- I'7' N 1
Department of the Navy Naval Undersea Rescarch & Development Center San Diego, California License Nos. 4-13495-1, 4-13452-1, and SNM-1154 1.
An announced initial inspection of the subject licensedprogramspas conducted on March 10, 1970, by R. Fish, Region V Inspector, Division of Compliance.
Mr. Al Smith, Head of the Safety Division and Radiation Safety Officer, represented the licensee during the entire inspection.
Mr. F. K. Kawahara, Engineer and authorized user on license No. 4-13495-1, was interviewed during the inspection. No representative of the State of California was present during the inspection.
2.
At the conclusion of the inspection a verbal summary of the findings was presented to LCDR William W. MacKensic, Head of the Command Administra-tion Department, and Al Smith. No items of noncompliance were noted with respect to activitics under license Nos. 4-13495-1 and 4-13452-1 and a Form AEC-591, reflecting this result was issued for cach license. The l
licensee did possess 5 plated, Pu counting standards, varying in activity 5
between 83 and 2.91 X 10 dpm, without their being authorized by a SNX l
license - SNM-1154 authorizes the possession of a PuBc neutron source, PuO2 microspheres and U-235 only. A Form AEC-592 will be issued for the unauthorized possession of the Pu counting standards.
Mr. Smith said the standards were overlooked when the license application was prepared because of the small amounts of activity involved. The sources were obtained from NRDL which was being disestablished.
Mr. Smith said he would prepare an application for license amendment requesting thesc l

p
,m N-)
sources be added to the license.
LCDR MacKenzio confirmed that action would be taken to co= ply with the requirements.
3.
The Co==anding Officer of Naval Undersea Research and pevelopment Centor (NUC) is Captain C. B. Bishop. The Chief Staff Officer is CDR G. R.
Langford. The Technical Director is Dr. William B. McLean. Both CDR Langford and Dr. McLean rcport to Captain Bishop. Civilian heads of Department level groups report to Dr. McLean. Military heads of Department level groups report to CDR Langford. The Departments are further divided into Divisions and Branches. As head of the Safety Division Mr. Smith reports to LCDR MacKenzic, Head of the Command Administration Department. There are two Safety Branchos (non-radio-logical) reporting to Mr. Smith.
Mr. Kawahara, authorized user listed on license No. 4-13495-1, is the only person using radioactiva caterials under the subject licenses at this time.
Mr. Kawahara is in the Systems Engineering Branch and presently reports to I. P. Lemaire, who is the Head of the Advanced Systems Division. Mr. Lemaire reports to Mr.
H. R. Talkington, Head of the Ocean Engineering Department. With the exception of those being used by Kawahara, all radioactive materials possessed under the subject license: are stored and under the control of Mr. Smith. Attached to these notes is a NUC code Directory.
4.
NUC has facilitics and personnel at Pasadena, Point Mugu Naval Air Station and San Clemente Island. Use of radioactive materials at San Ciccanto Island is authorized under license Nos. 4-13495-1 and SNM-ll54. Use of radioactive materials at Pasadena is authorized under licens Nos. 4-5645-2 and -4.
Use of radioactive materials at Point Mugu is authorized under license No. 4-5645-3. This -3 license is being used by the Environmental Physiology Branch. Mr. Smith said there is a real possibility that in the next year or two the Environmental Physiology Branch will bc
.O p
V v
moved entirely to San Diego - some are already in the process of moving.
5.
Mr. Smith is the. Radiation Safety Officer (RS0) for NUC. With respect to licensed activitics at Point Mugu, Mr. Walter Milne, Pacific Missile Range (at Pt. Mugu) Radiological Safety Officer, has been performing the RSO function.
Mr. Smith said he was presently in the process of preparing a radiation safety manual for'NUC.
LCDR MacKenzie noted the manual was scheduled to be complete by February 22, 1970. Section D of the September 26, 1969, application for SNM-1154 describes generally the health and safecy measures to be followed when working with SNM. Some of the Naval Radiological Dofense Laboratory (NRDL) radiation safety procedures applicabic to the SNAP-21 environmental tests bave been incorporated by Condition 10 of license No. 4-13495-1.
Mr. Smith vill be the only health physicist at the San Diego. facility. He will also have overall health physics responsibilities at the licensce's facilitics at Pasadena and Point Mugu.
Mr. Smith said that when the radiation safety program is fully installed, signified by approval of the Manual, there will be an isotope committee.
6.
For the present all isotope purchases must be approved by Al Smith.
All radioactive materials possessed by the NUC were received from NRDL.
Transfer papers were prepared by NRDL and copics are possessed by Mr. Smith With respect to the two SNAP-21 units, containing approxi-mately 30,000 curies Sr-90 each, and the 8.36 mgms of Puo microsphercs (6.8 mgms Pu-238) only a transfer of responsibility occurred because the items were aircady at San Clemente Island. The Puo was officially 2
transferred on February 11, 1970, and the SNAP-21 units on December 1, 1969. ' The 107 gms of U-235,16 gm PuBc neutron source and the byproduct material possessed under license No.
4-13452 -l
O o
were roccived, according to Mr. Smith's records, on November 3,1969.
The records of roccipt were checked against the isotopes, quantitics and forms listed in license No. 4-13452-1.
In the case of tritium, the licensee possessed 20 curies as targets and did not roccive the
~
tritium contaminated accelerator and associated equipment. Some of the other isotopes were not received also.
In two instances, Ti-44 and Cd-109, i
the records indicated receipt of slightly larger quantitics than authorized.
Mr. Smith said he made the application on the basis of actual quantitics (allowing for use and decay) and the forms may reflect NRDL records.
According to Mr. Smith he had not yet opened the shipping containers to verify the facts. On the basis of Mr. Smith's statements there seemed to be reasonable assurance that quantity limits in the. license had not been exceeded.
7.
The licensee is presently storing all radioactive materials possessed at the San Diego facility in a locked shed behind Building 120. The shed is about 10 feet by 10 fect by 7.fcet high. The only openings are a small vent, which has a cover, and the door. The door is secured by l
a padlock and only Mr. Smith and LCDR MacKenzie have keys to the lock.
A rope barricade has been placed around the shed to establish a rc tricted t
area. The shed is inside a fenced yard which is locked during non-regular working hours. Guards control the entrance of persons into the NUC facility.
i 8.
The SNAP-21 units are presently located on the end of a pier - see attachment to letter dated November 26,1968, (9900 Ser 354-0516) which is referenced in condition 10 of the applicable license. According to Mr. Smith the shore end of the pier is fenced and the top of the pior is 20 feet above the water with no ladders leading to the water line.
O
~
-s-The gate in the fence is locked. The picr is checked several times cach day by NUC security guards. The licensee is presently working on the water pumping systems and the inline radiation detectors to assure reliability. The site was visited during the veck on March 2, by Mr. Smith, Mr. F. Kawahara and others to perform this work.
9.
The Puo2 microsphores arc inside a seccl box which has been placed on the floor of the channel near the pier. The box is scaled except for two metal tubes open to the ocean vator which allows convection but not direct flow of water into and out of the box. The microspheres arc embedded and distributed in a few inches of ocean silt placed in the bottom of the box. The box has a marker attached. The experiment has been in operation about one year.
- 10. The door to the shed was posted in accordance with 20.203(b) and -(c)(1).
A Form AEC-3 was also posted on the door.
Other copics of Form AEC-3 were posted in Mr. Smith's office, on the bulletin board in Chemistry lab which isotopes may be used in the future and in the Radiation Physics trailer. The container with the Pu3e neutron source was labelled as required by 20.203(f). An URIPS SNAP device, containing 7200 Ci of Sr-90 and possessed under license No. 8-11817-2, was stored in the
(
shed and labelled as required by 20.203(f). The other materials in the l
l shed were still inside their shipping containers (unopened) cach of which was labell3d in accordance with DOT regulations. According to Mr. Smith the fence at the end of the picr on San C1ccente Island is posted in accordance with 20.203(b) and (c)(1). The two SNAP-21 devices -
were said to be labelled in accordance with the NRDL license submissions.

