C. Manufacturing Facility
The manufacturing facility is of a new and unique design and is planned specifically to produce the standard Floating Nuclear Plants. An artist's concept of the completed facility on Blount Island as it will appear in a mature state is shown on Figure 5.
The facility is subdivided into three major areas: 1) production shops to manufacture and assemble components and subassemblies; 2) the construction slip for final assembly of the plant; and 3) outfitting and testing area. Support facilities, utilities, and facilities maintenance are provided throughout the manufacturing facility as necessary.
The production shops are designed so that raw material enters at one end and finished products exit at the other. Their location relative to the overall layout will permit finished products to be easily transported to the construction slip. Major production efforts include the following shops :
Nuclear Component Shop.—Piping elbows will be added to the steam generator and pump volutes, the reactor vessel internals will be fitted to the vessel, and the control rod drive mechanisms will be assembled and welded to the vessel head. Additionally, the reactor vessel, steam generators, and certain other vessels will be thermally insulated prior to installation in the plant. Major nuclear components, prepared for installation on the platform in this shop, weigh from 100 to 500 tons and require special handling by the large gantry cranes serving the construction slip.
Steel Fabrication Shop.-Functions of the steel fabrication shop complex will include receiving, handling, shot-blasting, cutting, and forming steel for the platform and plant superstructure. This complex also encompasses assembly and welding of structural webs, structural hull panels, foundations, and miscellaneous structural elements such as ladders and temporary attach: ments. Material handling and machine loading will be mechanized as far as possible. A tank shop will be included for the manufacture of large tanks required for the plant. This shop will operate under the jurisdiction of the ASME code "N” stamp.
All mild steel assemblies will require touch-up blasting and final coating prior to erection aboard the plant. This will be accomplished in a semiautomated blast and paint facility.
Concrete Shop.- The concrete shop will manufacture and precast concrete; fabricate and assemble forms, and fabricate reinforcing steel assemblies to be used for structural concrete or biological shielding.
Concrete mixed in the batch plant will be pumped to the appropriate location in the slip or to the precasting area. Both precast and form-reinforcement assemblies will be positioned along the slip using rubber-tired transporters and will be lifted in place by a gantry or whirler crane.
Condenser Shop.-The turbine condensers will be assembled and tested in the condenser shop. The in-stop transportation system of dollies and rails will extend beneath the large gantry cranes to facilitate moving the completed condensers aboard the platform.
Sheet Metal Shop.–Ventilation ductwork, fittings, dampers, louvres, benches, counters, firestops, constructural walls, angle and formed steel foundations, some HVAC units, fan, cooler and filter units, and other components manufactured from sheet steel will be fabricated in the sheet metal shop. Components and structural members of the containment ice condenser will also be built in this shop.
Electrical Shop.—The electrical shop will manufacture the Rod Control Room and the Process/Control Room. These assemblies will be completely modular, will be outfitted with the rod control electronics, process racks, main display panels control console, computer, and HVAC units. These units will be prewired and checked prior to installation.
Other products and services from this shop will include: cables cut and fitted to predetermined lengths and configurations for installation aboard the platform; and the assembly, checkout, and calibration of panels, electrical gear, and instrumentation. Final rechecks will be made on switchgear, motor control centers, circuit breakers, and related electrical components.
Pipe Shop.-- From purchased lengths of pipe and fittings, the pipe will be cut, beveled, cleaned, bent, welded, and completely fabricated into pipe assemblies for installation on the plant. The pipe shop will operate under the jurisdiction of the ASME code “NA” stamp.
Assembly Platens and Staging Areas.-Assembly platens and staging areas are located throughout the facility, particularly near the dry dock, to act as buffer and storage zones and to permit erection of very large, heavy modules for installation into the platform structure or onto the plant. These areas give a smooth flow to materials handling functions and allow rapid adjustment of erection schedules without interference with shop production schedules.
Plant erection will be completed in à 450-foot-wide graving dock and wet slip. As a new platform structure is completed and launched from the graying dock, each plant in the slip advances one position. Erection functions to be performed at each stage of the wet slip are designed and scheduled to minimize dealys due to each plant move as well as to provide the optimum in material handling functions.
There is adequate deep water clearance to maneuver one plant around another moored at the seawall. Since final outfitting and test services will be equally available, a plant may be stationed at any vacant seawall slot and remain there until ready for towing to the Owner's site. An additional mooring area will be available along the seawall as an emergency hold position in the event a unit cannot be immediately towned to its site.
All major erection activities and heavy installations will be completed while the plant is in the wet slip. Crane service is provided by large gantry cranes with lift capacities greater than that required for the heaviest plant components. Whirler cranes will supplement and pass beneath the gantry crane. In addition, a large laydown area will be available on each side of the slip under the gantry crane.
As erection nears completion, the plant will move out of the wet slip and be moored at the final outfit and test area. This area will basically be an admin. istrative center, and will be centrally located to service several positions along the waterfront. These positions will provide an unhampered flow of circulating water, shore steam, condensate, and electrical power during all phases of functional testing. After final outfitting and the satsfactory completion of the functional testing, the plant will be prepared for tow to the site.
Material receipt and storage areas will be strategically located throughout the facility. A central office building will house most administrative and engi. neering operations, while yard operations administration and facilities engineering will be housed in another building. A clinic and a training center will service the entire work force; safety and security will be housed in a plant protection center; a large shop will supply general yard maintenance; and a garage will be available for mobile equipment maintenance. All support facilities will be conventionally equipped and sized according to estimates of the work force and their activity level.
The facility has unusually high demands for electric power and demineralized water, as well as all the customary shipbuilding quirements. Steam, compressed air, oxygen, nitrogen, and demineralized water will all be produced on site and distributed underground. Other utilities will be purchased in bulk, stores, and distributed as required. Main distribution lines will be housed in tunnels, flanking and parallel to the erection slip. Supply lines to the shops and slip will run transversely off of these mains.

STATEMENT OF EDWARD R. EBERLE, CHAIRMAN OF THE BOARD
in New Jersey.
Here with me are John Betz and John MacDonald, vice presidents of the company, Fred Snyder, manager of engineering, and Mr.
Kehnemui, who is the plant manager for our Atlantic nuclear plant.
Now I am appearing here today to present my company's views on the environmental aspects of locating nuclear powerplants offshore as these thoughts may relate to the proposed Offshore Marine Environmental Protection Act of 1973 which your committee presently has under consideration. I plan to confine my remarks specifically to the ocean siting of nuclear powerplants as requested by your committee.
We have a booklet, the Atlantic Generating Station, which we would like incorporated in the record.
Senator HOLLINGS. Fine.
For millions of years the immense potential of the oceans to serve mankind has been only minutely utilized. Until now the oceans have been used for transportation, food and pleasure. Now, the constantly increasing demand for energy has led electric utility companies in New Jersey to the sea, and into one of mankind's great technological steps forward. The oceans, with their inexhaustible supply of water, can readily provide the cooling that is so vitally necessary to today's modern nuclear energy plants. They will do this important job without affecting the great resources of marine biology of the deep. The
purpose of this booklet is to provide answers to some of the questions we think may be foremost in the minds of New Jersey residents regarding this unique approach to meeting the energy needs of the State.
