Docket No. 50-335 License No.
DPR-67 EA 86-53 During Nuclear Regulatory Commission (NRC) inspections conducted on January 8-9, and February 25-26, 1986, violations of NRC requirements were identified.
The violations involved the failure to establish radiological control procedures and to perform adequate evaluations of personnel exposures.
In accordance with the "General Statement of Policv and Procedure for.NRC Enforcement Actions,"
( 1985),
the violations are listed below:
A.
Technical Specification 6. 11 requires that procedures for personnel radiation protection shall be prepared consistent with the requirements of 10 CFR Part 20 and shall be approved, maintained, and adhered to for all operations involving personnel radiation exposure.
Technical Specification 6.8. 1a provides that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33, Revision 2, February 1978.
Appendix "A" of the referenced Regulatory Guide, number 7.e., lists Radiation Protection Procedures as activities to be covered by written procedures.
Technical Specification 6.8.2 provides that procedures specified in Technical Specification 6.8. 1a and changes thereto shall be reviewed by the Facilities Review Group (FRG) and approved by the Plant Manager prior to implementation and be reviewed periodically as set forth in administrative procedures.
Contrary to the above, during the period November through December 1985, in which the licensee performed sludge lancing of the Unit 1 steam generator, procedures for personnel radiation protection were not prepared which specified the radiation protection requirements for the Unit 1 steam qenerator sludge lancing.
Informal internal memoranda were used in lieu of approved procedures to specify the radiation protection controls for the steam generator work.
B.
10 CFR 20.201(b) requires that each licensee make or cause to be made such surveys as may be necessary for the licensee to comply with the regulations in 10 CFR Part 20 and are reasonable under the circumstances to evaluate the extent of radiation hazards that may be present.
Contrary to the above, during the period of November through December 1985, adequate surveys (evaluations) of personnel whole body radiation exposures during the Unit 1 steam generator sludge lancing were not performed.
Specifically, worker assigned pocket dosimeters, used by the licensee as whole body dose control devices, were not evaluated periodically as a worker removed his arm from the steam generator handhole prior to permitting him to reinsert his arm so as to facilitate comparisons between predicted and actual exposures.
As a result, on December 3,
- 1985, a worker was found to have exceeded his allowed administrative exposure limit of 565 millirem by 234 millirem after having made four arm entries into the steam generator handhole.

'J II
Contrary'to the above, during the period of November through December
- 1985, no evaluations were performed prior to sludge lancing work to determine that the direct reading-dosimeters, used as exposure control devices, adequately measured individual exposures under the conditions and in the geometry that they were going to be used.
The licensee subsequently determined that the direct reading dosimeters had underresponded 26 to 40 percent.
The effect of the underresponse was that worker exposures were higher than they were expected to be.
Collectively, these violations have been evaluated as a Severity Level III problem (Supplement IV).
Pursuant.to the provisions of 10 CFR 2.201, Florida Power and Light Company is required to submit to this Office within 30 days of the date of the -letter transmitting this Notice a written statement or explanation in reply including for each violation:
( 1) the reasons for the violation if admitted, (2) the corrective steps which have been taken and the results
- achieved, (3) corrective steps which will be taken to avoid further violations, and (4) the date when full compliance will be achieved.
Where good cause is shown, consideration will be given to extending the response time.
