SUBJECT: LICENSE AMENDMENT

Please find enclosed License No. 50-23276-01. You should review this license carefully j

. and be sure that you understand all conditions, if you have any questions, you may l

contact the reviewer who signed your license at (510) 975-0250.

You should note that License Condition 20. has been added to your license relative to the

maximum amount of material you may possess under the license. This licensing action

was necessary to preclude you from exceeding possession limits of materials requiring that

decommissioning financial assurance be provided. Should you determine that you require '

possession of materialin excess of 10 CFR 30.35(d) amounts, please notify us regarding ,

an amendment to your license. l

NRC expects licensees to conduct their programs with meticulous attention to detail and a

high standard of compliance. Because of the serious consequences to employees and the

public which can result from failure to comply with NRC requirements, you must conduct

your program involving radioactive materials in accordance with the conditions of your NRC

license, representations made in your license application, and NRC regulations. In

particular, note that you must:

1. Operate in accordance with NRC regulations 10 CFR Part 19, " Notices, instructions

and Reports to Workers: Inspection and Investigations," 10 CFR Part 20,

" Standards for Protection Against Radiation," and other applicable regulations.

2. Possess radioactive material only in the quantity and form indicated in your license.

3. Use radioactive material only for the purpose (s) indicated in your license.

4. Notify NRC in writing of any change in mailing address (no fee required if the

location of radioactive material remains the same).

5. Request and obtain written NRC consent before transferring your license or any

right thereunder, either voluntarily or involuntarily, directly or indirectly, through

transfer of control of your license to any person or entity. A transfer of control of

your license includes not only a total change of ownership, but also a change in the

controlling interest in your company whether it is a corporation, partnership, or

other entity. In addition, appropriate license amendments must be requested and

i

other entity. In addition, appropriate license amendments must be requested and

obtained for any other planned changes in your facility or program that are contrary

to your license or contrary to representations made in your license application, as

well as supplemental correspondence thereto, which are incorporated into your

license. A license fee may be charged for the amendraents if you are not in a fee-

exempt category.

6. Maintain in a single document decommissioning records that have been certified for

completeness and accuracy listing all the following items applicable to the license:

Onsite areas designated or formerly designated as restricted areas as defined

in 10 CFR 20.3(a)(14) or 20.1003.

Onsite areas, other than restricted areas, where radioactive materials in

quantities greater than amounts listed in Appendix C to 10 CFR

20.1001-20.2401 have been used, possessed, or stored.

Onsite areas, other than restricted areas, where spills or other unusual

occurrences involving the spread of contamination in and around the facility,

equipment, or site have occurred that required reporting pursuant to 10 CFR

30.50(b)(1) or (b)(4), including areas where subsequent cleanup procedures

have removed the contamination.

Specific locations and radionuclide contents of previous and current burial

areas within the site, excluding radioactive material with half-lives of 10 days

or less, depleted uranium used only for shielding or as penetrators in unused

munitions, or sealed sources authorized for use at temporary job sites.

Location and description of all contaminated equipment involved in licensed

operations that is to remain onsite after license termination.

7. Submit a complete renewal application with proper fee, or termination request at

least 30 days before the expiration date on your license. You will receive a

reminder notice approximately 90 days before the expiration date. Possession of

radioactive material after your license expires is a violation of NRC regulations.

8. Request termination of your license if you plan to permanently discontinue activities

involving radioactive material.

You will be periodically inspected by NRC. Failure to conduct your program in accordance

with NRC regulations, license conditions, and representations made in your license

application and supplemental correspondence with NRC will result in enforcement action

against you. This could include issuance of a notice of violation; imposition of a civil

penalty; or an order suspending, modifying, or revoking your license as specified in the

" General Statement of Policy and Procedure for NRC Enforcement Actions" (Enforcement

Policy), 60 FR 34381, June 30,1995.

Response to Telephone / Verbal conversation

D Personnel dosimetry will be used for Mr. Timothy Gibson and others as required and

requested Quarterly TLD's will be processed by TMA/Eberline, which is a NVLAP

accredited processor.

O Mr Greg Majeran is a contact person in the event of a emergency

involving a gauge but will only isolate the area and will call Mr.

