Terms of services - Nominatim

I am currently studying data analysis. To finalize the studies I have to finish own project (together with my colleague) For this purpose we need to get street names of about 100 000 places. For this I would like to use the Nominatim services. As far as we understand the terms of use of Nominatim services this amount of requests can be considered violation of the terms of use. Is it possible to use Nominatim services in this case? This amount of requests is only one time and the data received by the service will not be used for commercial purposes.
