RCVIEW 0F TCP'S REQUEST FOR TERiilNATION OF MATERIALS LICENSE N0. S!!M-1677 AND RELEASE OF THE FACILITY FOR UNRESTRICTED USE REVIEWER:
A. L. Soong I.
Background
Teledyne ca.it Products of Pomona, California, is the holder of Materials License No. SNM-1677. The lienses was issued in 197C, anc' is due to axpire on September 30, 1981. The licensee is authorind to possess and use up to 4800 grams of U-235 as contained in aluminum contaminated with :.pecial nuclear material (SNM) enriched to a maximum of 1.5% in the U-235 isotope. The licensee had planned to melt cast aluminum billets that contattled small quantities of Sitt and cast them into com-pressor stator assemblies for use by Union Carbide Corporation (a DOE l
pri'ne contractor) in the gaseous diffusion plants; however, because of technical difficulties, only one aluminum casting was made that contained licensed matirjal and all licensed matetial was returned to Union Carbide Corporation. Paducah, Kentucky. By letter dated January 8,1980, TCP re-quested that itsMaterials License be terninated.
By letter dated September 18, 1980, the Comission indicated to the licensee that they must provide the Comission with results of a radiation survey of the facilities to show that the contamination levels are below those limits specifico in Tho'a 1 of the Comission's " Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unre-stricted Use or Temination of I.icense for Byproduct Source or Special Nuclear Material," dated flovember 1976 (Enclosure 1). These guidelines also describe tne procedures to be followed and infomation required prior to termination of the Materials License.
By lecter dated February 24, 1981, TCP submitted a final radiolcgical survey report (Enclosure 2) showing that measured contamination levels in the melting pot and storage area of the faci'ity were below the limits as specified in the above guidelines.
By letter dated March 19,1981 (Enclosure 3), IE concluded, based on the result of IE's confimatory survey of the facility, that the centamination levels in the facility met the Comissior guidelines for releasing the ~
facility for unrestricted _uit_AnLreIEInended temination ef_fhe_Special OFFICE k SlhfONb "I

, JUL 3 01981 II. Discussion The licensee's radiological survey repcrt shows that the contamination level is at background level, and IE's confimatory survey verifies that the residual contamination level in the facility is insignificant and below the guidelines for releasing the facility for unrestricted use.
On July 7,1981, I discussed this case with Mr. R. Thomas, IE Region V inspector. He indicated that all the equipment for handling the licensed material had been decontaminated by the licensee to the level below the guideline's limits.
The licensee's Nuclear Material Transaction Report, NRC Form 741, shows that TCP had returned the licensed material to Union Carbide Corporation at Paducah, Kentucky on August 29, 1977. This was confinned by a telephone conversation with Mr. Kraemer of Union Carbide Corporation.
on July 9, 1981.
III. Conclusion Based on the findings in the current assessment, the release of the Tcledyne Cast Products facility for unrestricted use represents an insignificant risk to the public health and safety to the environment.
Therefore, it is recommended that TCP's Matetlais License No. SNM-1677 be terminated and the facility released for unrestricted use, Or* gina151gned By:

Person Contacted Stephen Beal, Research & Development Engineer MOTE:
Messrs. E. W. Dansby, President, and E. H. Bossing, Radiation Safety Officer, were not available during this inspection.
B.
Ba:karound Pursuant to a letter dated January 8,1980, a request vas made by.the licensee to have License Number SNM-1677 terminated since all materials had been transferred to Union Carbide Corporation, Paducah, Kentucky which is a 00E contractor. Subsequently, an NRC letter dated September 18, 1980 stated that the licensee must perform a radiation survey of the facilities and submit the results to the Commission. A confirmatory survey would be conducted by NRC prior to termination ~of the license.
The facilities would be released for unrestricted use if the contamination levels are below those specified in Table I of the NRC " Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct Source or Special Nuclear Material. "
C.
Licensea's Survey Results Enclosed as Appendix A is the Monitoring Survey Report, dated 12/13/79, which indicates the results of the survey conducted by the licensee.
The licensee's survey data do not show any radiation or contamination levels present in the melting pot or storage areas.
D.
Confirmatory Survey Results On December 16, 1980, the inspector conducted a confirmatory survey in the storage area, handling areas, and melting pot areas where the SNM had been used or stored.
. An alpha survey was conducted using a Ludium Alpha Meter, Model 12, with an Air Proportional Alpha Probe, Mcdel 43-4.
In the areas examined, there were no significant contamination levels observed.
A beta-gamma survey was also conducted using a DesimetertCorporation; Mini CON-RAD Model No. 3032 with a thin end-window GM detector.
In the areas examined, there were no significant radiation levels observed.
Both of the above instruments were in current calibration.

A ' check for loose radioactive contamination was also conducted by the inspector in the areas centioned above.
Particular attention was placed on the floor areas, celting pots, and objects in the storage area.
Twelve swipes were taken during the inspection. The swipes'were counted in the NRC -laboratory NMC Model PC-55 Gas Proportional Counter which has an alpha efficiency of 49.0%.
The counting results indicated no significant contamination levels.
E.
Conclusions Based upon the results of this inspection it appear's that all HRC licensed materials have been transferred to a DOE contractor.
It also appears that the licensee has properly decontaminated Lthe facilities and there are no significant radiation or contamination levels present.
It would appear.that the areas surveyed could be released for unrestricted use.
F.
Exit Interview Since the President and Radiation Safety Officer were not available at the tire of the inspection, only a brief discussior, was held with Mr.
Stephen Beal. The results of the confirmatory survey were discussed.

Dear Mr. Thomas:
In-Accordance with your request and the " Guidelines for Decontamination of Facilities and Equipment, etc." of November-1976, enclosed please find the survey. conducted at Teledyne-Cast Products by myself.
The survey was performed using an EON Corporation, Portable Survey Meter, PSM-700 that had just been calibrated by. an outside laboratory.
No readings above background level were found in any area where the licensed material was stored, transported, handled, melted, or repackaged for return to it's original source, UNION CARBIDE.
Wipe samples taken on floor, corners, etc.,
also showed no meter readings above background.
I hope this information is satisfactory.
If more infor-cation is required, please contact me.
Sincerely, TELEDYNE CAST PRODUCTS E
