VEHICLES

A. INTRODUCTION

Paragraphs

73.3 1(b) and 73.33(a) of 10 CFR Part 73, "Physical Protection of Plants and Materials," require that road or rail vehicles transporting special nuclear material in quantities identified in paragraph

73.1(b)(2)

be equipped with a radiotelephone in order that com munication between the transport vehicle and a respons ible licensee can be maintained.

Paragraph

73.70(g) of 10 CFR Part 73 requires that certain information with regard to the shipment be recorded prior to the shipment.

This includes the name of the carriers, major roads to be used, verification of communication equip ment on board the transfer vehicle, names of individuals who are to communicate with the transport vehicle, and other information needed to comply with §§73.30 through 73.36 of 10 CFR Part 73. This guide describes radiotelephone equipment and systems, and procedures for their use, that are acceptable to the NRC staff for complying with the Commission's regulations regarding radiotelephone communication in connection with road or rail shipments of special nuclear material.

This revision reflects comments received from the public and other factors.channels, which are individual circuits around a par ticular carrier frequency, for each system are shown in Table I. TABLE I NUMBER OF CHANNELS PER CARRIER Bell RCC (35,43) (152, 158) (454,459)

B. DISCUSSION

Available Systems There are two radiotelephone systems that have a sufficient number of transmitter/receiver stations throughout the country to allow the placement of long distance calls. These are the Bell System Mobile Tele phone system and the Radio Common Carrier system (RCC). The Bell system uses three different carrier frequencies

[(35, 43), (152, 158), and (454, 459) MHz], and the RCC uses two different carriers [(152, 158) and (454, 459) MHz]. The vehicle receives long distance calls on the lower carrier frequency in each group, i.e., 35, 152, and 454 MHz, and transmits on the higher frequencies, i.e., 43, 158, and 459 MHz.

Application for equipment rental or telephone service could be made to a local Bell or RCC system company where a licensee or carrier would have most need of the service.

If purchased equipment is to be operated on the Bell System, a license will be required from the Federal Communications Commission (FCC). Purchased equip ment operating on the RCC system may not require an FCC license. Maintenance of the equipment is provided when it is leased from the Bell or RCC systems.

Purchased equipment must be serviced by licensed operators, as required by FCC regulation

47 CFR 21.207(e), "Transmitter Measurements." There are several categories that define the priority for obtaining service. These are described in FCC regulation

47 CFR 21.512, "Priorities for service to subscribers." System Aspects There are several types of service and equipment that can be obtained.

The service available is dependent on the area. The equipment that can be ordered depends on whether local or nationwide service is desired. In general, the types of service available are: 1. Manual service with access to an operator.

2. Two-way dial with automatic channel selection and access to an operator (also known as Improved Mobile Telephone Service, IMTS). 3. Two-way dial service with access to an operator.

4. Two-way dial service without access to an operator.

The most inclusive service afforded is that of two-way dial with automatic channel selection and access to an operator (IMTS). This service is available on the (152, 158) MHz and (454, 459) MHz carriers only. There are at least two varieties of radiotelephone equipment that can be applied to this service. In one type of radiotelephone operating on the (152, 158) MHz carrier, all eleven channels in the United States are available through the selection of pushbuttons on the telephone.

Additionally, three other pushbuttons, Home, Roam, and Manual, -are available.

When a vehicle is in the Home area, the Home pushbutton is depressed and the Home area channels will be selected auto matically.

When a vehicle is outside the Home area, the channels for the particular area must be selected by depressing the channel pushbuttons, as well as the Roam button. The radiotelephone will now automatically select available channels in that area. Another type of radiotelephone operates on the (454. 459) MHz carrier and can automatically select channels in a local area only; it does not have a feature that permits selection of other channels, but could operate in another area on an IMTS mode if the channels were the same as in the Home area. Other variations in the available equipment are nondialable phones (used only for manual service) and simplex or duplex operation.

