LICENSE AND TECHNICAL SPECIFICATIONS CHANGE REQUEST -

ALLOWABLE QUANTITY OF SOURCE MATERIAL Attached are .three (3) originals and thirty-seven (37) conformed copies of a request to ch~bge_the Palisades Provisional Operating.License DPR-20 and the Palisades T~l:HiH_cal -specifications.,. The attached proposal requests a change to the allowable quantity of Cesium-137 as a.._~ealed calil;>ration source specified in the Palisades Provisional Operating License. An increase in this limit is required to allow possession of sealed sources for calibration of high range radiation detection instruments. The addition of the Cesium-137 calibration source is to fulfill a commitment to INPO. Since the receipt of this additional source is dependent upon approval of the requested License amendment we ask for prompt NRC action to approve this change.

The proposal also requests the addition of new technical specifications that describe the leak test requirements for sealed. sources. The additional requirements are adopted from those provided in the CE Standard Technical Specifications (NUREG-0212, rev. 2) section 3/4.7.10. A revised Table of Contents and correction of a typographical error are also included in this request.

In a letter dated January 24, 1975, to Consumers Power Company, Big Rock Point Docket 50-155, D L Ziemann, NRC, described improvements that could be made to the license in regard to special nuclear, byproduct, and source materials.

Enclosed with the letter were standardized requirements which removed reference to specific quantities of the materials. The standardized requirements were suggested to licensees to circumvent the need for issuing, on a priority basis, a license amendment when the required quantities of on-site material were to be changed-.

Docket 50-255 Request for Change to the Provisional Operating License DPR-20 and the Technical S~ecif ications For the reasons hereinafter set forth, it is requested that the Provisional Operating License DPR-20, and the Technical Specifications, Docket 50-255, issued to Consumers Power Company on October 16, 1972, for the Palisades Plant be changed as described in Section I below:

I. Changes:

A. Change item 2(C) of the Provisional .Operating License to read:

"C. Pursuant to the Act and 10CFR30,. "Rules of General Applicability _of Licensing of Byproduct Material", to receive,.

possess, and use in connection with operation of the facility 1500 curies of Polonium-210 as two sealed sources not to exceed 750 curies each, 1000 curies of Cesium-137 as multiple

. sealed calibration sources and up to 500 millicuries per nuclide of any byproduct material with Atomic Numbers 3 to 83, inclusive, without restriction to chemical and physical form to a total of 10. curies;"

B. Revise the Table of Contents to remove deleted section 3.1.9, add Listing of Tables and Figures, add section 6.2.1 Sealed Source Contamination, and make miscellaneous corrections.

C. Revise Table 3.17.4 note (g) to read:

"(g) Calculate the Quandrant Power Tilt using the excore readings

  • at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.when the excore detectors deviation*alarms are inoperable."

D. Add a new Section 6.21 to read:

"6.21 SEALED SOURCE CONTAMINATION 6.21.1 Each sealed source containing radioactive material either in excess of 100 microcuries of beta and/or gamma emitting material or 5 microcuries of alpha emitting mate.rial shall be fre~ 9f great~r than or equal. to 0. 005 microcurie~s of removable contamination.

6.21.2 With a sealed source having removable contamination in excess of 0.005 microcuries, immediately withdraw the sealed source from use and either:

1. Decontaminate and repair the sealed source, or TS0586-0001A-LI01-NL04

2

2. Dispose of the sealed source in accordance with applicable regulations.

6.21.3 Each category of sealed sources as described in 6.21.l (excluding startup sources and fission detectors previously subjected to core flux) with a half-life greater than 30 days (excluding Hydrogen-3), and in any other form than gas, shall be tested for leakage and/or contamination at intervals not to exceed six months.

6.21.4 The test shall be performed by the licensee or by other persons specifically authorized by the Commission or an Agreement State. The test method shall have a detection sensitivity of at least 0.005 microcuries per test sample.

6.21.5 The test sample shall be taken from the sealed source or, in the case of permanently mounted sources, from the surfaces of the mounting device on which contamination would be expected to accumulate.

