Same literature survey in first and final reports, Is it ok?
In some institutions, one of the goals of the provisional report is to get the student to write something that will eventually be included in their dissertation/thesis. In this way the student feels that he or she has already made a start on the (dreaded) writing up process and therefore feels confident that - in further small, incremental steps - the rest of the document can be created. 

In such cases, it would be unreasonable to consider the re-use of the literature review appearing in the provisional report in the final work as being plagiarism. 

Matters may be a little different if the initial report was published in some manner, and released outside of the institution. As per one of the comments to your question so far, get your advisor's input.
