February 1979 The scope of the review directed by this plan will include descriptions of the quantity of water required for plant operation, the amount of water consumed by the plant water systems, and the amount of water discharged to a water body.
Variations in water requirements and consumption on a temporal basis and as a function of plant operating modes will be included.
Where water use for station operation is greater than plant water use, these uses will also be included.
The review will be in sufficient detail to provide basic data for other reviews dealing with the evaluation of plant operational impacts.
II.
REQUIRED DATA AND INFORMATION The kinds of data and information required will be affected by site-and Station-specific factors, and the degree of detail will be modified according to the anticipated magnitude of the potential impacts.
The data required will be in sufficient detail to trace the flow of water from the water supply sources to the points of discharge, indicating quantities consumed at each point of consumption as a fune. tion of plant operating conditions. The following data and information will usually be required:
A.
A narrative description of the various plant water systems, their interconnections, and their operational interdependence and coordination (from the ER).
B.
A water-use diagram for the plant showing flow rates to and f rom the variots water systems (e.g., circulating water system, sanitary systen, radwaste and chemical waste systems, service water systems), points of consumption, ano source and discharge locations (from the ER).
)h 3.3.1-2
February 1979 C.
For the water-use diagram required (above), the data and narrative description for maximum water consumption, water consumption during periods of minimum water availability, and average operation by month (from the ER).
D.
A description of other station water uses (i.e., all facilities not associated with the proposed plant) showing flow rates to and from the facility, average water consumption, and maximum water consumption (from the ER).
II..
ANALYSIS PROCEDURE The reviewer's analysis will be closely linesed with the reviews described by ESRPs 3.3.2, 3.4.1, 3.5, 3.6, 5.2, and 5.3 in order to establish the plant water-use characteristics of concern to those reviews.
The reviewer will analyze flow diagrams of plant water systems by perform-ing simple mass balance computations to ascertain whether the reported flow rates (water source withdrawals, different plant water system needs, and discharge flows) are consistent for each plant operating mode.
Those condi-tions considered should include periods of maximum water consumption, minimum water availability, and average operation by month. The reviewer will determine if there are other station facilities with water uses not associated with operation of the proposed plant and will include these uses in the analysis.
ES Section 3.3.1 is intended to give a brief descri;. ion of the water use in plant systems and the principal subsystems.
Details of the principal subsystems are described in ES Sections 3.4.2, Cooling System C?mponent Descrip-tions; 3.5, Radioactive-Waste-Management-Systems; and 3.6, Nonredivactive Waste Systems.
Therefore, the reviewer of ES Section 3.3.1 will concentrate en the description of principal flow paths f rom the sources of water through each subsystem to the receiving water bodies without detailed flow patterns within each subsystem.

EVALUATION The reviewer will ensure that the water-use information is adequate to describe plant water requirements and other station water requirements, to serve as a basis for assessing the sufficiency of water supply, and to assess the impacts of plant operation.
V.
INPUT TO THE ENVIRONMENTAL STATEMENT The follow),g information will usually be includea in E5 Section 3. 3.1:
A.
Jescription of the flow path of water fron the water sources through each major pir.ro water system (e.g., teat dissipation systen,,anitary system, radwaste and chemical waste systems, service water systas) the points of discharge, including consumption for each such path (e.g.,
cooling tower evaporation).
O B.
flow diagram to assist in tracing the 'los path and the *'ates of
^
flow for nnimu" water consumption, water ccr.su*ption during periods of minimum water avai1 ability, and average operation t;y no n r *.
Detii13 of seasonal and other operating variations rray be provided in narrativo ar.d tabul ar f orms.
C.
As appropriate, descriptions of other sta ti on water regt'i renent s.

Sections 5.2 and 5.3.
The reviewer will provide plant or station water-use data requirements to the reviewers of ES Sections 5.2 and 5.3 in sufficient detail to support the assessments given those sections.
D.
Section 9.
The reviewer will provide plant water consumption data to the reviewers of ES Section 9 as required for their analyses and evaluations of plant or component alternatives.
