Question: Where did the submarine whose reactor was designed by Zalman Shapiro complete a first submerged transit?

Context paragraphs:
Operation Sandblast: Operation Sandblast was the code name for the first submerged circumnavigation of the world, executed by the United States Navy nuclear-powered radar picket submarine  in 1960 under the command of Captain Edward L. Beach.  The "New York Times" described "Triton"' s submerged circumnavigation of the Earth as "a triumph of human prowess and engineering skill, a feat which the United States Navy can rank as one of its bright victories in man's ultimate conquest of the seas."

Zalman Shapiro: Zalman Mordecai Shapiro (12 May 1920 – 16 July 2016) was an American chemist and inventor.  He received 15 patents, including a 2009 patent on a process to make commercial production of diamonds cheaper, and played a key role in the development of the reactor that powered the world's first nuclear powered submarine, the "Nautilus".

ZED-2: ZED-2 (Zero Energy Deuterium) is a zero-power nuclear research reactor built at the Chalk River Laboratories near Chalk River, Ontario, Canada.  It is the successor to the ZEEP reactor.  Designed by AECL for CANDU reactor support, the unit saw first criticality on 7 September 1960.  The reactor is still operating at Chalk River where it is used for reactor physics and nuclear fuel research.

Soviet submarine K-11: K-11 was a Soviet November-class (Project 627A) nuclear-powered attack submarine that had two reactor accidents during loading of the nuclear reactor core in Severodvinsk on 7 and 12 February 1965.  Reasons for the accidents included nonobservance of operating instructions by those participating in the lift of the reactor cover and the mistaken decision to continue refueling after the first accident.  There were no fatalities but those accidents (ejection of radioactive steam and inappropriate fire extinguishing methods on 12 February) caused an unsafe release of radiation into the environment and nearby shipyard area.  Seven men were treated for exposure to radiation.  The reactor compartment holding the two damaged reactors was removed, partially decontaminated and sunk in Abrosimov Bay (east coast of Novaya Zemlya) in the Kara Sea in 1966.  A new reactor compartment was installed and the submarine continued to perform her duties from August 1968 (performed 5 long-range cruises in 1968–1970 including patrol missions in the Mediterranean Sea, 4 long-range cruises in 1975–1977, 5 long-range cruises in 1982–1985) until decommissioning on 19 April 1990.  K-11 passed the milestone of 220,179 miles traveled in 1988.  The submarine has been laid up in Gremikha Bay since of 2000.

Peral Submarine: Peral was the first electric battery-powered submarine, built by the Spanish engineer and sailor Isaac Peral for the Spanish Navy.  The first fully capable military submarine, she was launched 8 September 1888.  She had one torpedo tube (and two torpedoes) and an air regeneration system.  Her hull shape, propeller, and cruciform external controls anticipated later designs.  Her underwater speed was 3 kn .  With fully charged batteries, she was the fastest submarine yet built, with underwater performance levels (except for range) that matched those of First World War U-boats for a very short period, before her batteries began to drain.  For example, the SM U-9, a pre-war German U-boat built in 1908, had an underwater speed of 8.1kn, and an underwater range of 150 km at 5.8kn, before having to resurface to recharge her batteries.  In June 1890, Peral's submarine launched a torpedo while submerged.  It was also the first submarine to incorporate a fully reliable underwater navigation system.  However, conservatives in the Spanish naval hierarchy terminated the project despite two years of successful tests.  Her operational abilities have led some to call her the first U-boat.

USS Nautilus (SSN-571): USS "Nautilus" (SSN-571) was the world's first operational nuclear-powered submarine.  The vessel was the first submarine to complete a submerged transit of the North Pole on 3rd August 1958.

Sangameswara Temple, Kurnool: The Sangameswara temple is an ancient Hindu temple in the Kurnool district, Andhra Pradesh, India.  It is located near Muchumarri at the confluence of the Krishna and Bhavanasi rivers, in the foreshore of the Srisailam reservoir, where it is submerged for part of the time, surfacing when the water level recedes to a sufficient degree.  It was first submerged after the Srisailam Dam was constructed in 1981, and first surfaced in 2003.

Clementine (nuclear reactor): Clementine was the code name for the world's first fast-neutron reactor.  It was an experimental-scale reactor.  The maximum output was 25 kW and was fueled by plutonium and cooled by liquid mercury.  Clementine was located at Los Alamos National Laboratory in Los Alamos, New Mexico.  Clementine was designed and built in 1945–1946 and first achieved criticality in 1946 and full power in 1949.  The reactor was named after the song "Oh My Darling, Clementine."  The similarities to the song were that the reactor was located in a deep canyon and the reactor operators were 49'ers, as 49 (last digits of element 94, isotope 239) was one of the code names for plutonium at the time.

1966 Soviet submarine global circumnavigation: The 1966 Soviet submarine global circumnavigation was announced to be the first submerged around-the-world voyage by a group of Soviet nuclear-powered submarines.

MOATA: Moata was a 100 kW thermal Argonaut class reactor built at the Australian Atomic Energy Commission (later ANSTO) Research Establishment at Lucas Heights , Sydney.  Moata went critical at 5:50am on 10 April 1961 and ended operations on 31 May 1995.  The reactor was shut down as it was no longer possible, after 34 years, to economically justify its continued operations.  It was one of a group of reactors that were designed in the mid-1950s, in the United States by the Argonne National Laboratory.  The purpose of the reactor was for training scientists, however in the mid-1970s it was expanded to include activation analysis and neutron radiography.  Moata offered training in reactor control and neutron physics.  Experimental data on nuclear fuel and moderator systems was also accumulated during the operation of the reactor.  The reactor has since been permanently shutdown and with dismantling of the reactor complete the site has been completely restored.  It was the first reactor to be decommissioned in Australia.  In 1995 the used fuel from the reactor was unloaded and in 2006 it was shipped to the United States where it remains.  "Moata" was dismantled in 2009.  "Moata" is an Aboriginal name meaning "gentle-fire" or "fire-stick".
