SUBJECT:
REPORT ON MANUFACTURING LICENSE FOR THE FLOATING NUCLEAR PLANT
Dear Dr. Palladino:
During its 258th meeting, October 15-17, 1981, the Advisory Committee on Reactor Safeguards completed its review of the application of Offshore Power Systems (OPS) for a license to manufacture eight standardized Floating Nu-clear Plant (FNP) units at a facility located on Blount Island in Jackson-ville, Florida. The Committee had most recend y commented on this applica-tion in a letter to the Executive Director for Operations, dated April 16, 1980 addressing the installation of a core ladle in the FNP.
The Committee had earlier commented on other aspects of this application in Interim Re-ports (December 10, 1975, and June 7,1976) and in letters pertaining to
^
the Platform Mounted Nuclear Plant (November 15, 1972), the Atlantic Generat-ing Station (October 18,1973), and the Liquid Pathway Generic Study (Novem-ber 18, 1976 and May 9, 1978).
The Committee also had the benefit of the documents listed.
At a Subcommittee meeting neld on October 13, 1981, the NRC Staff indicated that there were no outstanding issues that needed to be resolved prior to issuance of a manufacturing license.
Hoyever, the NRC Staff has identified many issues, most of which are generic, that will require further evaluation before issuance of a Final Design Apprcval.
In the main, these issues per-tain to accident situations and include protection of the reactor pressure vessel during transients, hydrogen control and subcompartment differential pressure analysis within cordainment, automatic initiation of and indication of flow in the auxiliary feedwater system, and the upgrading of emergency support facilities.
All such items should be resolved to the satisfaction of the NRC Staff.
The Committee wishes to be kept informed.
OPS has committed to do a detailed Probabilistic Risk Assessment (PRA) on the plant.
This assessr.ent is to be similar to tne NRC Interim Reliability Evaluation Program (IREP) and will be designed to determine and quantify accident sequences that are dominant contributors to the potential for core i
damage.
OPS plans to conduct uncertainty and aensitivity studies as part of this assessment and to use the results to identify changes to be implemented in the final FNP design. We endorse this approach.
However, we believe it b
O ki m o &.

^
l-Honorable Nunzio J. Palladino Octnber 19, 1981 is important that OPS recognize the limitations of current PRA techniques and that, where necessary, t?ey be prepared to address certain of the unresolved issues using other methods. --
~"
We are encouratjed to-nots changes nrade in-thy proposed design of the con-tainment vessel, particularly with respect to the substantial increase in the design pressure. This represents, in our opinion, a significant increase in the ability of the FNP to withstand a major accident involving large re-leases and subsequent combustion of hydrogen. We note also that, while OPS has elected to use a distributed ignition system in the FNP, they will per-form a etudy to evaluate other possible means of hydrogen control.
We note the following NRC Staff comments concerning limitations on the siting of the FNP units.
In Part III of the Final Environmental Statement, the ' Staff concluded that "... there is a reasonable degree of assurance that tne eight plants proposed for manufacture can, with suitable mt,difications.
be sited and operated as electric generating stations at yet to be specified sites in the offshore and shore zone waters of the Atlantic Ocean and the Gulf of Mexico." The NRC Staff stated also that applicants wishing to site and operate such plants in uther locations such as rivers, estuaries, or near barrier islands would "... have to demonstrate appropriate mitigation actions that would provide both an acceptable level of environmental impact as well as an acceptable level of core-melt accident risk." We expect to consider these issues when specific applications are reviewed.
Subject to the above comments, and to recommendations in previous Committee reports, the Advisory Committee on Peactor Safeguards believes that the Floating Nuclear Plant units can be manufactured with reasonable assurance that they can be sited and operated without undue risk to the health and safety of the public.
Sincerely, J. Carson Mark Chainnan
