INSPECTOR'S EVALUATION RO INSPECTION REPORT No. 50-289/74-34
THREE MILE ISLAND UNIT 1
The special inspection performed to evaluate the status of the previously
identified enforcement items revealed much improvement in the overall
program.
The program administration was shifted to the Reading office
and that group appears to have a good handle on the program. The Plant
Operations people also are involved with respect to routine maintenance
and a surveillance program which serves to identify any missing sample
or analysis.
One of the violations identifed during this inspection was in regard to the
sensitivity of I-131 analysis in milk.
I have identified this area as a
generic problem in a previous memo to you dated November 8, 1974, in which
I said that only one laboratory (RMC,) in our region appeared to be capable
of meeting the "0.5 pCi of I-131/ liter of milk within an overall error of
25%" sensitivity of analysis requirement imposed by the newer Environmental
Technical Specification.
TMI uses RMC to analyze their milk. The data showed
that while RMC could meet this requirement most of the time, it could not do
it all of the time. This re-enforces the statements in the above referenced
memo that licensees with the above milk sensitivity requirement will have
much difficulty in meeting it.
In IMI's case, by prompt notification from
RMC and resampling milk when analytical difficulties arise, TMI can probably
live with this limit. However, if the required sampling intervals were
shorter, such as Peach Bottom has (1 week), this resampling would not help
as there would be insufficient time between samples to replace 4" bad sample."
With respect to the Appendix B, Technical Specifications, the radiological
environmental monitoring program should be upgraded in several areas to be
consistant with the AEC Standard Environmental Tech Spec. Guide. These
areas are identified below.
1.) Air particulate filters should be composited for quarterly Sr-89
' and 90 analyses.
The method of compositing, i.e. filters from each
station or from all indicator stations, should be indicated for the
strontium, as well as, for the gamma spectral analyses.
'
2.) Milk should be analyzed for Sr-89 and 90 and by gamma spectral
analysis monthly.
