Research And Development Department

About Department

The vital role of research is to advance and refine knowledge and provide solutions to problems facing society at local and international levels. It is in this contention that TAEC established the department of Research and Development to enhance implementation of the research culture in nuclear and radiation technology in the country. The overall objective is to create an innovative contribution of nuclear technology applications by doing researches in various under-researched areas to stimulate the Tanzanian economy and the world. The department is responsible for organizing, soliciting and administering research funds from donor, internal and external grants and handling of researches, projects, innovation and handling training programs in nuclear and radiation technology. It is for this reason TAEC maintains several nuclear analytical laboratories that support research activities and provide training to various stakeholders. Various research proposals and projects are encouraged to augment national priorities in agriculture, livestock development, natural resources, human health, nutrition and environment, taking into consideration available human and other resources important areas.

TAEC has set aside research funds for the financial year 2022/2023. Researchers from within TAEC are highly encouraged to submit proposals for review and funding consideration. Individuals and research groups are highly encouraged to take immediate actions. The Research and Development Section has proposed a timeframe which researchers must follow for smooth implementation of research activities. The submission and evaluation of proposals is therefore scheduled in three phases as detailed below:

Phase I

Research proposals for Phase I will be processed in the fourth quarter (April to June) of each financial year. This means that submission of proposals, review and evaluation by the Technical Committee (TC) will be conducted in the 4th quarter and funds will be requested in the first week of July.

Phase II

Research proposals for Phase II will be processed in the first quarter (July to September) of each financial year. This means that submission of proposals, review and evaluation by TC will be conducted in the 1st quarter and funds will be requested in the first week of October.

Phase III

Research proposals for Phase III will be processed in the second quarter (October to December) of each financial year. This means that submission of proposals, review and evaluation by TC will be conducted in the 2nd quarter and funds will be requested in the first week of January.

In summary, the implementation will be guided by the schedule below:

Phase Month Activity
I April Submission of proposals for phase I
May First review of proposals and feedback to authors
June Resubmission, second review of proposals and TC evaluation
II July Funding for phase I and submission of proposals for phase II
August First Review of proposals for phase II and feedback to authors
September Resubmission, second review of proposals and TC evaluation
III October Funding for phase II and submission of proposals for phase
November First review of proposals and feedback to authors
December Resubmission, second review of proposals and TC evaluation
