The obj ective of this concept is to establish a cleal and continuing responsibility and accountability for the performance of B6W plants (both operating and nonoperating) in response to those transients (both normal and abnormal) which are within the design basis of the plant.

The performance engineering responsibility will be assumed by the unit whien has the responsibility for the system analysis of the particular transient under the present organi:ational arrangement. For exa=ple, Safety Analysis will be responsible for performance of B6W plants and response to secondary loss of coolant accidents '(steam line breaks,etc.), and ECCS Unit will be responsible for the overall performance of B6h' plants and response to primary loss of coolant accidents.

The responsibility will include both the engineering and administrative i,nterface functions necessary to assure that all plants on a continuing basis meet contract and licensing requirements, as well as the requirement of an excellent engineered product in response to the transients assigned.

In its performance engineering function the unit will be responsible to assure that written functional requirements, based on thorough plant level engineering, are issued to the responsible system group for each plant system whose function is relevant to the overall plant performance for the transient of concern. This includes not only functional requirement in specific engineering terms for systems which must act, but also interfacing functional requirements for systems which must not act. These requirements are to be contained in functional specifications which will be control documents owned by the Performance Engineer. These requirements will inelide reliability goals, where appropriate, to assure that failure limits are met.

It will be the responsibility of the designated Systems Engineers to assemble a total set of functional requirer.ents for his system, and incorporate

~

these into a system description along with a design which meets them.

It will be functional Performnce Engineer's responsibility to assure by follow-up that his requirements have been properly understood and incorporated for each system. It will be his further responsibility to assure that ability to meet essential performance assu ptions is demonstrated by one of the following three methods:

a. Specific testing,

b. Plant experience, and

c. Reviewed engineering analysis.

The Performance Engineering unit w'ill be responsible for specifying the function of the operator in meeting the performanc.: goa . This will be accomplished by assuming direct responsibility for engineering input to operating guidelines consisting of event trees, description of operational strategy of objectives, and description of expected system behavior for the transient. This input will be combined by a counterpart engineer within the Nuclear Service Department with a procedural outline to make a complete operating guideline. The responsible Performance Engineer will review the co=plete guideline for correctness and completeness and will approve it by'his signature.

Performance Engineer will have the responsibility to evaluate the transients which occur in operating plants which are similar to or identical to the transient for which he is responsible and to assure, as a result of his evaluation, that his design basis and operating basis, as contained in the operating guidelines, is correct and is being correctly implemented.

hnere corrective action to the performance design basis and/or to the operating guidelines is indicated, the Performance Engineer shall be responsible for initiating and carrying such action through to completion.

EUO.26.}

• s.

The position of the Performance Engineer for specific transients shall be staffed in each unit on a continuing basis with individuals who have the requisite technical knowledge of the performance area and the analytical methodology to perform the functions that are outlined above. This will include a knowledge of the requirements for the particular transient of concern and a knowledge of the overall plant and its performance, including a knowledge of plant systems and thei boundaries. The incumbents in these positions will have personal qualifications, including assertiveness, ability to work with people to accomplish required actions quickly, along with good written and oral communication skills. These individuals,will be called upon on a continuing basis to evaluate plant performance from field operating experience and to participate in the training of operators.