Timothy Gibson.

n The Kay-Ray gauges we are utilizing are all located on piplines with no access po.;sible to

the interior of that pipline while the shutter of the given devices are open In conversation

with Ray Parsons, Kay Ray technical services, an interlock is not required

0 I have no problem with the condition of the portable gauge source not being lowered more

than 3'in test materials.

(previously NR-412-D-129-B)

SOURCE TYPE: Gamma Source Housing .

DESCRIPTION:

The 7062B and 7062BP source housings are designed to provide both mechanical

and radiation shielding characteristics. This is accomplished by use of cast

lead shielding material with stainless steel outer jacket. Prior to serial

number B6A221, the jacket was constructed of mild steel. The design of these

source housings differ only slightly from the currently approved models 7062

and 7062P. These differences involve reduction in mass and improved

structural characteristics. Both are intended to improve the ability of the

source housings to withstand potential vibration which may be encountered :

during use.

.

LABELING:

.. .

The Models 7062B and 7062BP are labeled in accordance with the requirements of

32 111. Adm. Code 330.280 (10 CFR 32.51) or 340.2030 (10 CFR 20.203)

-

.

l

DIAGRAMS:

See Attachments 1, 2, and 3. l

l

'

CONDITIONS OF NORMAL USE:

The 7062B and 7062BP source housings are designed as general purpose devices

to be used in any application where the source activity requirement does not

exceed the authorized limits of the housing. Typically, the 7062B will be

used in continuous level monitoring or belt scale applications where a

requirement for a fan-shaped beam of radiation exists. The 7062BP, with a

highly collimated point beam, will typically be used for density and point

level measurements. These source housings are designed for use in normal

industrial work environments.

PROTOTYPE TESTING:

'

1

'

A number of prototype units have been manufactured. A vibration test was

performed based on Method 201 of MIL-STD-202E. Vibration was conducted in

each of the three mutually perpendicular axis. Vibratory motion consisted of

{

cycling from 10 Hz to 55 Hz and returning to 10 Hz in one minute at a motion

,

of 0.060 inch double amplitude.

4

Inspection during and upon completion of the test revealed no evidence of

damage or deterioration as a result of the test conducted. This test exposes

i

,

the device to vibration much more severe than that expected in the intended

i application.

! -

l ,, EXTERNAL RADIATION LEVELS:

i

.)

.

With the device loaded with 129 millicuries of Cesium-137 (Cs-137), readings

'

were:

Shutter Closed: Surface -- less than 50 mr/hr

'

12 inches -- less than 5 mr/hr

Shutter Open: Surface -- less than 50 mr/hr except in beam )

12 inches -- less than 5 mr/hr except in beam {

i

OVALITY ASSURANCE AND CONTROL:

! Each unit will be manufactured to the standard Kay-Ray /Sensall quality control

procedures. These procedures include the following checks by the Kay-Ray

'

Production Department.

Conformance of material in completed device to bill-of-material

specifications. l

,

Conformance of fabrication (welding, machining and assembly) to detail

and assembly drawings of the device.

!

Conformance of proper operation of device (shutter mechanism).

Check of radiation levels when the device is loaded with a radiation

source to assure conformance of radiation levels to previously approved

isodose curves submitted to the Illinois Department of Nuclear Safety.

H. This registration sheet and the information contained within shall not

be changed without the written consent of the Illinois Department of

Nuclear Safety (IDNS).

SAFETY ANALYSIS SUMMARY:

..3

The 7062B/7062BP was approved for distribution both to specific licensees and

) general licensees in 1980 by the NRC. At that time, Kay-Ray submitted

sufficient information to provide reasonable assurance that:

The device can be safely operated by persons not having training in

-

radiological protection.

Under ordinary conditions of handling, storage and use of the device,

the byproduct material contained in the device will not be released or

inadvertently removed from the device, and it is unlikely that any

person will receive in any period of one calendar quarter a dose in

excess of 10 percent of the limits specified in the table in Section

340.1010(a), 32 111. Adm. Codes or 20.101(a), 10 CFR 20.

