In many respe::a the plant is cimi-1er to the plcats prcpo:cd for Quad-Citics. Erver, this pl:nt is tha.first United States nucicar plant to uso a ficid-crected proauura vescel. Although field cractica of 12rac preacura ve:ccia is n:u to the ras:ter infu;try, it is not a new precedure. With the fabrication techniques propoacd and with
=cticulous caro end dilicence in the quality control procran, it is the cpinica of the Acas th:t a hi:h-quality ficid-crected pras uro ve;;21 for the Monticello plant can be constructed. The Ccmittee rece=cada that the strc:s analysis report for the reactor vessel ba reviewed by independ-ent c::perta.

It is cur understanding that valves of c:: _n.:Sil; iC..tical d:31:n vill be tested under sinulated cecident ccnditione.
It is recc=2ndad th:t the Ec;ulatory Staff satisfy it:cif with reap:ct to tha edcquacy of tha icolation valva tcat pro,rca and follou the develop: ant of the datailed design of tho.:bove systc=s.
' \\
It is of Orcat importance that sufficient cicetrical power is cvailabic at the plant to cperato c::racacy core coolin; equipment in the unlikely cvant of loss of r.ornal coolant to the cc:c. Althcuah the reliability.of off-site pc ect usa stated to be very hi3h, it is the rccccc.andation of the ACRS tha the Monticello plant includo a sceond dicscl generator of the samo ccpacity-as the one propo:cd.
The Advisory-Comittec cn neceter Safecuards believes that the ite 3 man-tier.cu r.~.xua ca.: a ra.,olved durin; constructica and that the propc;cd re-accer c:n be c;natructed at the Monticello site with reaacnabic assurcnco that it can ba operated at powcr Icycla up to 14691G(t) without undue risk to the health and safety of the public.
