(AITS NO. F30178110)
Attached is a copy of a letter dated April 27, 1976, from L. O. Mayer,
Manager of Nuclear Support Services, Northern States Power Company,
pertaining to the IE Inspection Report No. 050-263/76-05. Two points
on the meteorological program and elevated radioiodine levels raised
in the NSP letter in response to our inspection report were brought
to your attention in a acparate memo dated April 28, 1976, for
action (AITS F30178HO, revised completion date 6-10-76). Our memo
was sent to you prior to our receipt of the NSP letter. We would
appreciate receiving a prompt response to this AITS item so we can
prepare a followup response with the IE position to the items
addressed in the NSP letter. In accordance with the above, please
provide an interpretation of Technical Specification 6.7.A.2.h(2) when ,
the concentration levels in various environmental media indicate the
likelihood of public intakes in excess of 1% of those that could
result from continuous exposure to the concentration values listed
in Appendix B, Ta~leo II, Part 20.
We alsn understand that interim Technical Specifications on Section-
2.4 Radioactive Ef fluents and Section 4.8 Radiologici i Environmental
Monitoring Program are being prepared. Our commente on the proposed
T/S change request of October 15, 1975, and March 1, 1976, were
also sent to you on April 28, 1976. We believe it is necessary to
include a T/S change in the plant reporting requirements to clarify
the intent of Technical Specification 6.7.A.2.h(2).
Plcase provide guidance on how we can obtain information such as
meteorological data from the licensee in accordance with Regulatory
Guides 121 and 4.8 when such data are not renuired in the Technical
Specifications.

Your letter dated April 8,19/6, which was roccived on April 9,1976, transmitted
IE Inspection Report No. 050-263/76-05. 'The Inspection Report states at two
points that certain items of discussion will be referred to the Office of Nuclear
Reactor Regulation and will be ny amined at subsequent inspections. *1his letter is

NSP took the position that there are no regulatory requirements or Technical
Specifications covering the Monticello plant which require the submission of
meteorological data. We further pointed out that the NRC Regulatory Guides are
not requirements. The discuccion that ensued from that point on uas with respect
to the recommandations contained in Regulatory Guides 4.8 and ' .21 for inclusion
with the semiannual effluents report of meteorological data and dose computations.
We have reviewed the impact of a reporting requirement of this nature and find
that a considerabic initial investment in manpcuer, ccxuputer programs, consultant
help and equipment would be required to provide this type of data. In addition, it
would require a continuing manpcuer requirement, beyond that which we currently
have avai1M 'e, and possibly intermittent or continuous consultant help to provide
the data that the NRC proposes to be submitted each six months.
We carried the discussion further with the observation that the NRC is supplied
wi th site meteorology which is used in a conservative manner with plant effluent
infonnation t o set regulatory limits on radioactive effluents from the plant and
highly conservative design objectives. 'lhis is coupled with requirements for an
ext.cnuive Radiation Environmental Monitoring program to confirm that the limits
l and design objectives have been set at such a 1cyc1 that there are no unexpected
l cffects on the er.vironment from radioactive offinent releases from the plant. We
L
made the concluding observation that the nemlannual subminsion of meteorological
! data and dose calculations would appear to be more of a data collection ef fort

than information that is needed for the assessment of safety related activitics
and that the manpuser and equipment expenditures that would be involved appear to
be unwarranted.
Several years ago NSP began work on a research project for providing transmission
of meteorological and of fluent data from NSP's fossil and nucicar plants to a
centralized computcr-oriented data collection system. A prototype " digitizing
transmitter" vas built, t ested, and installed at the !!onticello plant on the
meteorolegical tuser about nine months ago. The " digitizing transmitter" operation
has been reasonably successful for the purpose intended, but it has not been It was
suit abic for use for submittals to the NRC, such as Appendix I compliance.
also intended that a teletypewriter would be provided in the Monticello control
room to provide supplemental recording of the " digitizing transmitter" information.
It should be noted that the Monticello control room aircady has a wind direction
and velocity recorder in operation. Since the teletypcuriter system is based
,
on use of the prototype device, which might be replaced with more suitabic equip-
ment, it has been decided not to install this supplemental equipment in the
Monticello control room. Meteorological data continues to be obtained from the
,
300' tower in strip chart form and is retained in accordance with recordkceping
requirements.
Paragraph h on page 12 reference a computer printout as being availabic, but not
in use. This is information frcu the prototype " digitizing transmitter" equipment
and is not in a format or of the ;uality which could be put to beneficial use by
the nuclear plant. It should also be noted that the licensec is currently hand
reducing data from the metaorological strip charts in order to obtain a full year
,
j
of acceptabic quality meteorological data in connection with the Appendix I
compliance submittal. This infomation will update the meteorological data that
'
has been provided to the NRC in earlier submittals.

Since the Monticello plant does not have Appendix B Technical Specifications, the
conuncut in regard to ECAD maintaining cognizance of aquatic biota protection con-
ditions, reporting to NSS when protection conditions are exceeded, etc. , is not

applicabic to the Monticello plant at the present time.
+ The NSS Department .does not have administrative responsibility for non-radiological
sampling as mentioned in the second sub-paragraph. The !!SS responsibiliLy for a

reductiod and computer processing of the meteorological program results is not
routine responsibility but resulted f rom the needs for obtaining this information
on a one-time basis for the Appendix I cuepliance submi.ttal. The tiSS Department

A revised Radiation Environmental Moultoring Program was submitted to the Ccmmission
on October 15, 1975 as a license amendment request; the program has not yet been
put into effect since the licenso amendment has not been issued by the NRC. The
March 1, 1976 submittal referenced in the inspection report involves interim
Technical Specifications on radioactive effluents; the Radiation Environmental
Monitoring Technical Specification pages that were included uith the liarch 1,1976
submittal were included only because there are changes in pagination in this section
due to the removal of radioactive effluents from Appendix A and their transfer to
Appendix E. .

The inspection report correctly reficcts the increases in icvels of I-131 in milk
during the summer of 1975; hauever, it does not point out that these Icvnis have
been greatly reduced since replacement of the defective initial 7x7 fuel during
the refueling outage in October, 1975.
On the bottom of page 10 and the top of page 11, still under parsgraph d, there is
a discussion of the number of iodine sampics which should be included in the
averaging to determine if additional repprting is required on estimates of likely
exposurcs to individuals and population groups. The Technical Specification re-
quirement for supplemental reporting is based en the likelihood of intakes in .
execca of 17. of thosc that could result from continuous exposures to the concen-
tration values of Appendix B, Tabic II, Part 20. This appears to be similar to
design objective reporting. It is our position that the sampics should be
averaged over a calendar quarter and if the average concentrations of I-131 in
milk are greater than 2.4pci/1, then the supplemental information would be required.
