SUBJECT:
SAFETY EVALUATION REPORT, LICENSE AMENDMENT APPLICATION 3
DATED NOVEMBER 19, 1987, RE RECEIPT, POSSESSION, AND INSTALLATION OF CF-252 SOURCES IN NEW FUEL 1.
Backcround On November 19, 1987, CECO submitted in application for license amendment requesting the receipt, possession and installation of two Cf-252 startup sources in two new fuel assemblies. At the present time, the sources are being stored under Byproduct Materials License 12-05650-17. To authorize the receipt, possession and installation of the Cf-252 sources, the staff recommends the following conditions:
6.B. Cf-252 7.B. In Cf neutron sources 8.B. 450 millicuries total II. Discussion A.
Radiation Safety The requested materials are sealed sources and will be used for startup purpose in the restrictive area. The staff feels that the licensee's existing NRC-approved radiological safety program is adequate to protect the employees and the public.
The licensee has not committed to a leak testina of the requested Cf-252 sealed source under this license. Accordingly, the staff recommends ti.-
following license condition:
The licensee shall comply with the provisions of Annex A, " License Condition for Leak Testing of Cf-252 Sealed Sources."

l B.
Nuclear Criticality Safety The installation the sources will have minimal effects on the k-of the sto~ age systen. EventhoughtheneutronpopulationincreasesintheNtwo localized areas, the shape and configuration of the storage system remains unchanged and therefore a change in the neutron gain to loss ratio will not OCCUR.
C.
Environmental This licensing action is in accordance with 10 CFR 51.22(c)(10) and therefore, neither an Environmental Impact Statement nor an Environmental Assessment is warra nted.
III. Findino/ Recommendation The staff finds that the proposed change in the license will have no adverse effect on the public health and safety or on the environment. Approval of the application is recommended.

l LICENSE CONDITION FOR LEAK TESTING t
0F CF-252 SEALED SOURCES l
A.
Each sealed scurce shall be tested for leakage at intervals not to exceed 6 months.
In the absence of a certificate from a transferor indicating that a test has been made within 6 months prior to the transfer, the sealed source shall not be put into use until tested.
The periodic leak test required by this condition does not apply to sealed sources that are stored and not being used. The sources excepted from this test shall be tested for leakage prior to any use or transfer to another person unless they have been leak tested within 6 months prior to the date of use or transfer.
B.
The test shall be capable of detecti" +5e presence of 0.005 microcurie of alpha removable contamination on the tet.t e ple. The test sample shall be taken from th& Wur e or from appropriate accessible surfaces of the container or device in which the sealed source is mounted or stored on which one night expect contamination to ac:umulate.
Records of leak test results shall be kept in units of ricrocuries ano maintained for inspection by the Commission.
C..
If the test reveals the presence of 0.005 microcurie or more of removable contamination, the licensee shall immediately withdraw the sealed source from use and shall cause it to be decontaminated and repaired by a person appropriately licensed to make such repairs or to be disposed of in accordance with the Commission's regulations.
Within 5 days after determining that any source has leaked, the licensee shall file a report with the Director, Division of Industrial and Medical Nuclear Safety, U. S. Nuclear Regulatory Comission, Washington, DC 20555, describing the source, test results, extent of contamination, apparent or suspected cause of source failure, and corrective action taken. A copy of the report shall be sent to the Administrator of the appropriate NRC Regional Office listed in Appendix D of Title 10, Code of Federal Regulations, Part 20.
