Purpose To establish a method of identifying raw- material stock in terms of basic composition and thermal condition

Scope This procedure applies to raw metallic material that is to be used for production purposes in the Fabrication Department Specifically excluded are castings and extrusions or any other material that is produced in accordance with engineering drawings and is assigned a part number distinctly different from commercial part numbers

11- A. l Identification System

The identification system used may be expanded to provide for materials that may be added to the listings (Table 11-A.2) by assigning striped colors, which are avail­able within the system, or, if necessary, by using more than a single stripe.

11- A.2 System Description

All metals shall be identified by a color-coding system that uses the twelve basic colors listed in Table 11-A 1 A combination of at least two of these colors is required to identify a stocked item The use of the colors shall be according to the system described in the following para­graphs

(a) Body Color. One of the basic colors is assigned to each of the categories of materials given in Table 11-A 1

Table 11-A 1—Basic Body Colors Color Material category Red Aluminum alloys Blue Magnesium alloys Pink Brasses Yellow Beryllium coppers Orange Bronzes Green Carbon and free-cutting steels Light green Spring steels Aquamarine Alloy steels Brown Stainless steels Gray Magnetic metals Black Cast irons (bars and rods) White Coppers

This identifies the materials as falling within a specific category This color will be the background color or body color over which a stripe will be applied to identify the material according to the categories listed in Table 11-A 2

(b) Body-Color Application

1 Air-dry lacquer shall be used as the body color The colors shall match the stripe tape described below.

2 One end of bars, rods, and shapes shall be painted the body color (see Fig 11-A 1)

3 Sheet and strip and plate stock shall be stacked with one end in the same plane and the entire end painted with the body color

4 Coiled strip, wire, or tubing may be identified per item 3 above by a metal tag painted the body color and attached with a length of wire to the coil [Fig 11-A 1(c)]

(c) Stripe Color Strips of colored pressure-sensitive vinyl tape V8 in wide shall be pressed across the body color painted on the ends of tags, bars, rods, or shapes Painted stripe is used on sheet stock Within any category of Table 11-A 1, the body color shall not be used for a stripe

(d) Stripe Application.

1 The striping tape shall be applied across the center of the body-colored ends of bars, rods, and shapes, except in cases where the diameter is so small or the configuration such that the body color is not clearly evident after the application, then the tape shall be wrapped around the material close to the painted end.

2 Stripes shall be painted over the body color on the ends of sheet, plate, or strip The stripes shall be placed so that when material is cut off a sheet, the color-code identification is not lost

3 Stripes shall be painted on coils of strip, wire, or tubing, or tape shall be applied across metal tags

with boron carbide powder. The 80 control rods enter tne reactor through thimbles in the bottom of the pressure vessel and enter the bottom of the core through holes in the core support plate. A tube for each control rod extends upward from the bottom of the vessel to the bottom core support plate to guide the rods in this region. Each rod is equipped with its own drive mechanism located within the pressure-vessel thimble and operating in the reactor pressure environment.

In most other reactors using vertical control-rod motion, upward rod movement increases the core reactivity by moving the poison section out of and above the core. The Dresden reactor, however, has its control rods fully in