Under accident conditions (such as fire and explosion) associated with

handling, storage and use of the device, it is unlikely that any person

would receive an external radiation dose or dose commitment in excess of

the dose to the appropriate organ as specified in the following chart:

PART OF THE BODY

rem

Whole body; head and trunk;

active blood-forming organs;

15

gonads; or lens of eye

Hands and forearms; feet and

ankles; localized areas of skin

Re: License Amendment Request

Dear Ms Prange:

On September 4 of this year Kennecott Greens Creek Mining Co. contracted with TN

Technologies to perform an audit of our gauges, records and radiation protection programs.

Mr. Ralph S.11 eyer, TN's manager of regulatory affairs came from Texas to do that work.

The results of that audit are as follows:

1. (NRC) Radioactive Materials License # 50-23276-01, expiration date 3-31-98.

This document was found in order. Ilowever some amendments are needed..

i

2 Radiation Safety Procedures, submitted w/ January 22,1993 renewal, were appropriate, i

llowever, changes to Title 10 CFR Part 20," Standards for Protection Against Radiation"

having taken effect in January 1994, some procedures may need to be modified.

3. Inventory, required every 6 months, records were located and placed in file for l

inspection and review. A modified device inventory check list was advised and adopted.

4. Leak tests were performed as required. Records are in order.

Kennecott is on TN's Leak Test service.

TN Technologies, Technical Services Group

PO Box 800

Round Rock , Texas 78680 512-388-9303

5. Survey Meter Calibration and Certification Records. Our Ludlum Model 3 w/ Model 447

Probe is cmrent on its annual calibration frequency.

6. Safety procedures were reviewed and the following recommendations were indicated.

j

.

4

Procedures for emergency, device inventory and inspection, contractor / vendor services,

employee information be more fully developed.

7. RSO training was reviewed and found to be appropriate.

See enclosed description of training.

8. Proposed use of a CPN density / moisture gauge would require both an ammendment

to the license and personnel training before taking delivery for the same.

(KGCMC has been approached by Toxler Electronic as an alternate to the CPN gauge)

Kennecott Grc : Creek Mining Company possesses the following generally licensed gauges

All areas were surveyed and the highest reading at 30 cm was 2.8 mR/hr. Since these areas do

not exceed 5 mR/hr at 30cm they do not pose a radiation hazard and don't need to be posted as

such.

The following procedures will be incorporated in support of and part of Kennecott Greens Creek

Mining Company's radiation safety manual and radiation safety program.

.

-

Kennecott Greens Creek employees will be instructed that only individuals specifically licensed

can install, remove, relocate and perform surveys of devices and that there is no access to the

beam area as long as the gauge is instelled. Any activity presenting potential for access to the

beam area is addressed in the lock-out/ lag-out procedure.

Leak tests will be performed by the licensee or other supplier authorized to provide such service

by the USNRC. In the event of 0.005 microcuries or more of removable contamination, the

gauge will be removed from service. The original supplier will be notified and technical

assistance to repair or dispose of the device will be obtained from the supplier. A report will be

filed with the NRC within 5 days as required.

,

Kennecott Greens Creek will conduct physical inventories of the devices every 6 months. At that

time, each device will be visually inspected to signs of damage, that tags are clean and legible,

and ensure proper shutter operation. The Device Inventory andInspection chart will be used as a

checklist. :

Alara Position and Policy Statement:

Kennecott Greens Creek Mining Company has a strong and firm written commitment to all on-

site personnel to institute safe working practices which will prevent unauthorized use or

l

unnecessary radiation exposure.

Kennecott Greens Creek Mining Company willmake every effort and shalluse to the extentpracticable,

procedures, and engineering controls based on sound radiation protection principles to achieve occupational

doses and doses to members ofthepublic as low as reasonably achievable.

,

Posting: j

We have the most current NRC FORM-3, NOTICE TO EMPLOYEES, and it is posted where

employees can read the information. The Employee information notice has not yet been posted

with this form but will be.

Radiation Protection Program (RPP);

At Kennecott Greens Creek Mining Company, our RPP is our operating, safety and emergency

procedures. These procedures serve as a basis for the RPP and radiation safety manual. The

RPP will be reviewed at least on an annual basis.

