3.

DISCUSSION OF ANALYSIS The 0.

C.

Cook Plant design has been reviewed with respect to the reference plant analyses which were performed to support the development of the generic ERGs.

This review has confirmed that the reference analyses are applicable to the 0.

C.

Cook Plant and that no additional analysis is required to support the use of the ERGs in developing plant specific procedures for the 0.

C.

Cook Plant.

The reference plant for many of the analyses is a standard 4-loop non-UHI plant, but the analyses are intended to be generic and applicable to all Westinghouse-designed commercial PWR plants to the maximum extent practicable.

Since the 0.

C.

Cook Plant is similar to the reference plant, many of the analyses are directly applicable to D.

C. Cook.

Although the 0.

C.

Cook Plant has an ice condenser containment system compared to the dry containment system for the reference plant, this difference does not affect the applicability of the analyses for 0.

C. Cook.

At the same time, note that these ice condenser design features have been incorporated into the 0.

C.

Cook EOPs.

For those cases where the analysis is not directly applicable to the D.

C.

Cook Plant, a comparison of the system design and plant parameters demonstrates that the reference analyses are bounding for the

.- 0.

C.

Cook Plant, and that the conclusions are applicable to the D.

C.

Cook Plant.

(Analyses performed for a four loop reference plant were considered to be directly applicable to the DCCNP without any additional evaluation.

References analyses performed for a three loop plant required an evaluation of system designs and plant parameters to demonstrate that the analysis results were bounding for DCCNP.)

4.

BASIS FOR USING THE GENERIC WESTINGHOUSE ERGs To the greatest practicable extent, the Westinghouse Emergency

Response

Guidelines (ERGs) have been constructed to be generic and applicable to all Westinghouse-designed commercial PWR plants.

It can be seen from the comparison made in Section 2 that the D.

C.

Cook plant is very similar to the reference plant, which was used as the basis for developing the ERGs.

Also, as noted in the analysis discussion provided in Section 3, the analysis performed to support the generic ERGs is also applicable to the D.

C.

Cook plant, and no additional analysis is required.

Therefore, the D.

C.

Cook EOPs will be based upon the generic Westinghouse

ERGs, HP-Revision 1.

When writing the EOPs, modifications to ERG steps must be made to account for the D.

C.

Cook plant design differences which are delineated in Section 2.

6924S/042586

METHOD FOR DEVELOPING EOPs FROM ERGs 5.1 General The generic Westinghouse Emergency

Response

Guidelines (ERGs),

Revision 1 will be used as the basis for writing the EOPs for the D.

C.

Cook Nuclear Plant Unit l.

A final list of the Revision 1

ERGs is included as Appendix B.

This section describes the method that will be used to convert the generic guidelines into EOPs.

The EOP writing team will obtain and review the following source documents for D.

Calculated Mathematical Values used in EOPs (included in Background Information Manual) 5.3 Hethod The EOP writers will follow the ERGs step by step.

The writer will research the source documents and then construct the EOP and an associated EOP Documentation Form (Appendix C).

This D.

C.

Cook

Background

Documentation Form will list how each generic guideline step is used in the EOP and also list any additional steps added to the EOP with its basis, if applicable.

Any difference'etween the 6924S/042586 13

5.3 Method (Cont.)

ERG step and the D.

C.

Cook step will be explained.

This form along with the calculation for mathematical values used in the EOPs will be kept in the Background Information Manual for the D.

C.

Cook EOPs.

The following additional instructions for writing the EOPs and completing the EOP Documentation Form are provided.

l. If the generic step is compatible with the D. C.

Cook plant

design, then the step should be copied into the D.

C.

Cook EOP.

Since the technical basis for the step is explained in the ERG

Background

Document, there is no need to repeat this on the background documentation form.

2.

When an ERG step specifies a numerical value to be calculated, the value will be determined and put into the D.

C.

Cook EOP.

The documentation form should indicate where the method of derivation is located.

3.

When an ERG step requests plant specific details or actions to be added to the procedure, add the information to the procedure.

However, if the operator actions are highly routine or well within the knowledge of the operator, the specific information should not be included.

The reason for this should be explained on the documentation form.

4. If the ERG guideline fails to identify or address systems or actions that are unique to D.

C.

Cook (Refer to Appendix A), then steps should be included to encompass the necessary actions.

These should be explained on the documentation form/

5. If an ERG step spe'cifies an action that cannot be performed at D.

C. Cook, the step will be deleted or modified and the reason explained on the documentation form.

5.3 Hethod (Cont.)

6.

If an ERG step is modified such that the intent of the step is

changed, then the basis will be explained on the documentation form.

7.

Minor modifications to ERGs steps are acceptable without extensive Justification provided that the change does not alter the intent of the guideline.

Examples of these types of changes are as follows:

a.

Deletions of level of detail (see item g3).

b.

Rewording of ERG steps to conform to standard D. C.

Cook terminology, abbreviations and acronyms.

c.

Rearranging ERG steps to streamline the procedure due to D.

C.

Cook control room design and for operator convenience.

• All additions to and deletions from generic guidelines were verified/

validated as part of the EOP verification/validation program.

Part of the verification/validation procedure is to check the plant specific procedure against the generic procedure and ensure that; all additions and deletions of information are documented and analyzed and also that the order of steps (if changed) remains within the bounds of the step sequencing table (part of generic background information).

APPENDIX A COMPARISON OF SYSTEM DESIGNS FOOTNOTES:

(1)

No impact on the structure of D.

C.

Cook EOPs.

