigation strategy.

The entry conditions were appropriate.

3.

Paragraph 4.b, eyample 3 a.

IR 321,366/88-12 noted several discrepancies between the PSTG and the EOP for monitoring and control of reactor power.

These problems were not observed by the team.

4.

Paragraph 4.b, example 4 i

a.

This item reported that the RPV flooding EOP accounted for non-isolation of HPCI and RCIC when they were being used for boron injection but that this action conflicted with the PSTG.

Review of the revised RPV flooding flow chart and the associated

_

.-

$.

,.r

.

..

Appendix B

portion of the revised PSTG determined that they

,

were in agreement concerning isolation of HPCI and RCIC, and both were in accordance with the EPG.

5..

Paragraph 4.b, example 5 a.

This item reported a conflict between the PSTG and

,

the EPM concerning operator actions on high suppression pool level.

Review of the new PSTG and EOP flow chart determined that they were-in agreement and also agreed with the EPG.

,

6.

Paragraph 4.b, example 6 a.

This item reported that. flow chart 1, Caution 21

provided an entry condition for hydrogen contrary to the PSTG.

The new Primary Containment flow chart

and the new PSTG provided this requirement and agreed on the hydrogen value.

7.

Paragraph 4.b, example 7 a.

This item. reported that flow chart 1 and the PSTG conflicted concerning SBLC initiation considering suppression pool temperature.

Review of the new RCA RPV. Control (ATWS) flow chart and the new PSTG determined that they were in agreement concerning SBLC initiation, and agreed with the EPG.

8.

Paragraph 4.b, example 8 a..

This item reported that the PSTG included an entry condition into Secondary Containment Control that was not included in the EPM.

Review of the new PSTG j

and the new Secondary Containment Control flow chart

determined that the entry condition was included in both documents, and that the-entry condition agreed with that specified in the EPG.

9.

Paragraph:4.b, example 9 a.

This item reported a conflict between PSTG Caution 14 and EPM 4.125 concerning operator actions related to RPV depressurization and a check of the availability of low pressure motor driven injection systems.

This check was not included in the new PSTG or the new flow charts due to the fact that Revision 4 of the EPG deleted this requirement.

Appendix B-3'

10. Paragraph 4.b, example 10 a.

This item noted that in the primary and secondary containment control procedures ~both pre-scram and in the EPM, concurrent control of all containment

_ parameters-(i.e., suppression pool temperature, L

suppression pool level, and containment pressure)

were not procedurally required whenever an entry

.

'

condition existed as provided for in the PSTG.

The licensee _has deleted both.the pre-scram procedures and the EPM.

The revised flow charts for

primary and secondary containment control specify

>

I concurrent control of all containment parameters (i.e. suppression pool temperature, suppression pool level, and containment pressure).

11. Attachment B, paragraph A a.

IR 321,366/88-12 stated that the EOP equipment

,

cabinet was inspected weekly.

The team found the current practice for the inspection of all EOP

'

required equipment to be adequate.

EOP equipment was stored in a variety of locked containers.

The i

tamper. seals were inspected monthly and the contents of the storage containers are inventoried annually.

After a review of previous EOP equipment practices, 4.t was determined that this was the method that was in place at'the time'of IR 321,a66/88-12.

12. Attachment B, paragraph B a.

Sex cal minor comments were identified in IR 321,366/88-12-on the walk:through of the Containment Control Guideline,.Drywell Pressure and Temerature Control procedures._ The team reviewed these comments and determined that they had been adequately resolved.

13. Attachment B, paragraph C

a.

The problems identified in this paragraph concerned operating procedures 34SO-E41-001-2S (HPCI system)

and 34SO-E51-001-2S (RCIC system) which are no longeria part of the EOPs.

Procedure 31EO-EOP-109-2S'took.the place of these procedures.

P,rocedure 31EO-EOP-109-2S was walked through during this L

I inspection.

procedure but were not present on control room placards. Exampics appear in steps 3.1.1.4.1, 3.3.5, 3.4.5.

b.

Step 3.7.3 substeps 2 and 3:

These steps required the operator to determine primary containment level and drywell pressure respectively.

There are

numerous methods and indicators that can be used.

A summary list of acceptable methods / indicators was not included as a memory aid to the operator.

.

15, 34SO-E11-010-2S a.

General comment:

The suppression pool was referred H

to as both the suppression pool and the torus at various points in the procedure.

The reference to this system was not consistent.

This also does not match the labeling on the control room panels which refer to the torus, b.

Steps 7.2.5, 7.4.7.4.1, and 7.4.7.5.1:

These steps can be entered from the steam condensing mode of

'

RHR, per EOP-107, page 16.

The conditions for entry from this mode was not included in these steps.

16. 34SO-E21-001-2S a.

Stop 7.4.2.3 This step required the operator to confirm that the CST level was greater than 15 feet.

The definition of confirm was "if it is not that way make it that way".

Without BOP power available the operator would be unable to fill the tank if the level was low.

The demineralized water storage tank transfer pumps are powered from DOP sources.

j b.

Step 7.4.3.4:

This stop required the operator to confirm that the CST level was greater than 25 feet.

The definition of confirm was "jl it is not that way make it that way".

Without Bor power available the operator would be unable to fill the tank if the level was low.

The demineralized water storage tank transfer pumps are powered from BOP sources.

c.

