Gentlemen:
This refers to the inspection conducted by Mr. Fishbaugher on November 28
through December 1, 1972, of operations at the Dresden Unit 1 plant
authorized by AEC Operating License No. DPR-2, and to the discussion of
our findings held by the inspector with Messrs. Worden, Diederich, and
Roberts of your staff at the conclusion of the inspection.
Areas examined during this inspection included recent operating experience,
organization / administration, facility procedures, reactivity, and power
control, reactor coolant and auxiliary systems. Within these areas, the
-
i
inspection consisted of selective examinations of procedures and repre-
sentative records, interviews with plant personnel, and observations by
the inspector.
In addition to the above matters, the inspector examined your completion
of preoperational testing, emergency procedure, surveillance procedure,
and operator orientation for the newly installed core spray system
identified in our letter of November 13, 1972. We have no further ques-
tions on these items at this time.
During this inspection, it was found that certain of your activities appear
to be in noncompliance with AEC requirements. The items and references to
the pertinent requirements are listed in the enclosure to this letter.
This letter is a notice of violation sent to you pursuant to the provisions
of Section 2.201 of the AEC's " Rules of Practice," Part 2, Title 10, Code
of Federal Regulations. Section 2.201 requires you to submit to this office

Paragraph B.15.b(1) of the Technical Specifications sets 1000F as
A.
a maximum temperature limit for the emergency condenser shell-side
water.
Contrary to the above requirement, shell-side water temperature
