What does "scientific report" mean?
I would construe "scientific report" here to encompass all forms of scientific publication and communication, including peer-reviewed papers as well as possibly internal technical reports. Remember that a technical report is just something that hasn't gone through peer review. 

The exception would be if this were for a corporate position, where publication may be more difficult. In such cases, one would expect "grey literature" to be the primary "publication" mode.