Steps 7.4.2.4, 7.4.2.7 and 7.4.3.7:

These steps contained an infrequently operated valve that required local operation.

The valve location and the fact that the valve required local operation should have been included in those steps, d.

Section 7.4.2 and 7.4.3:

These sections could not be accomplished as written if BOP power was not available.

Specifically, the AOVs fail open and the p t~-

General comment:

Throughout this procedure H202 (Hydrogen Peroxide) was used to identify Hydrogen l

and Oxygen.

The better nomenclature may have been H2 and 02.

b.

General comment:

There were labeling deficiencies (i.e., the component label did not match the EOP) in the following parag'taphs of this EOP 7.2.1, 7.2.4.1, 7.2.4.3, 7.2.5.1, 7.2.5.3, 7.3.3, and 7.3.4.

L c.

Step 6.53 This step listed a primary containment

H2O (water) analyzer.

This step may have more appropriately referred to a primhry containment H2 and 02 analyzer.

d.

Steps 7.1.1, 7.2.2, 7.3.1 and 7.3.2:

These steps referred to a mode switch on 2P33-P601A.

There was no mode switch on-this panel.

The steps may have more appropriately referred to a selector switch.

APPENDIX C Details of SER and Human Factors Concerns I.

HF Concerns The inspection team found no new human factors items of concern other than the labeling / nomenclature concerns discussed in Appendix B.

II. SER - WG Comment Resolutions All SER WG comments have been adequately addressed through dc/olopment of the new EOP WG (WG-11) or the comments are no longer applicable as a result of the new Revision 4 EOPs and supplemental procedures.

III.SER - V&V and Training Comment R3 solutions 1.

SER item C.2.a:

a.

This item stated that the PGP should be expanded to include the critoria for selection of the verification team and clearly identify their roles and responsibilities, A new verification proceduro was written which roc'uired a multi-disciplined team consisting of, as a sinimum, human factors engineering, EPG generation, EOP generation, and Operations personnel.

2.

SER item C.2.b e.

This item stated that the PGP should be expanded to include a clear explanation of what criteria would indicate a need for involvement of a team of exports from other disciplines and what capabilities they

,

should possess.

A now validation procedure has been written which accomplished this task.

,

3.

SER item C.5 a.

This item stated that the V&V program proposed by

'

the licensee was adoquate, but that procedures 30AC-OPS-006-OS and 30AC-OPS-003-PS needed to be

reviewed.

The team reviewed these procedures and found that they were adequate.

4.

SER item C.6.a:

a.

This item stated that section 3.7 of the PGP, pages 17-21, did not incorporate the response and it should be expanded accordingly.

This item had been corrected.

Appendix C

5.

SER item C.6.bt a.

Thir, item stated that the PGP should include the e*propriate criteria for determining the type of f

validation required.

The walkthrough validation method has been incorporated into the current procedure which will be used for validation of the procedures that cannot be validated on the simulator.

The table top method will only be used when no other method is available.

6.

SER item Dt a.

The SER stated that the PGP did not address directly the issue of minimum shift complement required by the Technical Specifications.

The PGP requires that all EOPs be written such that they can be performed by a Technical Specifications minimum crew size.

The licensee has elected to train their operators with a crew that is one greater but which is more representative of expected accident conditions.

The team observed simulator scenarios and reviewed the licensee's PGP section 3.2.

They found staffing levels to be both consistent with current training practices and adequate for efficient use of the EoPs in mitigating accidents.

IV. SER-PGP Comment Resolutions 1.

Paragraph 1.a (page 8)

a.

This item reported that the WG (subsection 8.1.C 3.2) should be revised to define the phrase

"other actions as determined necessary" in providing requirements for EPMs.

The WG no longer addresses

'

EPMs.

The new section of the WG concerning supplementary EOPs does not include a phrase similar to the above.

2.-

Paragraph 1.b (page 9)

!

a.

This item reported a problem concerning section access of EPMs and also addressed the need to l

standardize where entry conditions are maintained so L

that they are readily visible to the operator.

EPMs

'

were no longer being used by the licensee.

The entry conditions for supplementary EOPs only required entry as directed by_the flow chart I

Appendix C

i 3.

Paragraph 1.c (page 9)

a.

This item repci-tcd that the WG did not provide specific criteria for 1.ine spacing to enhance legibility of the flow charts.

Review of this item determined that the WG still did not provide this criteria, however, the readability of the new flow charts was greatly enhanced.

This Itum is closed.

4.

Paragraph 1.d (page 9)

a.

This item reported a lacP. of controls in the WO over the use of capitalization.

Review of this iten determined that capitalization requirements were included in paragraph 2.11 af the new WG.

5.

Paragraph 1.c (page 9)

a.

This item reported that the WG did not requi?le units of measure in EOPs to match the units of measure on plant instrumentation.

Review of this item determined that paragraph 2.5 of the new WG required EOP units to match the plant instrumentatien units.

,

6.

Paragraphs 2.a through 2.d (page 9)

a.

These paragraphs provided administrative comments on the organization of the PGP package.

The PGP at Hatch was rect a living document.

The PGP was specifically put together from other conttviled

'

documents for a one time submittal to the NRC.

Each of the individual documents was revised as necessary to provide required controls, but the PGP as a whole was not revised.

As a result the SER comments were not applicable.

The teau found this to be acceptabl,