Simplex operation means that the telephone cannot transmit and receive informa tion simultaneously.

That is, while a person talks, he will not be able to hear a response from the other party. To hear the other party, he must stop talking and release a button on the telephone.

Duplex operation allows the transmission and receipt of information simultaneously as in normal telephone service.

Preplanning Radiotelephone call-in times can be preplanned in advance of the shipment by using a booklet issued by the American Telephone and Telegraph Co. entitled "National Mobile Telephone Service Area Listing" or a booklet issued by the Radio Common Carrier entitled "Nationwide -Service Directory" in conjunction with the route maps to be used with the shipment.

The area covered by each base station can be put on the route maps and radiotelephone call-in times not to exceed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> determined.

When a radiotelephone call cannot be planned to occur within a 2-hour period, conventional telephone call-in location and time should be deter mined. This can initially be determined by locating cities, towns, or populated commercial areas along the route. The conventional call can be preplanned to occur at an approximate time (planned not to exceed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />) from one of these areas. As experience is gained with particular routes, conventional telephone calls can be planned with greater precision.

The drivers can note specific telephones or areas where telephones are avail able along the route for future conventional telephone call-in planning.

Communication Procedures A radiotelephone conversation can be overheard by anyone having a radiotelephone set with the same carrier frequency and channels.

It is therefore necessary to disguise the position of the shipment and the routes to be taken. One method for accomplishing this is the use of a transparent nonfoldable grid overlay on a standard road atlas. This grid can consist of one-half-inch squares with the horizontal axis labeled with letters and the vertical axis labeled with numbers. A typical overlay is shown ir Figure I and is about 10.5 inches by 14 inches in overall dimensions.

The road atlas chosen should have a scale of one inch equals 3 miles or less. The resolution of a one-half-inch square on the overlay would then be about 1.5 miles. With a scale of one inch equals 3 miles, it may be necessary to use several roadmaps to cover a shipment.5.32-2 A B C D E F G H I J K L M N 0 P Q R S T U 2 3 4 5 6 7 8 9 10 I I 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Figure 1. Overlay with 1/2-inch grid (not to scale)5.32-3 A typical procedure that could be followed under these conditions is as follows: 1. Each map is assigned a number. 2. In order to position the grid with respect to the map, reference points are selected on the map. The grid is placed over the map, and distinct intersections or other identifiable landmarks are selected and given grid coor dinates. These should be placed directly on the map as shown in Figure 2 with a relatively fine black marker type pen. 3. The driver could use the following procedure to telephone his position:

a. Select the map which includes his position.

b. Locate his position between two reference points on the map and place the appropriate coordinates over the reference points. Telephone the position as map number, reference points, and actual coordinates.

4. Duplicate sets of maps should be made by the licensee or his agent prior to the shipment;

copies should be given only to the drivers and escorts (when they are used) and the individuals responsible for maintaining telephone cormmunication with the shipment.

Another method that can be used to disguise the position of the shipment is known as the "checkpoint" system. This approach, applicable to preplanned routes, uses landmarks as checkpoints.

The landmarks are typically all towns, cities, villages, state lines, and major highway intersections along the preplanned route. The landmarks are identified by a symbol (number or alphabetical character)

on a single strip map carried along with the shipment.

The driver, in reporting his position, relates only the symbol applicable to his position, or "x" number of miles from a landmark.

Mileages between landmarks and those locations where commercial telephones are available on the strip maps may also be included.

Personnel controlling the ship ment should have a corresponding strip map and plot the progress and locations of the shipment.

A third method of disguising the movement of a shipment is through the use of a telephone voice scrambler.

This device, when placed in front of a telephone, will "scramble" the message over the com munication link and will produce unintelligible sounds at the other end of the circuit unless a companion device that is matched to the sending device is also available in front of the telephone at the other end. Telephone voice scramblers are therefore available in coded pairs and can be made available in matched sets of more than two units to handle conference calls or calls from a vehicle to different locations.