6-11.
Mr. Smith has a variety of instruments which are capable of detceting and =casuring alpha, beta, beta-gn==a and neutron radiation. Some of this equipment is shown in the September 26, 1969, application for the SNM-ll54 license. Naval instruments arc repaired and calibrated by the Radiac Repair Facility at San Diego. Some instruments arc.
calibrated periodically by Mr. Smith using the sources at the Radiac Repair Facility.
- 12. Mr. Smith has made surveys of San Clemente Island and around the storage shed behind Building 120. According to the records radiation levels at the exposed surfaces of the SNAP-21 devices is 100 mr/hr at contact and 2 mr/hr at 2 feet away. Wipes on the surface of the devices and the surrounding arca showed no removable contamination above background.
Radiation icvels at the surface of the storage shed behind Building 120 were a maximum of 2 mr/hr. They reduced to 0.5 mr/hr at the rope.
- 13. The licensee uses film badges to monitor personnel exposures. TLD dosicoters are used to monitor exposures received by personnel working underwater at San Clemente Island. Both direct and indirect reading dosicoters are possessed by the licensce. The films are navy issue with
[
beta-gamma sensitivity. Neutron films are to be issued to those using the PuBe neutron source. All film badges are developed and evaluated by the Bethesda Naval Hospital. An.cxposure history is being obtained for NUC employees who are likely to receive any exposure. All current exposures are being recorded on Form DDil41, one for each person (including contractor personnel).

- 14. The only leak test required is for the Pu3c neutron source. The licenscc has the NRDL leak test records which show the source was last tested on March 8, 1969. Mr. Smith leak tested the source on March 9,1970, and the results which have been recorded in microcuries, showed.
2 X 10-7 uCi removabic contamination. This test was within 6 months of the receipt of the source which has not been used to date. Thus the licensee has complied with the leak test requirement.
'15.
In place of a leak test requirement for the SNAP-21. units the inline detector has been found to be acceptable by DML.
During the last visit to San Clemente Island, Mr. Smith sa= pled the water 'in cach.
device to determine where there was any leakage from the sources. The result s of the test showed 7 X 10-7 and 5.5 X 10-5 uci/cc respectively.
This should be compared to the 1 X 10-4 uC1/cc maximum concentration permitted to be relcased to the ocean (Condition ll.A of the license).
16.
Also attached to these notes is a copy of the transfer approval and supporting papers authorizing NUC to assume the responsibilitics for the SNAP-21 experiments at San Clemente Island. This review and approval was required by Condition-14 of the licensc.
- 17. There have been no incidents or unusual circumstances involving radioactive materials possessed under the subject licensecs since the materials were received or responsibility assumed. There has been no radioactive vasto disposal under these 3 licenses to date.
