1979 MEMORANDUM FOR:
L. G. Hulean, Chief, Hydrology-Meteorology Branch, DSE FRON:
R. P. Denise, Assistant Director for Site rechnology, DSE
SUBJECT:
LESSONS LEARNED FROM THREE MILE ISLAND While things are still fresh, and befom the staff becomes burdened with additional requests for information, I believe that we should record the lessons learned on Three'Hile Island.
I believe that the Hydrology-Matercrology Branch can make a particularly effective con-tribution to this because of early and continuing involvement, particularly meteorology. You are requested to make such an assign-inent to your staff, establish broad gridance, and establish the schedule. The fom of the report neet" not be established yet, i.e.,
to whom and distributton.
Some things I would like to see addressed are:
(a) Availability of meteorological data for use in dispersion and dose calculations. This should be addressed on a time basis, i.e., recognizing more contributors as time elaDsed.
(b) Applicability of data to site specific conditions, including the river valley impacts.
(c) Procedures and problems in establishing contact with local and National Weather Service people #
use of on-site data.
(d) Available raodels for their use for dose calculations, including CRAC, Livermore, etc.
(e) Hydrology assessments made for river spills, avail-ability of data.
7904270OM (f) Availability of plant and regional base infomation to staff.

s-L. G. Hulman The thrust of the effort should be to accurately portray what was encountered, what was observed, what was tried, what failed to werk (attempts, not plant equipment), what worked, how problems were overcome, ava11' ability of infomation not recognized, personnel difficulties, working conditions and their unpact, organization of work, etc. We should then follow with an assessment of where things would be expected to be different at other sites (for example TNI had gcod sources of meteorology data, others would not), what could be done in such cases, how things might need to change at the plants, etc.
Finally, we should draw out the lessons learned and reconmenda-tions for change.
I recognize the resources crunch, but feel that this is important.
I would be pleased to discuss the matter fully with you and your involved staff.
