Attention: Mr. John J. Mattimoe
Assistant General Manager and Chief Engineer
Gentlemen:
Subject: NRC Inspection Report
This refers to the inspection conducted by Mr. R. F. Fish of this office
on January 21-25,'1980 of activities authorized by NRC License No. DPR-54,
and to the discussion of our findings held by Mr. Fish with Mr. Pierre
Oubre and other members of your staff at the conclusion of the inspection.
Areas examined during this inspection are described in the enclosed inspec-
tion report. Within these areas, the inspection consisted of selective
examinations of procedures and representative records, interviews with
personnel, and observations by the inspector.
Based on the results of this inspection, it appears that one of your activ-
ities was not conducted in full compliance with NRC requirements, as set
forth in the Notice of Violation, enclosed herewith as Appendix A.
This
1
item of noncompliance has been categorized into a level as described in our
correspondence to all NRC licensees dated December 31, 1974.
This notice is sent to you pursuant to the provisions of Section 2.201,
of the NRC's " Rules of Practice," Part 2, Title 10, Code of Federal Regu-
lations. Section 2.201 requires you to submit to this office, within twenty
(20) days of your receipt of this notice, a written statement or explana-
tion in reply including (1) corrective steps which have been taken by you
and the results achieved; (2) corrective steps which will be taken to avoid
further violations; and (3) the date when full compliance will be achieved.

The corrective actions described in your several letters that reported
and discussed the five occasions in October, November and December 1979
when chlorine concentrations in the plant effluent exceeded the Technical
Specification limit of 0.2 mg/ liter were examined during this inspection.
According to the information we obtained during the inspection, the use
of chlorine in the circulating water and sewage treatment systems was such
that plant effluent concentrations of chlorine would be a significant per-
centage of the limit during normal operations.
Your letters described spe-
cific corrective actions for each of the instances of excessive chlorine
concentration.
However, we believe that an integrated action plan is nec-
essary for your chlorination program to preclude the multiple occurrences
of releases above..the_.1.imit
Therefore, your response to Appendix A should
not merely iterate actions as described in your previous occurrence reports,
but should present a consolidated program intended to preclude reoccurrence.
In accordance with Section 2.790 of the NRC's " Rules of Practice," Part 2,
Titla 10, Code of Federal Regulations, a copy of this letter and the en-
closed inspection report will be placed in the NRC's Public Document Room.
If this report contains any information that you believe to be proprietary,
it is necessary that you submit a written application to this office, with-
in 20 days of the date of this letter, requesting that such information
be withheld from public disclosure. The application must include a full
statement of the reasons why it is claimed that the information is propri-
etary. The application should be prepared so that any proprietary infor-
mation identified is contained in an enclosure to the application, since
the application without the enclosure will also be placed in the Public
Document Room.
If we do not hear from you in this regard within the spec-
ified period, the report will be placed in the Public Document Room.
Should you have any questions concerning this inspection, we will be glad
to discuss them with you.
Sincerely,
,
f f/Sud