(2)

ES-1.3 and ES-1.4 should be written to include the plant specific transfer to cold and hot leg recirculation procedure, which is included in the D.

C.

Cook SIS System Description.

(3)

The containment spray heat exchangers are utilized, if needed, during the recirculation phase.

Therefore, cooling water to the containment spray heat exchangers is required during the recirculation phase of a LOCA when containment spray is required.

ES-1.3, ECA-l.l and FR-Z.l should be written to include this design feature.

(4)

The D.

C.

Cook design has spray capability using the RHR pumps.

RHR spray should be initiated if the containment pressure exceeds 8 psig following the initial blowdown.

Also, RHR spray should not be used until the accident has progressed to the point when the ECCS is in the recirculation phase, or at least 30 minutes after the accident.

RHR spray is in'addition to the spray supplied by the containment spray pumps.

The addition of RHR spray capability should be included into E-1 and FR-Z.1.

(5)

The D.

C.

Cook plant design does not include safety related containment fan coolers that automatically start on an SI actuation signal.

Therefore, steps in E-O, ECA-0.2, ECA-l.l and FR-Z.l should be modified to delete the emergency fan coolers.

6924S/042586 28

APPENDIX A COMPARISON OF SYSTEM DESIGNS FOOTNOTES:

(Cont.)

(6)

The pr1mary function of the a1r rec1rculation/hydrogen skirmer system is to assure containment pressure reduction after blowdown.

This is accomplished by continuously circulating air from the upper to the lower compartment immediately after blowdown.

The secondary function of this system is to prevent the unlikely accumulation of hydrogen in pocketed areas within the containment resulting from a LOCA.

The air recirculation fans are automatically started by a Phase 8 signal after a

10 minute delay.

The air recirculation/hydrogen skimer system should be included in E-O, FR-Z.l and ECA-0.2.

(7)

The Distributed Ignition System ("hydrogen ignitors") is designed to provide additional hydrogen control capability in the unlikely event of a severe degraded core cooling event involving the generation of substantive amounts of hydrogen.

The Distributed Ignition System should be considered for inclusion in E-l, FR-C.l, FR-C.2, FR-Z.1, FR-H.l, FR-I.3, ECA-O.O and ECA-0.2.

(8)

Main steamline bypass valve operation outside the control room may be an impact and should be evaluated.

(9)

Feedwater flow control bypass valves are not included in the D.

C.

Cook plant design.

Therefore, steps in E-O, FR-H.2 and FR-H.3 should be mod1fied to delete the feedwater flow control bypass valves.

Low head SI pumps de11ver to 4 hot legs The containment spray heat exchangers are utilized, if needed, during the reci rculat1on phase.

Therefore, cooling water to the containment spray heat exchangers is required during the rec1rculat1on phase of a LOCA, when containment spray is required.

ES-1.3, ECA-1.1 and FR-Z.l should be written to include this design feature.

The D.

C.

Cook design has spray capability using the RHR pumps.

RHR spray should be initiated if the containment pressure exceeds 8 psig following the initial blowdown.

Also, RHR spray should not be used until the accident has progressed to the point when ECCS is 1n the recirculation

phase, or at least 30 minutes after the accident.

RHR spray is 1n addition to the spray suppl1ed by the containment spray pumps.

The add1tion of RHR spray capability should be included into E-1 and FR-Z.l.

(10)

(12)

The D. C.

Cook plant design does not include safety related containment fan coolers that automatically start on an SI actuation signal.

Therefore, steps in E-O, ECA-0.2, ECA-l.l and FR-Z.l should be modified to delete the emergency fan coolers.

Low head SI pump suction valves from the containment rec1rculation sump do not automatically open on low RWST level.

Switchover is manually in1tiated after stopping the low head SI pumps..

(13)

The primary funct1on of the atr rec1rculation/hydrogen skineer system 1s to assure containment pressure reduction after blowdown.

This is accomplished by continuously circulating air from the upper to the lower compartment immediately after blowdown.

The secondary function of this system 1s to prevent the unl1kely accumulation of hydrogen in pocketed areas within the containment following a LOCA.

The air recirculat1on fans are automatically started by a phase 8 signal after a 10 minute delay.

The air recirculation/hydrogen skioeer system should be included in E-O, FR-Z.l and ECA-0.2.

(14)

The Distributed Ignition System (hydrogen tgnitors) 1s designed to provide additional, hydrogen control capab111ty in the unlikely event of a severe degraded core cooling event 1nvolving the generation of substantive amounts of hydrogen.

The D1stributed Ignition System should be considered for inclusion 1n E-l, FR-C.l, FR-C.2, FR-Z.l, FR-H.l FR-1.3, ECA-O.O and ECA-0.2.

COOK EOP STEP DOCUMENTATION FORM INTRODUCTION The EOP step. documentation form was developed for the purpose of documenting the technical differences between the WOG ERGs and the D.

C.

Cook EOPs as described in Part 5.3 of the Plant Specific Technical Guidelines.

Recorded on these forms are the technical differences, and the explanations or bases for them.

The documentation forms are compiled in order of procedure

number, and can be used effectively with the following information:

1)

When the're are technical differences between a given EOP and its corresponding ERG, the EOP step number will be listed in the left column of the form.

The step number of the respective ERG step will be listed in the center

column, and the explanation or basis of the difference will be given in the right column.

2)

A copy of the ERGs and EOPs must be used in conjunction with step documentation forms as a step text is not presented on the forms.

3)

For EOP steps not listed on the forms, there are no technical differences from the ERG steps.

Therefore, no explanation or bases are needed.
