Dear Sir:
Three Mile Island Nuclear Station, Unit 2 (TMI-2)
Operating License No. DPR-73 Docket No. 50-320 Reactor Building Fire Hose Stations There are six (6) Fire Hose Stations servicing the containment, two cach on elevations 367', 305' and 282'.
The Fire Hose Stations consist of hose reels with 100 ft. of 1 " Q rubber hose (with a nozzle) and an isolation valve at the reel.
It is assumed that at this time the rubber hoses have exceeded their serviceable life and are therefore considered inoperable.
The Recovery Technical Specifications, Section 3.7.10.4 require the Fire Hose Stations listed in Table 3.7-4 (which include the six listed above) to be operable at all times. However, the Action Statement allows ALARA considerations in determining corrective actions if one or more should become inoperable. Further, a footnote to the " Reactor Building" section of Table 3.7-4 acknowledges the Action Statement allowance for ALARA and the possible inoperability of the in-containment Fire Hose Stations. The foot-note requires that the " Fire Hose Stations in the Reactor Building shall be OPERABLE prior to initiating operations which generate combustible materials, and prior to initiating operations which involve the use of open flames, welding, burning, grinding, etc.".
At this time elevation 282' is inaccessible and there are no plans to perform any activities on that elevation, including those which would generate combustible material or involve open flames, welding, burning, grinding, etc.
However, neither will we be able to install new hoses on elevation 282' 00$
because of accessibility considerations.

We have previously committed to install new hoses on the hose stations on

Experiment. Although we are planning no activities that involve open flames, o
welding, burning, grinding, etc., as a part of the Decon Experiment, the b
experiment will generate small amounts of combustible materials, mostly in the form of disposable plastic from anti-contamination clothing. For this Q
reason, Technical Specification Table 3.7-4 would require the six hose reel n
stations to be operable prior to the start of the Decon Experiment.
Since the o n:E GPU Nuclear is a part of the General Public Utikties System
4
. 4400-82-L-0016 Mr. L. H. Barrett reels on eleyation 282' will. remain inoperable, we would normally go to the Action State 6ent, which requires running another hose in the area if dose considerations (ALARA) permit. This letter is to advise you that, at the present time, we do not believe the accessibility of elevation 282' would permit installation of a new hose at the fire hose station, nor would it permit installation of an alternate hose.
In summary, we intend to proceed as follows:
1.
Install new hoses at the stations on 305' and 367' elevations prior to commencement of the Decon Experiment.
2.
Do not install new hoses at elevation 282', and do not run an alternate 4
hose at that level. When elevation 282' becomes accessible and prior to generation of combustible materials or performance of activities which involve open flames, welding, burning, grinding, etc., on that elevation, we will install new hoses on the hose reels in 282' elevation.
Please call if you have any questions.
