Dear Mr. O'Reilly:
Subject:
Oyster Creek Station Docket No. S0-219 Missing Environmental Air Particulate Samples The following information report is being submitted in accordance with a discussion between Mr. E. Greenman of your staff and Mr. J. T. Carroll, Jr.,
Superintendent of the Oyster Creek Nuclear Generating Station.
On August 12 and 13, 1974, a routine environmental collection of air particulate and charcoal filters was performed. The filters that were collected had been put in service on July 29, 30, and 31, 1974. The stations involved were five locations required by the Oyster Creek Technical Specifications and three additional locations used as background stations.
The filters were removed per the instructions on the appropriate check-off sheet and each sheet properly filled out and signed by the technician.
The removed filters were then brought to the plant where they were labeled and shipped by mail to Teledyne Isotopes (the vendor) on August 14, 1974.
During the time the filters were waiting shipment at the plant, they were kept in an office that is normally locked at night.
On August 15, 1974, the vendor contacted plant personnel and' informed us that the samples had arrived but that there were no particulate filters with them. The charcoal cartridges and the glassine envelopes, normally used to keep the particulate filters in, were both in the sample packets but there were no particulate filters in the glassine envelopes. An in-house search was conducted, but the filters were not located.
The vendor was contacted several times and asked to recheck the in-coming samples at their facility.
However, the filters were still not located.

s' Mr. O'Reilly August 26,- 1974 The technician that changed the samples was questioned and said that. he
)
didi in fact, change the filters,-put them in the glassine envelopes, and sealed them in the sample packet along with the charcoal filters. He also indicated that once-the envelopes were sealed, he never opened them again prior to shipment.
Several of-the stations 1were revisited in case, by mistake, the filter could have been left inside the station, but none were found. At one station,
~
thefparticp1 te filter that was presently in, service was removed and compared
/
with the. :4me type of filter removed from an emergency air monitor located approximately ten feet from the environmental monitor. ~ That filter had been installed _ one week prior to the environmental filter change and, in fact, contained more deposit than the comparable filter from the environmental station. This also seems to verify that the filters were actually. changed.
~
The safety' significance of this event is minimal. Although the particu-
. late gross. 8 values in the environment are not known for the two week period in question, the particulate emissions from the stack during this time were at,
i or below those measured during previous periods of plant operation. Environmental concentrations of particulate activity that are plant related, dierefore, would not have been in excess of that measured during comparable periods in the past.
Very truly yours, C

Dear Mr. O'Reilly:
Subject:
Oyster Creek Station l
Docket No. 50-219 RO Inspection Report No. 50-219/74-13 l
\\
This letter is in reply to your letter of July.24,1974 to Mr. Ivan R. Finfrock, Jr. regarding the inspection of Oyster' Creek operations that was conducted by Mr. Rebelowski of your office on ? uly' 10-12, 1974.
J Prior to placement of RO Inspection Report No. 50-219/74-13 in the Public Document Room, one discrepancy should be resolved.
It is as follows:
Description of Violations, Item 2 l
The second paragraph states, in part, the core spray system was inoperative for about 15 minutes with irradiated fuel in the reactor vessel (Severity Category 2).
This statement i
implies the complete loss of all core spray capability when in reality the station had lost redundancy in the system and did have available a completely operable core spray loop, as re-ported in our Abnormal Occurrence Report No. 50-219/74-28.
This point is properly stated in the detailed report, section 4 on page 5.
Vc,ry truly yours, b