6.21.6 The peri~dic leak test does not apply to sealed sources that are stored and not being used. These sources shall be tested prior to use or transfer to another licensee, unless tested within the previous six months. Sealed sources which are continuously enclosed within .a shielded mechanism (ie, sealed sources within radiation monitoring or boron measuring devices) are considered to be stored and need not be tested unless they are removed from the shielded mechanism.

6.21.7 S~aled sources transferred without a certificate indicating the last test date shall be tested prior to being placed in use.

6.21.8 A report shall be prepared and submitted to the Commission on an annual basis if sealed source leakage tests reveal the presence of greater than or equal to 0.005 microcuries of removable contamination."

II. Discussion The proposed change requests an increase in the possession limit for Cesium-137 as sealed sources. The change consolidates the individual listing of each Cesium-137 source into a single stated quantity. In addition, a new administrative section i~ reque.sted to descr:ibe the leak -test --requirements for calibration sources. Also a typographical error that was incorporated in Amendment 96, 1/30/86 has been corrected in item I.C.

The increased Cesium-137 quantity limit is needed to allow the possession of a calibration source for high range radiation detection instruments. The source will allow the verification of the accuracy of these instruments on all measurement scales. This is a des*irable TS0586-0001A-LI01-NL04

3 feature that can be expected to improve radiation protection capabilities.

The consolidation of the individual Cesium-137 sources into a single possession limit is intended to remove the need for further amendments.

The additional administrative requirements are based on the guidance provided in the Standard Technical Specifications. These requirements have been modified sufficiently for application to the Palisades Plant. The significant variations and other items of interest are as follows:

1. The proposed Section 6.21.5 includes provisions that allow for a test sample to be taken from the surface of a mounting device.

This allowance was deemed necessary to limit the potential dose received from attempting to achieve direct access to these sources.

2. Current Technical Specifications provide record retention requirements for sealed source leak tests in Section 6.10.l(i).

Analysis of No Significant Hazards Considerations Possession of byproduct materials is licensed under the requirements of 10CFR30. Typically, commercial nuclear plants have incorporated this byproduct license into the plant operating license. Inclusion in the operating license necessitates an application for an amendment to the byproduct license through a more restrictive process than that prescribed by 10CFR30.

A request to amend a* 10CFR30 byproduct license does not require an analysis of the significant hazards considerations. As provided in 10CFR30.38, the application for amendment needs only to specify the desired changes and the grounds for the change. This information has been detailed in the preceding Sections I and II.

Although not required by 10CFR30, the significant hazards evaluation of this change is presented in support of the request for an amendment to the operating license. The effects of the additional administra-tive requirements are also presented. The analysis is as follows:

1. The requested changes do not result in an increase in the probability or consequences of a previously evaluated accident.

The change affects the aliowable quantity ~f Ce~i!llll-137 as sealed source material. The change also provides additional admin-istrative requirements for the control of sealed sources. The types of occurrences that would result from sealed sources are not evaluated in the FSAR. Formal evaluation of these potential occurrences is not required to assure nuclear safety, and does not relate to nuclear safety or previously evaluated accidents.

TS0586-0001A-LI01-NL04

2. The change does not create the possibility of a new or different kind of accident. The operating license previously authorized the

-p-oss-e*s-sion*-o*f--seal-ed--s*o*ur*c*es .- Potent-ia.1-occurrence-s-from-th-eSe___ - - -- ---*----- --- --

sources were not required to be formally analyzed. An analysis remains unnecessary for this category of occurrence.

The administrative requirements provided by this proposal result in additional controls not presently included in the Technical Specifications. As such, these controls will enhance the radiation safety program and the control of sealed sources. Also, these requirements are not new in that the leak testing of sealed sources is an existing program. This request only results in further emphasis on the importance of this program.

3. The change does not result in a reduction in the margin of safety.

The increased possession limit affects an aspect of plant operation that is unrelated to nuclear safety. The provisions for formalized leak testing requirements in conjunction with existing procedural controls are adequate to ensure no reduction in any type of radiological safety margin.

III. Conclusion The Palisades Plant Review Committee has reviewed this Technical Specification Change Request and has determined that this' change does not involve an unreviewed safety question and therefore involves no significant hazards consideration. This change has also been reviewed under the cognizance of the Nuclear Safety Board. A copy of this Technical Specification Change Request has been sent to the State of*

Michigan official designated to receive such Amendments to the

  • Operating License.