Occupational and Individual Members of the Public Doses:

Based on the working conditions, physical accessibility and occupancy factors it is estimated that

not more than 2-3 people will routinely be within two to three feet of the devices, for more than

30 minutes a week. The occupancy time for an occupational worker, in a worst case, with the

measured exposure being 2.8 mrem per hour is 62.8 mrem / year

Our workers would not exceed the 500 mrem annual limit or require monitoring. This is also l

well below the 100 mrem annual limit for members of the pubhc.

Should any device be required to move these calculations will be redone to ensure compliance

below the limit of this regulation. This survey will only be done by persons authorized to do so

by the commission.

Answers to specific questions raised by your October 2,1996 letter;

1. Outlines of RSO training for Timothy F. Gibson are enclosed

2. Training and accompanying certificates for portable devices will be obtained before any

are purchased and brought onto the property. This has not been done to this date

because we are not licensed for and have not purchased these devices.

3. A sketch is enclosed where gauges in use are located. The device not in use is located at

our liawk Inlet warehouse facility in a locked " job box" in a marked and secured area of

that warehouse. The RSO has a key to thejob box. Our facility is located on an Island

reachable only by boat or float plane. Everyone coming to or leaving this facility is

known. Only those personnel that are fully safety trained are allowed in the concentrator

where the devices are in use. This training includes an awareness of the devices and their

potential hazards. The survey you request was completed by Ralph fleyer and submitted

as part of his report and noted in this letter under the heading of " occupational an l

individual members of the public doses". j

LOCK-OUT/ TAG-OUT PR.OCEDURE

PURPOSE:

This procedure is to safeguard all employees against personal injury, and present property damage from

operation ofcquipment.

RESPONSIBILITY:

All employces are responsible for taking protectist measures in accordance with this procedure to insure against

inachertent start-up. In addition, notify supenision of the intent to lock-out/ tag-out if operations must cease to

perform the required test. If the shutter must be closed and locked on a gauge containing a radioactist source,

notify the RSO prior to initiating lock-out/ tag-out. Loss of signal at the detector should be verified with the

operator or centrol room. The RSO must also be notified when the locks are ready to be remosed and the shutter

opened.

GENERAL:

No syr, tem (clatrical, mahanical, nuclear or process piping) shall be worked on by an employee unless that

system has been de-energized (ie., brought to a zero energy state), lockedbgged out to present accidental

contact with electricity, hazardous materials, release of stored energy or mosing parts.

EMERGENCY PROCEDURE

A. EMERGENCY PROCEDURES

Emergency procedures are to te instituted at the time of an incident imching desices containing radioactive

material. Incidents could include fire or explosion on the site in an area where desices are installed or stored; the

dislocation of a gauging desice from its installed position; etc. The following gui& lines should be followed in

the event of an emergency.

1. Notify all other p:rsons in the area, and evacuate at once.

2. Notify the necessary emergency response agencies, i.e., fire department.

3. Notify the RSO.

4. Attempt to put out any fire by approved means if a radiation hazard is not immediately evident.

5. Gosem fire fighting or other emergency aethities by the restrictions of the RCO.

6. In the case of a dislocated source, the shutter will be closed if possible; and a sisual inspectim completed to

determine physical damage to the desice. If the shutter cannot be closed, the beam will L: measured to

determine potential exposure levels around the device. Personnel other than those working with the desix will ;

he directed away from the immediate area. The RSO or designx will supenise mosement of the desice to the

storage area where it will be maintained until arrangements can be made for repiir and reinstallation

If the device is directly imched in a fire or explosion, the RSO or designee will provide emergency response

personnel with information regarding the locations of gauges, isotopes and acthitics imohtd. After the

immediate threat has been resohed, the shutter will be closed if possible; a sisual inspection will be completed,

and a radiation sunty done to determine potential exposure lesels in the immediate area. If necessary, the area

will be controlled and properly posted until steps can be taken to afTect any necessary repairs, or relocate the

device to a storage area. Remosal of any gauges shall be performed only by speci6cally licensed persons.

7. No person should be permitted to return to the area without the approsal of the RSO or designee. A list should

be maintained of all entrics.

