schedule for the Project’s implementation.
Phase I
The alternatives analysis shall contain sufficient design consideration (e.g., equipment sizing,
quantity, and materials) to determine whether it is technically and economically feasible to
implement each alternative. The following list provides the expected alternatives, in whole or in
combination, for this evaluation.
0 Evaluation of cooling alternatives, including, but not limited to, the following:
New Cooling Towers
Modifying Existing Cooling Towers
o Upgrade Helper Cooling Towers (fans, stacks, or fill)’
o Eliminate Modular Cooling Towers
Evaporative Cooling
Inlet/Discharge Chillers
Air Spargers/Bubblers2
0 Analysis of each alternative including, but not limited to, the following:
3 Economic Cost Estimate (including the basis for the estimate)
3 Schedule Analysis
z Quantity and Size of Equipment
s Infrastructure Requirements (e.g., electrical needs)
3 Proposed location(s) considered for the alternative
3 Site Impacts (e.g., environmental, operational and maintenance)
3 Advantages and Disadvantages Relative to Other Options
0 Identify environmental impacts for each alternative3
z Wetlands Mitigation
s Biota Impingement and Entrainment Issues
0 Preparation of an Alternatives Summary Report comparing the alternatives and an on-site
presentation (to plant personnel) of the selection results.
Phase I1
The recommended alternative shall be developed into a conceptual design, which shall contain
sufficient detail to prepare a request for proposal (RFP) package for the final equipment
procurement and design. Section X of this document identifies the level of detail expected in the
conceptual design report. PEF expects that the conceptual design can be used as the stand alone
engineering design input document for the final design.
This work is NOT nuclear safety related and does not need to be completed under the Vendor’s
’ Helper Cooling Tower upgrades were evaluated previously (additional References - Bechtel Cooling Water Study).
* Bubble cooling was previously reviewed (additional References - John Cooper & Associates Engineering
Evaluation).
PEF will perform detailed review of 316(b) impacts; Vendor is not expected to coordinate any interaction with
permit agencies. PEF expects the Vendor to identify possible environmental impacts, as well as solutions, for each
alternative.
