This letter transmits additional infortration or clarification in regard to our responses dated February 9, 1983 and November 23, 1983 concerning emergency power and post accident chloride analysis.
Sincerely, 1

ENCLOSURE-I
[
Criterion: (1)
The licensee shall have the capability to promptly obtain reactor coolant samples.and containment atmosphere samples.
The combined time allotted for sampling and analysis should be three hours or less from the time a
' decision is made'to take a sample.
Response
Our response'to this criterion provided in our letter of Februray 9, 1983 stated-that the new gamma spectrometer with multichannel analyzer and vacuum pump was being placed on the emergency power system.
This modifi-cation is expected to be complete by February,1984. However, in the interim,
- this equipment can be placed on emergency power using temporary cables within -
the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> specify limit in the event of loss of offsite power.
Instructions are being prepared to make the required cannections if it became necessary to do so prior to ' completion of the design modification. These instructions will be incorporated into an Emergency Procedure by January 15, 1984*
~
LCriterion: (5)
The Licensee shall provide for a chloride analysis to be completed within 4 days.
Response
Our response to this criterion provided in our letter of November 22, 1983 stated that chloride analysis would be performed using the ion chromotograph and a procedure would be available in January 1984.
In order to reduce exposure to personnel, the procedure will require an auto sampler and con-troller which is currently located.in Reading, PA (about 65 miles from TMI) at our system laboratory.
In the event of an accident requiring a chloride
. analysis, the autosampler would be transported to the site and be available for performing the chloride' analysis well within the four days as required.
- Similar equipment is being purchased specifically for TMI-l and CPU expects to have it available at the site by April, 1984.*
- Until'such time that the hardware modification or equipment items are in place'as described, these procedures will remain in effect to assure cC+;eate post acci' dent sampling analysis capability.
