Services
Our position in the market is reinforced by our extensive offering of services. These services are in place to allow our staff of nuclear professionals to be available 24/7 – and our on-site NRC licensed RCA facility and radioactive material shipping license allow us to rapidly mobilize for emergent situations.
Outage Services
R.O.V.’s mission is to support the industry’s goal of reduced radiological dose received by nuclear workers. In addition to our current range of systems and services, we are investing in research and development of new and progressive time and dose saving solutions for our customers.
Below is a chart that contains the routine and non-routine outage tasks as well as non-outage tasks that R.O.V. performs on a regular basis. Most of the tasks performed have been documented to contribute directly to critical path savings, ALARA savings, or both.
Tasks that contribute directly to critical path and/or ALARA savings are identified by either a CP or an A on the chart below.