8. Call for any additional advix or assistance necessary.

9. If possible contamination is imched. the area of tle accident should be restricted. Plant persormel should

make only nccessary entries and investigations in the acci&nt area. No attempt should be made to open or

examine contained material. No attempt should be made to clean up any debris or material imched in the

accident prior to the arrival of properly trained and equipped indhiduals.

10. Prepare a complete history of the emergency and subsequent actions taken

11. If notification is reclutred under the regulations, such notification will be performed ty the RSO or designee

in a timely manner. j

P.O. Box 32199

Juneau, Alaska 99803-2199

SUBJECT: LICENSE AMENDMENT REQUEST

This is in reference to your request dated September 5,1996 for amendment of your

byproduct materiallicense. As many changes have occurred both in your organization and

procedures and in our regulatory requirements, we are asking you to resubmit your license

application in its entirety, without reference to documents which were previously

submitted.

To assist you in this process, we are forwarding a copy of the current information in your

docket file, as you requested. We are also enclosing copies of the leak testing guide and

of the portable and non-portable licensing guides and checklists, copies of an NRC Form 3

and an NRC Form 313, and copies of 10 CFR 19,20,21,30,31,71,150,170, and 171.

The following license conditions, which affect the use of non-portable gauges, will be

added to your license when it is amended:

A. Each gauge shall be tested for the proper operation of the on-off mechanism and

indicator, if any, at no longer than 6-month intervals or at such longer intervals as

specified by the manufacturer and approved by U.S. Nuclear Regulatory Commission.

B. Prior to initial use and after installation, relocation, dismantling, alignment, or any

other activity involving the source or removal of the shielding, the licensee shall ,

assure that a radiological survey is performed to determine radiation levels in

accessible areas around, above, and below the gauge with the shutter open.

This survey shall be performed only by persons authorized to perform such services

by the Commission or an Agreement State.

C. The licensee shall operate each gauge within the manufacturer's specified

temperature and/or environmental limits such that the shielding and shutter

mechanism of the source holder are not compromised.

I

.

,

.

Kennecott Greens Creek Mining Company -2-

.

D. The licensee shall assure that the shutter mechanism is locked in the closed position

during periods when a portion of an individual's body may be subject to the direct

radiation beam. The licensee shall review and modify as appropriate its " lock-out"

procedures whenever a new gauge is obtained to incorporate the device

manufacturer's recommendations.

i

Also, during our review of your amendment request to reactivate your non-portable gauge !

license and to add a portable gauge program, we noted a number of concerns that you l

should address in your response to this letter:

!

1. You should submL outlines of the training which was (or will be) completed by l

Timothy Gibson to document whether the classes included (or will include) training in l

I

installation, initial radiation surveys, gauge relocation, removal from service, and leak

testing. Specify the duration of each class in hours, and indicate whether actual

practice in performing the services was (or will be) included as part of the training.

2. Supply copies of the portable gauge training certificates for the Radiation Safety ;

Officer (RSO) and for any other personnel who will be authorized to use the gauges. I

If this training was supplied by someone other than the device manufacturer, supply j

the name, address, and license number of the organization which provided the I

training. Also, specify whether personnel have experience in actual use of portable i

gauges.

l

3. Submit sketches of areas where portable and non-portable gauges may be stored. '

Describe their locations as precisely as possible. Describe the security procedures to l

'

be used at each location to assure that only authorized users will have access to the

gauges. Also, supply a survey for each location to assure that members of the

public will not receive exposures in excess of 100 mrem / year as required by 10 CFR

20.1301. )

i

4. Specify the RSO's duties and the services which he will perform.

l

5. Describe your leak test procedures, if a vendor will analyze leak tests, specify their

name, address, and license number.

l

6. As your license file indicates that you possess both specifically and generally-

l

licensed gauges (Refer to 10 CFR 31.5), it would be helpful for you to submit a

current inventory of all the gauges at your facilities, in your reply, please indicate .

where the gauges are located and whether they are specifically or generally licensed. l

This will be useful for both licensing and inspection purposes. ;

We will continue the review of your amendment request upon receipt of this information.

In order to continue prompt reviaw of your application, we request that you submit your

response to this letter within 30 days from the date of this letter. Please reply in

duplicate, and refer to Mail Control 572409. If you have questions concerning these

matters, I can be reached at (510) 975-0250.
