Dear Mr. Galler:

Pursuant to Paragraph 2.C (3) (a) of the above referenced Facility License, the following Annual Report hereby submitted.

Paragraph 2.C (3) (a) comprises three (3) subjects which we will designate as: ,

(1) Results of Environmental and Facility Radiation Surveys.

(2) Status of the Facility.

(3) Evaluation of the performance of the Security and Surveillance measures.

These subject reports are attached to this letter and are designated in the same manner as above: (1), (2) and (3).

Very truly yours, TCB:

James R. Bohannon, Jr.

PART A (1) RESULTS OF ENVIRONMENTAL AND FACILITY RADIATION SURVEYS ENVIRONMENTAL AND RADIATION SURVEY REPORTS RELATING TO THE R-63 REACTOR Environmental Surveillance The NCSU Radiation Protection Office (RPO) conducts the environmental surveys on campus. These survey results are reported each six months cover-ing the periods April through September, and October through March. See Part B of this report.

Facility Radiation Surveillance The current ' Possess but not Operate' R-63 Facility License issued 18 March 1974 specifies " requirements for surveillance and monitoring include

. . . (1) two out of three of the present reactor bay monitors and (2) one .

out of three of the present stack monitoring channels . ..

Currently, three out of three reactor bay monitors are in servi.e and two of three stack monitoring channels remain in operatier This level of radiation monitoring more than satisfies the requirements of the Facility.

License. In addition, the NCSU Radiation Protection Office takes a daily air sample in the R-63 bay as supportive surveillance to the basic require-ments of the Facility License. These air samples have yielded no radio-activity over background over one week decay.

. - PART A (2) STATUS OF THE FACILITY Status of the NCSUR-63 Facility is same as reported to the Directorate for Licensing on 17 January 1975 and the Division of Reactor Licensing on 11 March 1975; Phase II of the NCSUR-63 Decommid3ioning Plan has been com-pleted, and the facility is in the Defueled and Standby status.

A Dismantling Plan was filed with the Commission on 2 February 1977 after having been approved by the NCSU Radiation Protection Council.

(3) EVALUATION OF THE PERFORMANCE OF THE SECURITY AND SURVEILLANCE MEASURES Physical barriers are inspected on a periodic schedule and have in every respect met the security requirements for which they were designed.

All surveillance measures in force have been exercised as prescribed in the appropriate procedures with no interruption in facility security status.

1. IUTRODUCTION During the six months covered by this report, environmental radioactivity was observed to decrenac continuously until the last tuo uceks of March uhen fallout from the March 14 atmoc9herie detonation in the Peopics Republic of China at the Lop Uor test site reached thin area.

Local analysis of soil and vegetation camplec for gross alpha and beta activitico has been added to the Environmental Surveillance Program during this reporting period; and coverni additional sampics in the vicinity of the radio-active waste burin 1 groundo have been analyzed for radioactivo content.

2. AIR MOUITORIUG Airborne gross beta activity (Tabic 2.2) decreased to relatively lou stabic readingo uithin a feu uceks after the September 17, 1977 detonation uhich una reported in the April 1 to September 30, 1977 Environmental Radiation Surveil-lance Report. It then reached a new high during the ucck of March 20, 1978 -

shortly af ter the most recent atmospheric nucicar detonation. Campus averages for typical lung hazardo are reported in Tabic 2.3. Shorter lived fiosion products and Cesium-137 are reported in Tobic 2.4 for the firct tuo and last tuo uccho of the reporting period. Theoc sciccted intervals shou the decline in fallout concentrationn following the September 1977 test and the charp increnac follouing the March 1978 shot.

Routine repairs on high volume air samplera are nou being performed in the Radiation Protection Office. This action in crpected to minimize doun time and reduce operating costo.

3. MILK Strontium-90 activity in reported for monthly milk campics in Tabic 3.1.

One campic ocnt to Telodyne Icotopco for contracted analysis is also reported in Tabic 3.1.

Iodine-131 activity has remained belou detection limits in U.C. State University Dairy milk in spite of the preacnce of this nuclide in air sampics taken shortly af ter atmospheric nuclear detonationo. This abacnce may be explained by the fact that the dairy cattic on the F.C. State University farms are primarily silage fed rather than grazed. The cattic do graze some during the summer montho uhen ampic grass is availabic; however oilage remains their primary dict even then. Also, at the timco of the last six atmospheric testo by the Peoples Republic of China, littic or no grazing was donc by UCSU Dairy cattic.

4. SURFACC HATER Specific activitics for groso beta and sc1ceted gemma emitters nre reported in Tabic 4.1 along uith Strontium-90 activity. The December sampics show the highest activity for Strontium-90 and gross beta. This may represent a delay in fallout from the September 1977 atmospheric test being unshed into Rocky Branch Crock. This hypotheolo vill be tested by checking sampics in future months for a corresponding increase follotdng subsequent detonations.

5. SOIL In t.ddition to the dorth, South, East and Ucst soil sampics, which ucro analyzed both locally and at Toledync Isotopco, six soil sampics ucre taken
