CS-78-90 ca Mr. J. P. O'Reilly, Director Docket No. 50-302 Office of Inspection & Enforcement License No. DPR-72 U.S. Nuclear Regulatory Commission REF: RII-SCE 230 Peachtree St.
N.W., Suite 818 50-302/78-5 Atlanta, GA 30303
Dear Mr. O'Reilly:
We offer the following response to the apparent Items of Noncompliance in the referenced Inspection Report.
Before discussing the specific items contained in the Notice of Viola-tion, we would like to address the modifications presently being ac-complished to prevent recurrence of unplanned releases of radioactive gases resulting from blown loop seals. These modifications will be accomplished during the current outage and a completion date of 15 August 1978 has been established.
A.
Technical Specification 6.11 requires that radiation pro-tection procedures be adhered to.
Radiation Protection Procedure RP-202, " Radiological Surveys" specifies areas in which routine periodic radiation and contamination surveys 1
are to be performed.
Contrary to the procedural requirements: (1) Daily radiation and contamination surveys performed in the Auxiliary Building on 18 days during the third quarter 1977 and first quarter 1978 were inccmplete in that not all areas specified by procedure RP-202 were surveyed; (2) no weekly contamination or radiation surveys have been performed of the Diesel Gen-erator Building; and (3) weekly radiation and contamination surveys performed for 3 weeks between October 4, 1977 and February 14, 1978, were incomplete in that not all areas specified by Procedure RP-202 were surveyed.
A - Response: Radiation Protection Procedure RP-202 will be revised and will be clarified as to the requirements for routine radiatian surveys, including the requirement of radiation surveys within s

J. P. O'Reilly REF: SCE 50-302/78-5 Page 2 locked cubicles. As an interim measure, until the.evision of RP-202, Cham / Rad personnel have been instructed to perform weekly surveys of the emergency diesel generator cubicles. All areas specified in RP-202 shall be surveyed and full compliance shall be achieved by 1 June 1978.
B.
Technical Specification 6.8.1 required implementation of procedures, including administrative and operating procedures.
Operating Procedure OP-205, Section 8,
" Hydrogen Addition and Degasification" required, in part, the return of vaste gas system valves to normal positions at the conclusion reactor coolant degasifica-tion and the periodic (hourly) depressurization of the waste gas compressors. Administrative Instruction AI-500, Section 5.1 required the completion of signoff sheets used in conjunction with plant procedures.
Contrary to the above: (1) On March 5, 1978, vaste gas system valves were not returned to normal positions until approximately twelve hours after degasification was com-plete; (2) on March 5,1978, periodic depressurization of the waste gas header was not performed; and (3) on March 3-5 signoff sheets pursuant to Procedure OP-205, Section 8, were not completed.
l Yhe above examples of failure to follow procedures resulted in, or contributed to, the unplanned release of 128 curies of radioactive nobel gases on March 5, 1978.
B - Response: A review of the temporary change to OP-205 indicated that this temporary change was initiated on 3 March 1978 and was te minated on 5 March 1978 after the investigation of the unplanned radioactive gas release.
In order to conform with Section 5.1 of Administrative Instruction AI-400, concerned personnel have been instructed to complete and verify all steps of Operating Procedures and this verification will be documented by signature.
Operations personnel have been instructed to ensure that all tempor-ary procedure changes will be returned to the Shift Supervisor if a break in continuity of the procedure occurs prior to its com-plation. All Shift Supervisors have been instructed to flag the procedure in the Shift Supervisor Log, stating the conditions necessary for re-initiation or completion of the procedure.

REF: SCE 50-302/78-5 Page 3 With regard to Paragraph B.2(2) of the Notice d Viointion, an in-vestigation of existing plant logs revealed that, in fact, periodic depressurization of the vaste gas header was performed at 0055, 0340, 0605, 0735, 1055, and 1500 on 5 March 1978. We feel this portion of the Notice g Violation to be in error and should be withdrawn.
Full compliance has been achieved as of this date.

Very truly yours, u). 9.5-&