C. REGULATORY

POSITION 1. Systems Aspects The system that provides the most radiotelephone coverage along the route of the shipment should be selected.

After a system has been selected (i.e., Bell or RCC) the radiotelephone selected should have all avail able channels for the carrier chosen. As a minimum, the telephone should have, where available, two-way dial service with access to an operator.

2. Preplanning The licensee should preplan the shipment route if he is going to make the shipment;

otherwise, he should obtain a preplanned route from the carrier. Routes should be preplanned to use as much radiotelephone coverage as possible.

The requirement that transit times be minimized (paragraph

73.30(b))

should be observed;

however, making radiotelephone calls is the more desir able feature, and transit times could be somewhat increased to accommodate good radiotelephone cover age. Since all radiotelephone stations may not accept calls from a number that is not in the local directory, calls to each radiotelephone area selected should be made to ensure that the operators will accept outside calls. Where radiotelephone coverage is not available without extensive rerouting and where conventional telephones are available along the route, conventional telephone calls every two hours should be preplanned.

The licensee or agent responsible for communi cations liaison with the shipment should be predesig nated before a shipment is made. A continuously manned telephone with an unlisted number should be provided at the licensee's or agent's facility.

This telephone should not be used for any other calls while a shipment is in progress.

Appropriate local law enforcement authorities (LLEA) such as the Head of the State Police, the State Safety Director, or the local State police barracks.

should be contacted in advance of a shipment to ensure that recovery procedures will be followed and that adequate response forces will be available along the route. Once initial contact has been made. it is not necessary to reestablish contact for subsequent ship ments through the same jurisdiction except that pro cedures should be reaffirmed at least annually.

The telephone number of the LLEA along the preplanned route of the shipment who will be called in case of an emergency or failure of the transport vehicle to call in should be given to the vehicle crew and the persons responsible for maintaining communications with the vehicle crew. 3. Communication Procedures The checkpoint or voice scrambler is preferred to the grid method for concealing the position of a vehicle.

The grid may offer some operational problem in a *Lines indicate substantive changes from previous issue.5.32-4'*N

moving vehicle. All three methods, however, are consia ered acceptable for concealing the position of a vehicle.

When a scrambler is used, some method of obtaining an accuracy equivalent to that of the grid or checkpoint system should be developed.

Maps containing the routes to be used as part of the grid or checkpoint systems should be assembled and distributed to the vehicle crew and to individuals who will be responsible for main taining codmmunication with the shipment.

The vehicle crew should update their position at least every fifteen minutes so they could communicate their location in case of emergency.

Procedures for obtaining telephone channels when all are busy and an emergency exists should be understood and practiced by the vehicle crew. In cases where a radiotelephone call has been planned and cannot be made because of overcrowded channels, atmospheric interference, or other reason, the vehicle personnel should continue attempts to complete the radiotelephone call and should also plan to make a conventional telephone call as soon as possible.

The licensee monitoring call-ins should contact the LLEA where the vehicle is last reported, the LLEA where the vehicle is supposed to be, and all intermediate LLEAs within 30 minutes after the scheduled call-in time if communications with the vehicle have not been estab lished. The NRC regional office of the licensee monitoring communications and the NRC regional office for the region in which the vehicle was last reported should also be notified.

D. IMPLEMENTATION

The purpose of this section is to provide informa tion to applicants and licensees regarding the NRC staffs plans for utilizing this regulatory guide. This guide reflects current regulatory practice.

Therefore, except in those cases in which the applicant proposes an acceptable alternative method for comply ing with specified portions of the Commission's regula tions, this guide will be used by the staff in evaluating the materials and plant protection portion of license applications, licensee security plans, or other documents pertaining to materials and plant protection submitted to the NRC on or after the issuance date of this guide.5.32-6 UNITED STATES NUCLEAR REGULATORY
