Those on distribution who_se. names are asterisked, plus myself, attended a me eting on July 27, 1979, to establish preliminary ccncepts for generation and maintenance of E=crgency Operating Guidelines. The attached flow chart and words were agreed to conceptually, although polishing is needed before either document reaches final for=.

It was decided to make this docu=ent specific for operating plants te=porarily.

I expect to present a s4-41ar document for startup plants and the backlog in the future, af ter so=e discussion with Project Management.

One specific issue was raised which needs to be addressed further. The attendees felt that the only approvals needed for the Energency Operating Guidelines were Plant Design, Plant Perfor=ance, and Training. Historically, Operating Plant Services has had final signoff on all documentation sent to operating plants.

l By oversight, Operating Plant Services was not invited to this meeting and so as yet have had no input to this procedure, although a copy of the flow chart was provided to Ken Ellisen prior to the meeting. I request that Ken Ellison I provide to =e, in writing, his thoughts on the advant' ages and disadvantages of deleting the Operating Plant Services signature requirements on the Emergency Operating Guidelines.

Also c=itted was a valk-through of the proposed guidelines at the customer's facilities with B&W in attendance; this step was suggested by Allen Wo=ack.

The inputs utilized by Plant Perfor=ance Services and Plant Design were left for later definition, perhaps in another procedure. Our custo=ers have requested a proposal for Licensing Event Report review, which would provide some input to the procedure. Also specified in the first writeup was a reviev of Su==ary Test Reports, Site Problem Reports, and detailed data on each transient which occurs-at B&W plants. Also to be reviewed were analyses conducted on future plants.

k). F. Hall =an to Distribution July 30, 1979 - Page Two E=ergency Operating Guidelines Preparation & Maintenance I feel the LER proposal should be incorporated somehow into an E=ergency Operati @

Guideline proposal, and inputs to be examined should be clearly specified. How-E ever, the inputs specification may define B&W's legal liability'in maintaining th'e Emergency Operating Guidelines and should be given careful thought.

Those on distribution are requested to provide comments to me, in writing, on those issues specified above and also on the attach =ents. I would appreciate these con:ments by August 7,1979.

Emergency Operating Guideline (Operating Plants) 1.0 Purpose QOEuM:K.

D

(

The purpose of this procedure is to establish the Emergency Operating 7' i

Guideline as the method utilized b'y B&W to advise B&W NSS operating plants the proper method to operate B&W NSS' during abnormal / upset conditions.

2.0 E=ergency Operatine Guideline Content The Operating Gu'idel~ine will consist of two basic p~ arts. Part_,I will._, . . .

4 provide detailed operating instructions to the . plant operators of. . .... ...

! specific sympto=s to observe and specific actions to take or not take as a result of these symptoms. Part II will give the bases for the detailed instructions in Part I and the expected plant response to the conditions covered by the guideline.

l These guidelines will be translated into plant-specific operating pro-

~~

cedures and training by the utility.

Part I will consist of the following basic sections:

i 1.0 Sy=pta=s:

Plant characteristics which can be obs erved from readily available alarms / instrumentation and which characterize the event.

(

, 2.0 lesediate Actions:

! What the operator is expected to manually perform within the first few minutes of the symptoms. .

3.0 Precautions

Limits which =ust not be exceeded to maintain plant .

safety and actions which apply throughout the event.

TOS701

n. ...

~ * * - * * * * * * '

. 4.0 Followup Actions: Specific actions to take as a result of the event and specific plant behavior subsequent to the event, but which, if not taken within the first 10 minutes or so, do not degrade plant safety, and which take the plant to a stable cooling mode (hot shut- h a

down, cold shutdown, or LPI cooling).

Part II will consist of the following two basic sections in prose adaptable to operator training programs:

5.0 Basis

What features are designed into'the plant to handle this event type and why these features are used as specified in immediate i ,

, and followup actions.

6.0 Plant Response: The expected plant response, both initially and as a result of recc= mended operator actions, during the event covered by I - the guideline.

. 3.0 Original. lssue Emergency Operating Guidelines will be devised to cover abnornal plant condic e

- tions such as small RCS breaks, steam line breaks, etc. Plant Design will i identify design features which keep the plant safe during specific events, and how they should be handled during these events. Plant Design and PPS v111 prepara event trees as needed. Plant Design will also prepare Sections 5.0 and 6.0 (previously defined) of the Operating Guidelines.

Plant Perfornance Services will take the input from Plant Design and prepare i

Sections 1.0 through 4.0 of the Operating Guideline. Plant Performance i

Services and Plant Design will interface with Training Services to consider I

TOS705

.t man-machine interfaces in preparing the detailed specification, and will .

test the new EOG on the simulator. Plant Performance Services will then prepare the final document, resolve any outstanding technical issues, i

and send to Docu=ent Composition. 7 Document Composition will type the final document, assign the Document ID' Number, and route for signoff to the following organizations:

e Manager, Training Services or designee e Manager, Plant Design or designee -

i e Manager, Plant Performance,_Seryice.s_or__ des _ignee _ ,,,__ _ _.

e

~ ~~~"

PPSS will maintain list of designacia'T pio'pl'e'Iuth%ri~

n zed Y6-sign 'and -

will assure proper signatures are obtained.

i i

After signoff, the document will be-sent to Contract Services for informa-

~

l tion and to Operating Plant Services for customer transmittal.

l 4.0 Revisiens

' Plant Performance Services and/or' Plant Design will be respon'sible for updati.

Emergency Operatibg Guidelines whenever updated information indicates that the best, safest plant control methods are not in the Guidelines, o_r when it appears instructions should be modified to allow better man-machine

! interface. To accomplish this, the two groups will continually review t

the following:

l i

! e SPR's on B&W operating plants e PWR LER's e New Regulatory requirements e Other infor=ation from customers TOS706

In addition, PPS will review restart test program STR's and PD will review analyses on new plants. Response will be per the attached flow chart.

NOTE: Per meeting July 27, it was decided to delay exact inputspecifica-h t

tion until customer' interfaces were better established.

5.0 Utility Response The utility will provide information, on all operating transients, through OPS. Continuous measurements are needed of vital paramIeters such as RCS pressure'and temperature, steam pressure, etc. at 3-second intervals or l shorter during all transients. Records of operator actions, from operator i

logs or post-transient interviews, are also needed. These will be evalu-1 j ated by PPS and FD to determine if plant and operator response were adequate, or if better methods ' exist to prevent or mitigate the effects ,

j of transients.

- The utility will also provide comments on draft guideline changes sent to them, as input for final B&W documents. ,

The utility will also provide B&W will updated copies and revisions of l,

site-specific procedures derived from B&W-supplied operator guidelines.

The utility will also provide all intert. ally-generated field changes and j

updated P&ID's on any field changes performed on B&W-supplied systems.

6.0 Training Interfaces l

' Training Services will work with Plant Perfor=ance Services and Plant Desigs to assure that Emergency Operating Guidelines contain best B&W input on man-=achine interface. Af ter Guidelines are approved internally, Training Services will codify their operator training program as needed to reflect
